Step-by-step instructions on how to properly change the car yourself. how to change tires on alloy wheels how to change tires on a car

And vice versa. Services of a mechanic at a tire station and an hour and a half time. Just something and worries. Given that almost all motorists, when buying seasonal tires for a car, purchase a second set rims. After assembly and installation, further tire changes come down to replacing the wheels with mounted tires corresponding to the season. Removed wheels after washing and drying, they are sent for storage in a secluded place, usually in the basement. Conditions in a normal ventilated basement are most suitable for storing replacement rubber.

Some drivers, due to their ability to plan and organize work for the week ahead, bring replacement wheels to the tire shop in advance. The wheels are inspected and balanced, pumped up to the required pressure and installed upon the arrival of their owner.

The question of time has always been painful. On a day off, I don’t really want to waste precious time on a routine, there are a lot of different things to do and problems. Moreover, it will not work to combine changing tires and going shopping with the family - the trunk will be clogged with wheels with replaceable tires. The spare wheel and tools will have to be transferred to the interior of the car. In addition, when you need to “change shoes” for a car due to snow, ice or a sharp drop in temperature, there will be a decent queue of people at the tire change station.

Usually, when the situation on the road is already critical and it is simply unsafe to postpone the replacement of tires, you have to go to the tire changer after work, at night. After a couple of hours of waiting in line, a worker at the station will show you the place where your "seagull" will change shoes, accept a set of tires from you and offer to wait half an hour or an hour.

As a rule, the main area in the box, where car maintenance takes place, is packed with “serious” cars. For ordinary customers, an adjacent asphalt parking area is offered. Usually such places are poorly lit, at best there are a couple of lights to illuminate the surveillance cameras. For the master, the lack of normal lighting is not a hindrance at all.

In the heat of "conveyor fever" most of the operations of unscrewing the wheel nuts and subsequent replacement with a new one, they can do with eyes closed to the touch. Which, by the way, very often happens at the end of the shift, what can you do - people are not robots and hard physical labor exhausts even young and seasoned guys. Their earnings directly depend on the number of clients served. The period when drivers change seasonal tires is just as important for them as for specialists in straightening car linings, the first real ice of the season, popularly called “tinker's day”.

During this period, everyone is in a hurry at the tire changer station. Hurry customers who have a lot to do and do not want to wait in line. Workers and craftsmen are in a hurry, fearing to lose customers and earnings, so everyone is trying to work with minimal loss of time and effort.

There are many unfavorable factors, the quality of work is falling. Therefore, do not be too lazy to use a flashlight stored in advance and carefully examine the results of the work:

First. We will make sure that your tires are installed on your car. There are no damages on the rubber, fresh cuts, the level of air pressure corresponds to the required norm. Pay attention to the fresh balance weights on the discs. They must be firmly fixed and not be removed by force of the fingers.
Second. Check the presence of all nuts on the wheels. The nuts must be native, if a substitution has occurred, immediately call the master and bring all the fasteners in completeness.
Third. With the help of a balloon wrench, we “wrap” all the nuts again. There are many cases when a car that left a tire fitting station lost control and got into an accident due to fastening nuts not tightened properly.

We change the car on our own

Many of the motorists change seasonal tires on their own in a garage. Moreover, most operations can be carried out a couple of weeks before the replacement.

In advance, the wheels are removed from the storage place, pumped up a little more than the norm, carefully wiped with a dry, clean rag and inspected. If the condition of the rubber does not require the intervention of a specialist, he sends the wheels for balancing. Checking the wheel for imbalance should be done as regularly as possible, the frequency depends on the quality of the roads and the mileage. But in any case, when changing tires, balancing is essential.

To change wheels, special skills and knowledge are not required, it is enough to follow simple rules. After loosening the wheel nuts with a wheelbrace, install the jack in such a way that the support of the lifting part of the jack barely touches the point of application of force to the car body. As a rule, the manufacturer determines the location of the jack in the diagrams and technical descriptions to the car. The sole or base plate of the jack must rest on a dry, level surface with a hard surface. Before lifting, be sure to check that the gear lever must be set to first or reverse gear. Wooden blocks are additionally installed under the free wheels to prevent the possible movement of the machine when working with a jack.

Having lifted the wheel with the help of a jack with a separation of a couple of centimeters above the supporting surface, under the bottom of the car you need to install a reliable metal support that duplicates the jack. "Professionals", as a rule, do not do this, neglecting the safety rules. Using a wheel wrench or by hand, remove the fastening nuts and remove the wheel.

Using a lantern, they inspect the suspension elements, first of all - the absence of stains from the leakage of process fluids, the integrity of rubber covers and seals. If there are traces of rust and corrosion on the elements of the wheel hub, they must be removed with a stiff brush and the surface treated with a protective compound, or silicone spray. The latter does not apply brake discs. Usually, they additionally check the condition of the plastic or composite protection of the wing arch, the absence of cracks and damage.

If everything is in order, install the wheel with the appropriate rubber and tighten the nuts by hand until it stops. With a balloon wrench, slightly increase the torque. Now you can remove the additional support and lower the wheel.

After completing a similar procedure with all wheels, using a wheelbrace, we tighten all the nuts on the wheels one by one. At the same time, diagonally from one nut to another, increasing the tightening torque. The procedure must be performed in turn with all the wheels.

Removed wheels must be thoroughly washed with high pressure water and dried indoors. Experts recommend storing rubber in an upright position, after packing it in dark polyethylene or special covers. Properly stored quality rubber practically does not lose its properties and serves for a long time.

Motorists often change tires - either from summer to winter, then from winter to summer, then when buying new tires, then with damage and punctures. Tire replacement is usually entrusted to service stations. But, in order to save money or for other reasons, motorists can master this procedure on their own. To replace rubber with your own hands, you need a wheel wrench, a pair of mounting blades, a jack and a car pump. However, without knowing some “secrets”, it is difficult to replace a tire on your own. We'll talk about the tricks of replacing a tire now.

Removing the old tire from the rim

First you need to remove the old tire from the disk. To do this, raise the car with a jack, unscrew the fixing bolts with a wheelbrace and remove the wheel from the car. Lay the wheel on the ground with the valve up, remove the nipple from the valve and let the air out of the tube or tire (if the tire is tubeless). After that, “drown” the valve inside the tire and stand with your feet on the wheel so that the sidewalls of the tire are wrung out from the rim. Sometimes the tire "sticks" to the rim and you have to make an effort. After you managed to wring out the sidewalls, insert the mounting spatula into the gap between the rim and the sidewall of the tire. Working with two mounting blades, bring the sidewall of the tire out of the wheel rim, and pull out the chamber into the resulting gap. In the same way, bring the other sidewall of the tire through the same rim, and remove it from the disk. Be careful not to damage the disc. Particular care must be taken with a fragile alloy wheel.

Installing a new tire on a rim

Before installing a new tire on a rim, check its condition - carefully inspect it for defects and damage, make sure that the tire and rim fit each other in size. Also check the condition of the disk, for mechanical damage, the absence of dirt and rust, wear of the rim flanges. Remove the old balance weights and the old valve if the tire is tubeless.

Installing new tires, do not forget to take into account the colored marks and pointers on the tire. Namely, the recommended direction of rotation, which is usually indicated by an arrow on the sidewall of the tire. For an easier and more gentle installation of the tire, you need to apply a special lubricant or soap solution to its bead and bead heel. Don't over-lubricate or the tire will slip on the rim!

Mounting the tire on the disk is carried out in the reverse order with respect to dismantling, that is, first one sidewall is put on the rim of the disk and, if it is a tire with a chamber, then the chamber is inserted, while its valve must enter the rim hole. After that, the second sidewall of the tire is put on.

How to inflate a new tire so that it sits tightly on the rim

If the tire is chambered, then your task is very simple - inflate it with air, with a pressure slightly higher than normal, so that the tire "sits" well in place, then reduce the pressure in the tire to normal, while taking into account that the pressure must be measured, when the tire is installed on the car, that is, taking into account the weight of the car.

If the tire is tubeless, then the task is more complicated. Unfortunately, with a conventional hand or foot pump, or even car compressor it will not be possible to pump it up until the tire beads “sit” tightly on the rim, since the air will simply go out into the gap between the tire and the rim of the disc. But there is a way out!

To solve the problem, inflate any car wheel to 3.5 - 4 atm., Remove the hose from the pump, put one end of this hose (the one without a fitting) directly on the valve of the tubeless tire that has just been mounted, after removing the nipple from the valve, and put the other end of the hose, equipped with a fitting, on the “pumped” tire. At the moment of putting on the fitting, a large portion of air will enter the empty tubeless tire and "put it in place" on the disk. The beads of the tire will sit firmly on the rim, and the tire can now be inflated in the usual way. At the service station for pumping tubeless tires they use special compressors with volumetric receivers, but, as you can see, you can solve this problem yourself, at home.

Do not forget that after installation new tire wheel needs to be re-balanced.

Before mounting a tubeless tire, the wheel rim must be inspected and checked. It is recommended to check the rim profile with a special template.

There should be no dents, dirt, rust, scratches, sagging on the weld on the rim. The rim must be carefully painted. Particularly clean and even should be the shelves and flanges of the rim, mating with the tire beads.

Rust and bumps on the rim are cleaned with sandpaper or a file. Damaged paint must be restored by applying it in an even thin layer, without sagging.

Then a valve is installed on the rim, the hole for which must be clean and without burrs. The cap 13, the nut 10, the metal washer 9 and the rubber washer 8 are removed from the valve and the valve with a rubber sleeve 7 is inserted into inside rim into the hole. Then washers 8 and 9 are put on the valve and nut 10 is tightened, which ensures tight installation of the valve in the rim. Then the cap is screwed on.

Rice. Wheel with tubeless tire:
1 - wheel disk; 2 - valve; 3 - sealing layer of rubber; 4 - wheel rim; 5 - sealing layer; 6 - balancing weight; 7 - sealing sleeve; 6 - sealing washer; 9 - valve washer; 10 - nut; 11 - valve body; 12 - spool; 13 - key cap

Beads of the tire, as well as shelves and flanges of the rim, must be washed with warm soapy water before mounting the tire. The tire is mounted with extreme care. Even slight damage to the special rubber layer on the seating surface must not be allowed.

It is very important that clean and smooth mounting blades are used, with well-rounded edges. During installation, it is necessary to moisten the blades with clean water. It is necessary to refuel the tire beads onto the rim, starting from the side opposite to the valve, and then gradually approach it from both sides. At the same time, the blades are moved over short distances, no more than 100-150 mm.

A tubeless tire is difficult to inflate at first, as it is necessary to ensure that the bead of the tire is firmly seated on the flanges and flanges of the rim and that the tire retains the inflated air. Then, when the tire is under some pressure, its sides will press against the rim themselves and provide tightness.

Before inflating, raise the wheel and, while turning it, hit the ground with the tread several times so that the tire beads sit on the rim shelves. Then the spool is unscrewed from the valve and the tire is inflated with a compressor. It is difficult to inflate a tubeless tire with a hand pump, since it cannot immediately supply the necessary amount of air that would fill the tire quickly enough and tightly press its beads to the rim flanges.

The tire is inflated with a compressor to a pressure of about 1.5 kg / cm2, then the hose is removed and the valve is quickly screwed in so as not to release much air from the tire. After that, the tire is inflated with a hand pump to a pressure of 2-2.5 kg/cm3 in order to firmly seat it on the rim. If the tire beads are not yet firmly seated on the rim shelves, it is necessary, while turning the wheel, to hit it several times with the tread on the ground. After that, you should check the tightness of the tire, that is, let the wheel go into the water or, laying it flat on the ground, pour a soapy solution between the tire bead and the rim. After checking the tightness, you need to bring the tire pressure to normal 1.7 kg / cm2.

If a compressor is not available, a tubeless tire can be inflated with a hand pump using the following technique. To do this, they tie the wheel with the tire with a rope along the middle part of the tread and tighten the rope, twisting it with a stick. Due to the compression of the harmful part of the tire, its beads diverge to the sides and are pressed against the rim flanges. Instead of a rope, you can use a special steel tie-down band. If enough air has been inflated to pre-compact the tire, the rope or tape should be removed.

A tubeless tire sticks to the seating surface of the rim and is therefore more difficult to remove than a tubed tire when it is removed. For this purpose, a special shoe is attached to the driver's tool kit. The deflated wheel is placed on the ground under the car body. Then, putting the shoe on the side of the tire near the rim, they put a jack on it and, placing the paw of the jack in the socket on the body, raise the car. Under the weight of the vehicle, the bead of the tire under the shoe will move away from the rim. After that, the tire can be easily separated from the rim but the entire circumference. Turning the wheel over, in the same way separate the tire from the rim on the other side. The tire is removed from the rim with mounting blades, being careful not to damage the seating surface.

For normal operation of the car, it is periodically necessary to replace and install high-quality tires. This is an almost simple process, but not all motorists can handle it, especially for beginners.

Typically, replacement is performed for certain reasons:

serious deformation or puncture of several tires without the possibility of their repair and restoration;
heavy wear of one or more tires;
seasonal replacement summer tires for winter or vice versa.

In order to carry out competent work on replacing rubber, it is necessary to follow the recommendations and rules. Otherwise, it can lead to a wheel out on the track and a serious accident.

First of all, you need to know that the tires to be installed must comply with the overall dimensions and characteristics recommended by the car manufacturer. There may be small differences, but not more than 2%.

General properties and dimensions are indicated in the instruction manual vehicle. If these are not available, use the recommendation of the car dealer.

At the next stage, you need to find out the load index of the tire being installed, as well as speed characteristics. They should not be less than the parameters specified in the instructions from the manufacturer.

Tire changes can be made with higher index values, but not with lower requirements. Typically, indexes are indicated in the operating instructions for the car.

Next, you should analyze the characteristics of the air pressure in the tires. The indicators must be completely identical with the factory settings. Otherwise, the wheel may be severely deformed and burst when driving a passenger car.

In the event that tires are over-inflated or, conversely, have less air, this will negatively affect the stability of the vehicle and its high handling characteristics. Tire pressure indicators are indicated in the operating instructions for the car.

Now let's highlight another important rule that beginners and experienced car owners should use when installing a complete set of tires: when purchasing sets of tires, you need to make sure that the characteristics of the landing and departure of the disk correspond to the factory parameters of the vehicle.

If these properties do not match, then this will negatively affect the handling of the car and quickly lead to deformation of the car suspension. General characteristics departures and landings are specified by the tire manufacturer and the plant where the vehicles are produced.

Tire replacement due to heavy wear

On any type passenger car front tires are most often deformed, since most passenger vehicles have front drive axles. Accordingly, the rear wheels on them are subject to less wear.

Many owners often try to regularly replace the front tires, and leave the rear tires for a few more seasons.

But in this situation, every car lover should know that the absolute indicators of safe and reliable ride will only be achieved by using all 4 tires with the same tread.

Naturally, tires are expensive products and not everyone can afford to regularly replace products, especially in a complete set.

In such a situation, the installation of tires can be divided into two stages. To begin with, the front tires are replaced and after a certain period of time the rear tires are installed. However, all processes are recommended to be performed only with identical pairs of tires.

Car tire replacement in case of a serious defect

If the installation of new tires has to be done urgently due to the deformation of the old ones, then you should know a certain rule. Regardless of the model or brand of tires, the thickness of all four treads must be identical to each other.

If only one tire is damaged and cannot be repaired, at least a pair of new ones should be used.

It is possible to replace only one damaged tire only if the set is completely new and only a few hundred kilometers have been driven on it.

In this situation, the vehicle owner can purchase only one similar tire and install it instead of the damaged one, without fear of loss of control quality and safety while driving.

When a motorist managed to drive more than 1000 km, it is no longer possible to replace only one tire. The protectors wear out quickly enough, and balance will probably be lost when installing only one new one.

Installing new tires on the disc

Immediately before installing a new tire on a disk, a detailed check of its condition is required.

The disc is checked for serious defects, distortions, as well as wear on the flanges and rim. It is recommended to remove additional weights balancing the wheel and valve at the time of replacing the old rubber. This procedure is performed only in the situation when the tire does not have a chamber.

When installing a new tire, it is advisable to take into account the marking in the form of colored marks applied to its surface. They indicate the main direction of rotation in the form of an arrow on the side.

The implementation of a simpler and easier installation of a tire is directly related to the application of individual spots on its sides or the use of soapy liquid. However, do not overdo it with lubrication, as the rubber will begin to slide on the disc rim.

Installation of new rubber on the disk is carried out in the opposite direction with respect to dismantling. First you need to put the tire on one side of the disc rim, and then insert the inner tube. Moreover, the valve should fall into a small hole in the rim. The next step is to install the second sidewall of the rubber.

How to properly inflate tires for reliable rim additive

Thus, the tire is well put on the rim, after which the air pressure should be reduced to the desired parameters. Here it is important to take into account the fact that the pressure is measured at the moment when the tire is installed on the wheel, subject to the car weight.

For tubeless tyres, the process is a bit more complicated. A simple pump for pumping or a special compressor cannot be used until the rubber beads are completely leaning against the disc rim, since air actively penetrates through the gap between it and the tire.

You can use an alternative method: inflate a vehicle tire up to four atmospheres. Then we remove the hose and install one of its ends on the valve of the mounted rubber.

It is first necessary to unscrew the nipple and insert a part of the hose with a special fitting into the inflated tire.

Then, as the fitting is installed, the main part of the air will penetrate into the tubeless rubber and set it in place by stabilizing the pressure. At car service stations, original compressors with large receivers are used to inflate wheels.

However, such a task can be implemented by yourself, if you show a little skill and logic. Also, do not forget that after installing new rubber, the wheel is balanced.

Rubber on the front axle of the vehicle

Every owner and experienced motorist knows that the front tires should be changed at the very beginning. Since the car is subject to a lot of skidding when driving on worn rear tires, there is a great risk of deformation and rupture of the front wheels.

In a situation where tires burst on front wheel accidents without serious consequences can no longer be avoided.

Basically, the causes of severe wear of the front rubber are associated with maximum loads on the axle and regular turns of the steering system.

Since the front wheels are regularly subjected to severe impact and subsequently ruptured, higher demands are placed on them in terms of increased strength and reliability.

To reduce the risk of puncture and deformation, the front rubber must be changed in pairs of tires. The level of controllability of the car depends on the competent choice of tires.

We must say right away that we strongly do not recommend replacing tires on your own, because this process will not provide adequate safety on the road. You can only perform a quality tire fitting in your garage if you have a wheel balancing machine and a sufficient number of weights to help complete this balancing process. Otherwise, you obviously won’t be able to complete all the processes with high quality, the steering wheel will tap at speed, and when braking, you will feel the vibration of the entire car. Therefore, changing tires with your own hands is highly not recommended.

But situations are different. Sometimes it turns out that the tire fails on the road, but there is no spare wheel, in the trunk you can find only a tire repair kit. Some gaps cannot be repaired without removing the wheel. Sometimes we simply do not have the opportunity to use the services of tire fitting. In such cases, you can use your own strength and change the rubber.

What tools and conditions are necessary for self-replacement of rubber?

This process is quite simple if you do not complicate it with inept actions. You don't need a huge set of tools to do it. You need to immediately think about how you will inflate the wheel, because you need to gain enough pressure so that the car can be operated normally.

Also remember that the rubber and disc must be lubricated to achieve a normal assembly without any damage. Therefore, for tire fitting at home, you need a small but specific set of tools that will help you get the necessary working conditions. Get the following devices and materials to get the job done:

directly new rubber for putting on the disc;
flat mount, which will help to dismantle the old rubber and put on a new one;
soap solution for lubricating the disc and directly the edges of the rubber;
wheel inflation pump - it is desirable to have a compressor available;
about an hour of free time, if you have the skills of such work.

In the absence of skills, you will have to spend about two hours of time, because each wheel requires some attention, you should not rush in this process. It is necessary to perform a quality installation, make sure that the tire does not let air through in any place. Otherwise, you will have to contact specialists to fix the problem.

It is also necessary to work with tires carefully enough so as not to damage the rubber. You should be especially careful when pulling the tire on the wheel rim. At this point, specialists use special equipment that automatically performs the necessary work. And in the absence of such equipment, the process can somewhat harm the rubber.

The process of dismantling rubber with your own hands in a garage

First you need to jack up and securely fasten one side of the car. Make sure that the car is stable, because if you fall on an unprotected suspension, certain damage can occur. Then you need to remove the wheel by unscrewing the retaining bolts. The installation process is best done away from the car, because when doing work, some tools can fly out and damage the car body.

Next, completely deflate the wheel and use the flat longitudinal part of the mount to push on the part near the rim. It is necessary to tear off the stuck rubber from the metal rim in order to dismantle the old tire. This procedure must be carried out on both sides of the rim. Next, we perform the following actions:

we hook the edge of the rubber with a flat mount and bring it out of the rim;
support the rubber with a large screwdriver or other tool so that it does not slip back;
we take out the mount and insert it a little to the side of the screwdriver, continuing to get the rubber out of the rim;
when the first side of the rubber is freed from the disc, it is necessary to use the mount to bring the second edge out of the rim;
then with the help of your hands you can easily remove the old rubber from the disk.

Be careful when performing this task. Especially if you want to use rubber next year. First, make sure that none of the tools fly out of the rubber and shoot at the surrounding objects. Also, be careful not to tear the rubber or damage parts of it.

With the help of the mount, you can not make too much effort, otherwise such a process will end with damaged rubber. Dismantling in this case is one of the most important processes and complex tasks. Mounting new tires will be much easier and faster.

We install new tires

When the disk is free from the old tire, you can install a new tire. To do this, lubricate the extreme parts of the rim and tire with soapy water. This procedure will help to get a tighter contact and a soft shrinkage of the rubber. The installation procedure is quite simple, it will not be a big problem, however, everything must be done in accordance with the requirements. The installation process is as follows:

lubricate the rubber and rim with soapy water, place the rim in a horizontal position on a solid base;
put the rubber on top, having previously determined the direction of rotation (indicated on the side of the tire);
put one side of the tire onto the rim with your hands, and at the last point use a pry bar for mounting;
then, using the mount, alternately put on one part of the second side of the tire;
the next step is to inflate the tire, during which the tire will fall into place;
next, you should check for the absence of descent and other problems.

To inflate tires, it is better to use an automatic compressor, because a manual or foot pump will have to be used for a long time, which will increase the time spent on tire fitting too much. Remember that whenever possible, after such a replacement of tires, it is necessary to contact specialists and balance the wheels. Otherwise, the rubber will be eaten unevenly, and at high speeds you will feel certain problems with control and comfort.

Of course, our people can come up with a tire changer from an old broken column and do the procedure as follows:

Summing up

To perform an independent tire fitting, you need to have a small set of tools and a sufficient amount of free time. This is a simple procedure, it does not require certain specific skills to perform it. But you can resort to the possibility of performing this task only if you have no other way to replace rubber. This is a temporary measure that will only help to get the opportunity to operate the machine for a certain time.

After a certain period, it is necessary to contact a professional tire fitting and perform wheel balancing. Carry out this procedure with high quality specialized equipment just impossible. Therefore, it is better to give preference to specialists.

If these properties do not match, then this will negatively affect the handling of the car and quickly lead to deformation of the car suspension. General departure and landing characteristics are specified by the tire manufacturer and the factory where the vehicles are produced.

Naturally, tires are expensive products and not everyone can afford to regularly replace products, especially in a complete set.

In this situation, the vehicle owner can purchase only one similar tire and install it instead of the damaged one, without fear of loss of control quality and safety while driving.

How to change tires on a car

Spring inevitably brings warmer temperatures. For motorists, this means the need for such a procedure as replacing tires on a car, the timing of which is regulated by law in some countries.

This need is explained by the fact that seasonal tires have specific features that allow their operation only in a specific period. Using the wrong type of car tires often leads to unexpected costs. It can also cause an emergency.

Timing for replacing winter tires with summer tires

Traditionally replacement winter tires for tires for the warm season is made by the owner of the car when he considers it necessary, based on his beliefs and / or capabilities. Terms of replacing winter tires with summer tires Russian Federation does not regulate. Formally, this requirement applies only to cases of replacing studded tires with summer tires.

When should you change winter tires to summer tires?

Therefore, there is no exact period in which the mentioned procedure must be performed. Car owners have the right to engage in seasonal tire changes whenever they want. Those motorists whose cars were shod with studded tires should know that, according to the law, the period for replacing studded tires ends on June 1st. This is the deadline for replacing winter tires with summer tires in the case of studded tires.

Despite all of the above, experts recommend changing Velcro when the night temperature remains positive for several weeks. It is these conditions and temperatures that are ideal for replacing rubber.

How to change tires on a car

Changing tires is, in fact, a process that does not cause any particular difficulties. Any service center handle this task in a matter of minutes. And from a financial point of view, this service is relatively inexpensive. But there is a group of people who prefer not only to independently determine the period for replacing winter tires with summer tires, but also to do it on their own.

An example of properly lifting a car with a jack

In such a situation, there are two options for resolving the issue:

Complete wheel replacement.
Changing tires on installed rims.

Obviously, the first option will not require any specific skills or excessive efforts from the motorist. It does not take much time to carry out such manipulations and time. It is enough to have a jack, a tubular wrench and basic motorist skills.

Despite the simplicity of the procedure, even in this case, replacing rubber with summer tires must be carried out independently in compliance with safety rules. According to them, the car must be parked on a flat and firm surface. Before using the jack, the car must be installed on hand brake. The car should also be fixed additionally using special shoes for this purpose.

In the case when the surface is not hard enough, a wide board should be placed under the jack support, which will reduce the load produced by the vehicle, evenly distributing it over a large area.

Spinning the wheel before jacking up

Before the car is jacked up, the bolts on the wheels are unscrewed.
By means of a jack, the car body rises to the desired level and is fixed.
Wheels with winter tires are replaced with analogues with summer tires.
The car drops to the ground.
New wheels are fixed.

Obviously the option complete replacement wheels are very comfortable. However, not all motorists have such a replacement kit, especially in the assembly. Therefore, for them, seasonal tire replacement implies tire fitting.

Technically, tire fitting is also not a complicated procedure. But most car owners prefer to do it with the hands of service station masters. For those who are not familiar with wheel beading, we offer a step-by-step description of the process.

Tire wheel on rim

When it comes time to replace winter tires with summer tires, two blades must be prepared for tire fitting. The further process includes the following steps:

The rim is treated with soap to ensure slip.
By means of the blades, the tires are removed from seat on the wheel rim. This is not a quick and rather laborious step.
Summer tires are mounted on rims instead of winter analogues. This process is reversed.

Basic rules for changing tires

When replacing tires with summer tires becomes an urgent need, or when the deadlines for replacing rubber with winter tires expire according to the law, people begin to rush and make mistakes. The vanity is fraught with serious troubles. So, no matter what, stick to the following rules.

Mounted tires must have the characteristics and size recommended by the vehicle manufacturer, or differ by 2%.
Tires must have a load / speed index, the value of which cannot be less than that prescribed by the manufacturer of a particular vehicle. It is allowed to use rubber with large values, while with smaller values it is strictly prohibited.
The internal pressure in the tire chambers must correspond to the indicators recommended by the car manufacturer. Different values can be set for wheels of different axles.
When purchasing wheels, you should make sure that the landing diameter and offset of the disks correspond to those in the technical documentation of the vehicle manufacturer. Otherwise, this discrepancy will have a negative impact on the handling of the vehicle, as well as tire wear.

How to correctly decipher the markings on car tires is shown in the figures below.

How to change tires when they are worn out

The average daily temperature for replacing tires with winter ones, traffic regulations for the timing of replacing tires and the need to replace winter tires with summer tires according to the law are not all the reasons for changing the “shoes” of your “iron horse”.

Tire wear also requires the attention and intervention of a motorist. Tires wear unevenly. Usually the tires on the front wheels suffer more. Therefore, some drivers try to replace tires only in front, leaving the rear wheels intact for another 1-2 seasons.

Having decided on such an adventure, it should be understood that driving safety is ensured only if the entire set of wheels has the same tread pattern. Otherwise, the risk of losing control of the vehicle increases significantly.

How to tell if tires are worn out

Experts say that the greatest driving safety can only be achieved by replacing tires with winter or summer tires according to the rules, when full set four identical tires.

High-quality tires are quite expensive, and not everyone can afford a one-time change of all four tires. Then the replacement is recommended to be performed in two stages. First replace the front pair of tires, and then the rear. But you should not delay updating the latter, because old tires increase the likelihood of skidding.

How to replace tires with severe damage

If your car's tires are seriously damaged, follow the basic rule. It states that the tread thickness on all wheels should remain the same. In the event that tire retreading is contrary to this rule, you should change a pair of tires on the wheels of one axle, at least.

Typically, replacing a single tire will damage the vehicle's handling. The only exceptions are new tires or tires with low mileage. Having rubber without tread wear, you can purchase one similar model and install in place of the damaged tire.

Tire replacement options for vehicles with different drives

If the rubber has served a decent time, this solution will not help. The tread thickness on wheels on the same axle will vary markedly, dangerously increasing the chance of loss of control.

It’s not worth the risk, especially since by replacing two wheels and throwing away a damaged tire, the second one can be used as a “spare tire” or sold.

We repair a punctured tire - a test of 16 repair kits and advice from ZR

Can a punctured tire be healed with a first aid kit? Za Rulem experts tested 16 tubeless tire repair kits in the case, and at the same time demonstrated the operation algorithm to save the damaged tire. The instructions are supplemented by life hacks that will be useful to all drivers.

In ancient times, there was GOST 5170–73 “First-aid kits for repair pneumatic tires". What components were not in these first-aid kits! And a fungus, and a grater with a band-aid, and a roller ... And now each manufacturer decides for himself what exactly to put in his kit.

Let's check what the descendants of those travel kits are capable of. Pushed to decisive action editorial Grant, one of the wheels of which has expired. Instead of a tire changer, we visited several shops where we purchased 16 different tubeless tire repair kits. The spread of prices is sevenfold, although the principle of operation is the same. After detecting a puncture, you need to remove the culprit of the trouble (a self-tapping screw, a nail), then expand the hole and firmly insert a folded rubber flagellum into it. The nuances of technology and tools may vary, but in general, the repair algorithm is exactly the same.

Having repaired the tire, which met the self-tapping screw on the road, we decided to test all 16 repair kits on the poor thing. However, in the end, only 13 stab wounds were inflicted on her, since three sets were rejected at once: the flagella in them are frankly bad, instantly torn in the hands.

The instruments also differ quite a lot. So, the cute handle in the CityUp CA-793 set managed to turn around relative to the sting at the first attempt to get inside the tire.

Note that in some sets there are no “pickers” provided, and in some places there is no glue. And the names of the instruments are different for almost all manufacturers - in the explanations we give exactly the “branded” version.

A tire with so many holes in the tread part passed the test of running at speeds of over a hundred for a couple of weeks without losing a drop of precious air. For the sake of the experiment, we did not even cut off a few ponytails - and everyone resisted. A small puncture in the sidewall was also managed with the help of a flagellum. Although the reliability of sealing is noticeably lower than in the case when the tourniquet is held in a thick (even for a used tire) tread layer.

Towards the end, another test was carried out - a kind of "household" one: they pierced the sidewall of the tire, like some kind of bully with a knife or a screwdriver. We were no longer engaged in comparative tests, but simply fought for survivability. By the way, the same damage occurs, for example, when the tire makes hard contact with a curb or a sharp edge of a pit. Such a temporary repair is a priori more difficult: the sidewall is thinner than the tread, and therefore it is more difficult for the flagellum to stay in the hole.

Approximate price: 180 rub.

Equipment: spiral awl, tool for installing harnesses, raw rubber strips (5 pieces),
adhesive activator

The spiral awl destroys the cord - when installed, a crackling of tearing threads is heard. However, the repaired wheel drives successfully.

Approximate price: 200 rub.

Equipment: a tool for stripping and forming a hole, an awl with an eye, reinforced plaits (5 pieces), glue

The beautiful handle of the rasp turned right away - the set can be removed from the tests. Okay, we took an analogue of a “picker” from another set ... As a result, the wheel was repaired, but it’s hard to advise buying such a first-aid kit.

Approximate price: 540 rub.

Equipment: Twisted tip tool, eye tool, raw rubber activator adhesive, raw rubber strips (8 pieces), cutter

The spiral awl is good, the handles are comfortable. Note the presence of a cutter in the kit - it is not in other kits. I liked the first aid kit, but it's pricey.

Approximate price: 330 rub.

Equipment: tool with a twisted tip, a tool with an eye, an activator adhesive for raw rubber, raw rubber flagella (3 pieces)

I didn’t like the picker: the cord breaks. But the wheel was still fixed.

Approximate price: 160 rub.

Equipment: twisted tip tool, eye tool, wet rubber activator adhesive, plaits (5 pcs)

A tool with a hole like the eye of a needle has a too wide groove. Nevertheless, the set has stood the test.

Approximate price: 130 rub.

Equipment: a tool for stripping and forming a hole, an awl with an eyelet for installing a tourniquet, reinforced cords (5 pieces), glue

The inexpensive kit coped with the task successfully, demonstrating the best value for money.

Approximate price: 100 rub.

Equipment: rasp for cleaning and forming a hole, awl with an eye, reinforced braids (5 pieces), glue

The handle is poorly made.
The glue feels very watery. However, it works.

Approximate price: 220 rub.

Equipment: lug tool, wet rubber activator adhesive, conical black plugs (6 pieces)

Stepped "wedges" broke almost immediately. Failed.

Approximate price: 300 rub.

Equipment: eye tool, raw rubber strips (10 pieces), activator glue

The set failed rather quickly: weak, unreinforced strips of raw rubber tore at the first attempt to push them with the supplied tool onto workplace. Failed!

Approximate price: 720 rub.

Equipment: pressure gauge, rasp, eye tool, repair harnesses (10 pieces), glue, 4 caps, 4 spools, universal key for cleaning valve threads, 10 chamber patches

The most expensive, but also the most complete set in our selection. The kit coped with the puncture. However, the tool is inconvenient. And most of the content will not be needed by everyone.

Approximate price: 180 rub.

Equipment: rasp, needle tool, repair strips (3 pieces), glue

Glue is liquid, like water. But the wheel was repaired pretty quickly.

Approximate price: 175 rub.

Equipment: tool for stripping and forming a hole, an awl with an eye for harnesses, harnesses for repairs (5 pieces)

There is no glue included. However, the set fulfilled its immediate function.

Approximate price: 270 rub.

Equipment: eye tool, long black "self-vulcanizing" cords (4 pieces)

Glue is not included in the kit. The straps appear to be very thin. There is no tool for preparing the hole in the kit - you have to act immediately with a “needle”. However, we completed the sealing of the hole.

Approximate price: 270 rub.

Equipment: lug tool, wet rubber activator adhesive, conical red plugs (6 pieces)

Red step-shaped "gags" are torn even before they are installed in the tire.
Failed.

Approximate price: 150 rub.

Equipment: spiral file, awl with eye, plaits (3 pieces), glue

Inexpensive set successfully coped with the task.

Approximate price: 240 rub.

Equipment: file tip tool, eye tool, raw rubber bands (5 pieces), activator glue

The sting of the “picking” tool is too thin. But the wheel was repaired.

Of the listed kits, we select Titan T‑609 for 130 rubles - with affordable price it is equipped with a set of tools that did not cause any complaints from us.

Separately, we note DoneDeal DD0320 for 540 rubles - the only set in which a cutter is provided to cut off the ends of the bundles sticking out of the tire. If not for the price, he would be a champion.

ALGORITHM FOR REPAIRING A TUBELESS TIRE

We determine the place of the puncture. If an external examination does not help, immerse the wheel in water or, at worst, douse it with water to detect air bubbles. Sometimes for this you need to increase the pressure to 2-3 bar. Having found a puncture, we mark it. Pliers extract the culprit.

We take a tool for stripping and holes (colloquially - a “picker”), install it in the puncture site and release the handle - we are trying to determine the direction of the puncture by the angle of inclination.

We apply a layer of glue to the surface of the “picker” (if it is present in the repair kit) and first screw it all the way into the tire, and then pull it out. The operation must be repeated two or three times. On the last pass, leave the tool in the recessed position.

We take a tourniquet and install it in the eye of an awl (it is also called a “needle”). We apply glue to the surface of the bundle.

We take out the tool for stripping and shaping and quickly drive an awl with a tourniquet into the hole. The ends of the bundle must remain on the surface.

We take out the awl - the tourniquet should remain in the hole.

The tire is the same, inside view. Captured with a hidden camera...

We inflate the wheel and check the tightness with water or at least by ear.

We cut off the ends of the bundle protruding from the outside flush with the surface of the tire tread.

Everything, you can go!

Use only "classic" flagella reinforced with synthetic threads. Outwardly, they resemble a twisted rope impregnated with a rubber-like composition. Do not use any conical plugs or strips without reinforcement, otherwise you will cry.
It is advisable to choose a "picker" with a T-shaped handle. Otherwise, calluses are guaranteed.
We do not recommend using sharp, rasp cleaners for repairs. They almost always break the cord.
Before starting repairs, the wheel must be pumped up to at least 0.5–1.0 bar.
If you are in doubt about the quality of your repair, move the repaired wheel back.
If a puncture is discovered while driving, and immediate repair is not possible, do not rush to remove a nail or self-tapping screw sticking out of the tire. As long as it is in place, the tire will not deflate as quickly. Better time pump up a punctured wheel from time to time until the start of a full repair.
Remember that with the presence of glue in the kit, the installation of the flagellum becomes easier, and the chances of a long service life are higher.
If the kit has been lying in the trunk for a long time and the glue has dried up, you can use gasoline instead (but not diesel fuel).

We wish everyone that our advice will never come in handy! Have a good trip!

How to replace a tire yourself

Removing the old tire from the rim

Installing a new tire on a rim

When installing new tires, do not forget to take into account the color marks and pointers on the tire. Namely, the recommended direction of rotation, which is usually indicated by an arrow on the sidewall of the tire. For an easier and more gentle installation of the tire, you need to apply a special lubricant or soap solution to its bead and bead heel. Don't over-lubricate or the tire will slip on the rim!

How to inflate a new tire so that it sits tightly on the rim

If the tire is tubeless, then the task is more complicated. Unfortunately, it will not be possible to inflate it with a conventional hand or foot pump, or even a car compressor, until the tire beads “sit” tightly on the rim, since the air will simply go out into the gap between the tire and the rim of the disk. But there is a way out!

To solve the problem, inflate any car wheel to 3.5 - 4 atm., Remove the hose from the pump, put one end of this hose (the one without a fitting) directly on the valve of the tubeless tire that has just been mounted, after removing the nipple from the valve, and put the other end of the hose, equipped with a fitting, on the “pumped” tire. At the moment of putting on the fitting, a large portion of air will enter the empty tubeless tire and "put it in place" on the disk. The beads of the tire will sit firmly on the rim, and the tire can now be inflated in the usual way. At service stations, special compressors with volumetric receivers are used to inflate tubeless tires, but, as you can see, you can solve this problem yourself, at home.

Do not forget that after installing a new tire, the wheel must be re-balanced.

Car tires play an important role in the operation of the vehicle. They provide comfort while driving, make the movement in the car safe, provide reliable traction in adverse weather conditions. And the first thing to remember for both a novice and an experienced motorist is the need to control the level of tire pressure.

Why is it so important? It is the pressure indicators that determine the readiness of the wheel for road confrontation in all weather conditions. Thus, a decrease in tire pressure leads to an increase in fuel consumption. And in a critical situation, it can cause loss of controllability and stability of the vehicle. So is it worth the risk if regular tire pressure checks will allow you to avoid a lot of troubles associated with the operation of the car?

Tire device: design features and types of tires

Before mastering the wisdom of tire fitting with your own hands - in a garage or outdoors, it is important to study the theoretical part of the process. To begin with, it is worth deciding on the complete set of an automobile wheel, consisting of a tire and a disk with a rim on which it is put on.

All types of modern car tires are divided into several categories with their own design features:

In addition, tires are divided into:

highway or summer, are used for operation on a hard surface in wet or dry weather. Not applicable for operation at low temperatures;
winter, the tread of which is designed to quickly remove snow and dirt from the area of the contact patch, which ensures the grip of the vehicle with the road surface. These tires were originally designed to work in winter period and contain components that protect rubber compound from loss operational properties at low temperatures;
all season, allowing you to ensure safe driving in any weather and regardless of temperature changes.

Car tires are graded according to the type of arrangement of threads in the cord base. It can be radial - at a right angle relative to the sides, or diagonal, with threads crossing from sidewall to sidewall diagonally.

Mounting and dismantling of the wheel

Ability to dismantle and install a car wheel - great advantage for the car owner. You can be calm in the most non-standard traffic situation, and in the conditions of an urgent seasonal tire change. And if you have not yet mastered all the wisdom of automaking, it is never too late to take the first steps in the right direction. The main thing is to learn the procedure.

To dismantle / install a car wheel, you will need:

a flat area that allows you to freely change the wheels;
jack - to provide free access to the wheel mounting area;
balloon wrench right size- for dismantling.

After completing the preparations, you need to proceed in stages:

First you need to securely fix the vehicle in place, using for this parking brake(pulling the lever). The car is put into first gear. To securely fix the vehicle, it makes sense to use special devices ("shoes").
Having fixed the car, it is necessary to “break off” the wheel nuts that are subject to the dismantling procedure. To do this, loosen the nuts with a wheelbrace without removing them completely.
Next, the car should be installed on a jack, lifting it in the area where the wheel to be removed is located.
After securely fixing the vehicle on the jack, you can proceed to dismantling by unscrewing the wheel nuts and removing the wheel from the axle.

The dismantled wheel must be replaced with a spare. To do this, a pre-prepared "reserve" is placed at the place of "landing" of the wheel, installing it with the help of studs or guides - depending on the design. And then they are fixed (not completely) with the help of previously dismantled fasteners, checking the reliability of fixation (the nuts must be screwed in order of priority, starting from the topmost, in a diagonal sequence - this ensures proper centering).

The final tightening of the nuts is carried out only after the vehicle is lowered from the jack. Upon completion of the installation procedure, it is necessary to check the tire pressure (normally it should be from 2 Bar or more) and, if necessary, bring its indicators to the desired values.

Tire replacement

Sometimes the tire fitting procedure requires not just temporary troubleshooting by replacing the wheel, but much more decisive action. In particular, replacing a tire on a car disk, which even in a garage does not look like a simple matter. What will be required for self replacement tires?

Special tools - spatulas, or, for lack of a better one, two flat-tip screwdrivers.
Soap solution.

Do-it-yourself wheel beading is a process that requires a certain amount of endurance. It is necessary to separate the tire from the rim as carefully as possible, gradually pressing the rim. With paddles between the rim and tire, use the soap solution as a kind of lubricant, making it easier to release the tire bead from under the rim.

It is important to consider that you need to act slowly during the dismantling process, gradually moving along the rim. On average, in the absence of special equipment and skills, it will take about 30-40 minutes to dismantle one tire.

The tire replacement process is the same. With the help of the blades, the tire is gradually placed in place, gently tucking under the wheel rim.

Upon completion of the tire mounting process, our wheel is ready to be installed on the car. To do this, it is placed at the attachment point and fixed with bolts, and then removed from the jack and the maximum fixation of the fasteners in the mounting sockets is carried out. Upon completion of installation, the tire pressure must be brought to standard values.

We bring to your attention a video lesson "How to change a wheel on a car":

Having mastered basic fundamentals do-it-yourself tire fitting, you can always cope with an emergency tire change in driving situations without resorting to the help of specialists, but seasonal replacement summer tires for winter will not cause serious problems.
