A tire is a rubber hard jacket mounted on a disc frame. It is in direct contact with the road, therefore it is subject to rapid wear. The expiration date of tires for a car must be able to determine quickly and correctly.

Modern tires use more than just rubber. This is a high-tech product consisting of 200 different elements: plasticizer, elastomer and other chemical components.

Date of manufacture

The date of manufacture of the tire is indicated in the identification number. It is placed in an oval-shaped recess, consists of 4 digits. The first two are the week, the second two are the year of manufacture.

Each tire has a label. Its decoding will not provide much difficulty if you carefully study the order of designations. Here is the information that is usually provided:

• type of tires or their type - chamber, tubeless;
• size, including data on width, height and diameter;
• load indicator;
• manufacturer's brand - information about the brand is indicated in large Latin letters;
• seasonality data - winter, summer, all-season;
• speed index;
• date of manufacture - a four-digit code, for example, 1016, which means the 10th week of 2016;
• weather conditions - an image in the form of an umbrella, etc.

Since 2000, the age of the tire has been indicated on the tread in an oval-shaped recess. Prior to this, the year of production was marked only by the last digits of the identification code.

Tire life

Thanks to tires, a safe coupling of the car with the road and effective braking are created. For this reason Special attention the motorist must pay attention to the resource of products. Car tires or truck tends to wear out over time. It is necessary to be able to correctly determine the suitability of the product in order to carry out timely replacement.

Until 2000, any tires were considered worn after 10 years of operation. Today, the admissible shelf life of tires is marked by experts with 45,000 kilometers of a vehicle. The life of the wheels prolongs compliance with traffic rules - careful driving, seasonality, etc.

It is impossible to predict the duration of operation, since everything is individual. Driving speed, driving style, climatic conditions - these parameters are not the same. Therefore, it is recommended to periodically inspect the wheels, to identify defects even at the stage of their appearance. After 5 years of operation, tire diagnostics must be carried out once a year. And rightly so, because the older the tire, the more it is subject to changes and defects.

A crack in the tire should alert the owner. Such a tire must be shown to a specialist in order to determine the suitability of the product.

Here is what you should pay attention to first of all:

• pressure indicator;
• appearance;
• the presence of noise or unusual behavior of the car on the road (steering to the side for no reason).

You also need to check spare wheel even if it hasn't been applied. Due to incorrect storage, the rubber material of the tire may become cracked.

Service life of summer tires

Summer tires are made with a harder tread. Therefore, the duration of their operation is somewhat longer. They are able to withstand 10 years, subject to high-quality road surfaces. Their resource is highly dependent on driving style. Frequent hard braking is the cause of ametrical abrasion of the rubber and damage.

If the tread height of the summer tire is less than 1.6 mm, then it is not worth pulling with the replacement. It will be possible to measure the tread size using a special tool - a tire depth gauge.

Service life of winter tires

The shelf life of winter tires is 7 years, but in Russian conditions it rarely exceeds 4 years. It is noteworthy that the service life of winter tires is also determined by the manufacturing country:

• Russian spikes and Velcro serve less - 20-30 thousand km;
• European twice as many - 50-60 thousand km.

In addition, here are the factors that directly affect the service life of winter studded tires:

• date of manufacture;
• storage method at the base - tires must be properly stored between seasons so that microcracks do not form on the rubber;
• tire pressure - in winter it should not be excessive, otherwise the shelf life of rubber for cars will be noticeably reduced;
• the speed of the car - the lower it is, the longer the shelf life winter tires;
• overloading the trunk - reduces the life of winter tires by 20-30 percent;
• elevated asphalt temperature - you should not delay the replacement of rubber in the spring;
• wheel alignment and balancing.

Measurement of the tread height on winter tires should show at least 4 mm.

The maximum period of use of winter tires should not exceed 7 years. Studs must be stored properly, otherwise they will quickly deteriorate.

How to extend the period of use of tires

Several useful tips help extend the shelf life car tires:

1. Rubber must be properly stored;
2. Wheels need to be changed. So, on rear-wheel drive cars, the front tires wear out more slowly. If you change the location of the wheels every 8-10 thousand km, the treads will wear out evenly;
3. Check tire pressure as often as possible. It must correspond to the season and other requirements;
4. Inspect tires regularly for defects. If you find the slightest crack, immediately contact a specialist;
5. Drive calmly, try not to press the pedals sharply, always keep the car under control;
6. Maintain cleanliness. Before placing the tire in storage, stones and dirt should be removed from the tread. And even better, rinse with detergent, without using a spray bottle.

Proper tire storage

Rubber should be stored in a cool place, away from ultraviolet radiation. There should be no working generators, transformers and other electrical equipment near the tires.

Every year, due to improper storage, many tires are thrown into the trash. Not everyone knows how to properly maintain them. It's best to store them without disks:

1. It is necessary to carefully remove the rubber, rinse and dry;
2. After that, treat with a solution with preservative properties - sold in a car shop;
3. Then the tire should be put in a dark plastic bag and placed in the pantry.

It is impossible to close the bag hermetically, otherwise it will lead to the formation of condensate.

Warranty period for tires

A tire wears out easily, whether it has been used or not. Over time, the rubber oxidizes, cracks form on the edges, and the traction parameters deteriorate.

The service life of new car tires is limited to 5-7 years. As for old rubber, manufacturers do not recommend using products that have been in the warehouse for more than 10 years. They just lose their warranty.

List of TOP 10 popular rubber manufacturers

There are a lot of tire manufacturers today. Rubber of each company has its own characteristics. Here is a list of the top 10 brands:

1. Bridgestone. Japanese stamp, which has maintained its leadership in tire production since 2007. Bridgestone supplies sports cars with its tires;
2. Michelin. The second concern in the world. Today, Michelin opens factories in our country;
3. goodyear. Euro holding, which includes several companies;
4. Continental. Manufacturer of premium tires for passenger cars;

8. Yokohama. Classic, Japanese tire manufacturer;
9. Nokian Hakkapeliitta. Best Brand winter tires from Finland;
10. Kumho. Korean tire brand, which produces economy and premium models.

Michelin Alpian winter tires have a directional tread pattern. They are best suited for wet surfaces and melted snow, but they should not be used in severe ice conditions.

Shelf life of car tires in stock

GOST - state standard, regulations of the Ministry of Transport for the safe storage of tires. There are GOSTs 4754-97, 3112199-1085-02 and 24779-81. According to these legislative documents, the tire storage standard should not be exceeded. Then, according to the law, the rubber must go into operation. However, tires do not last long in stores and warehouses - they are sold out.

Products will retain their original characteristics for as long as possible if the following conditions are met:

• the presence of spacious rooms, closed from sunlight;
• safety standards at height;
• preserved temperature regime- from -30 to +35, low humidity.

Car tires are important to be able to properly operate and store. This will save the budget, improve driving safety.

Tires are one of the most important parts of a car because the rubber is in contact with the road surface. This means that this data wears out much faster than all other components of the car. Manufacturers claim an average service life of 7-10 years. But given the imperfect quality of the roads in many places, the rubber is unlikely to last that long, and it will not be possible to accurately calculate the wear resistance. Therefore, experts recommend inspecting tires for wear every 3-4 years, so as not to get into trouble if the rubber suddenly fails on the way.

The main factors affecting the life of a tire:

New tire

• Conditions and driving style. High speed, poor quality road surface, uneven movement greatly reduce the life of tires. At high speed rubber wears out almost twice as fast as with the average.
• Overloads. When exceeding maximum load on the wheel specified in the index, the service life of the rubber passenger car becomes much smaller.
• Tire pressure. If the tire pressure level is lower than recommended by the manufacturer, their service life is significantly reduced.
• Blows. When rubber collides with something, also when driving on poor quality road surfaces, the tread can be damaged, which, of course, greatly reduces its shelf life.
• Temperature. The discrepancy between the recommended by the manufacturer and the actual ambient temperature also affects the life and quality of rubber operation.
• Wheel location. If you place the tires on the same axle in the following way (the old tire is opposite the old one, the new one is opposite the new one), this will help extend the life of the rubber.

Service life according to GOST

Overloaded car

To begin with, it is worth clarifying that the service life of car tires, according to the law, is the period during which the manufacturer of the wheels is responsible for their product and for possible inconveniences associated with it. In Russia, a guarantee for tires is established for a period of 5 years from the date of manufacture. But in Western countries, this period is a service life of 10 years.

On a note!

It is worth noting that nowhere in the world is it required to change tires when the service life comes to an end. But it is obvious that there are certain risks associated with the use of such car tires, so, of course, it is worth checking the tire for wear and replacing it in case of extreme damage to ensure comfort and safe driving. vehicle.

How to extend the service life with your own hands

To begin with, in order to extend the life of the rubber, it must be correctly balanced and installed in a tire service. Otherwise, incorrect installation will cause uneven wear which sooner or later will lead to some damage.

It is worth noting that the correct adjustment of the wheel alignment angles, otherwise called "alignment", is incredibly important. This process needs to be done every year. In addition, the condition of the suspension itself has a direct impact on the wear resistance of tires.

It is incredibly important to monitor the pressure in the chambers. If possible, check your blood pressure every two weeks. Before a long trip, it will not be superfluous to make sure that the parameter corresponds to the recommended one.

It is necessary to check the pressure after installing a trailer or loading a large amount of luggage into the car. Often the car manufacturer specifies recommended pressures for various loads. Following this indicator, the driver greatly reduces the threat of damage to tires and increases their wear resistance, the life of the rubber. In addition, with regular checking and adjusting the pressure in the tires, fuel consumption is somewhat reduced, which is a big plus.

To increase the service life of rubber, certain storage conditions must be observed:

• When storing tires, it is worth setting the pressure level 0.5 bar higher than recommended by the manufacturer.
• Wheels should only be stored in a dry and clean place out of direct sunlight.
• The storage area must be well ventilated.
• It does not hurt to use special wheel care products.

When storing, you need to comply with many conditions, but this pays off with a long shelf life.

Half flat tire

Even a simple wheel wash can extend their life. It is important to do this regularly and correctly. It is necessary to use a brush and a special tool for tires.

Note!

It is extremely dangerous to wash the wheels if the water pressure exceeds 100 bar, and if the wheels are located close to the body arches, then this is all the more not worth doing. The fact is that under such pressure, water can damage the tread, which will clearly reduce the service life and safety.

In order to use tires as long as possible, it is worth monitoring your driving style. In such a situation, it is preferable to drive calmly and carefully. For example, braking has a significant effect on the tread - the sharper the braking, the worse the condition of the rubber. In addition, sharp maneuvers reduce the life of the rubber. Don't make sharp turns for no particular reason.

Obviously, the condition of the roads also affects both the tires in general and their useful life. If the road surface leaves much to be desired, the life of the tire will, of course, be shorter than with a good asphalt road. Also, do not partially drive on the curbs - this causes damage to the wheel frame and shortens its service life. When driving on bad roads, check the tires more often for possible damage.

Shelf life in the warehouse

As noted above, the shelf life in Russia is 5 years, in Western countries - 10.

But if the storage conditions are not observed, the wheels will be unusable after a very short period of time. There are several conditions that must be observed so that a tire stored in a warehouse does not become unusable.

Warehouse storage option

Taking into account the fact that tires are made of rubber, we can draw the following conclusions: they are harmed by direct exposure to sunlight, high temperature and humidity. Although the tread itself will not be damaged, the tire can suffer greatly from the action of these factors.

For proper storage of rubber, professionals recommend following several rules that help save rubber:

• Be sure to keep your tires in a clean, low-humidity area out of direct sunlight. In addition, it is important to ensure that the temperature in this room is not higher than 25 ° C, and that this room is closed. In principle, tires can be stored outdoors, but not more than a month. In the unstable Russian climate, this way of storing tires can greatly reduce the life of the tires. In turn, such factors are easily controlled indoors.
• Tires must be stored vertically. It is strongly not recommended to store tires in a suspended position - this will only harm them. It is best to store rubber on a flat surface, and a semi-circular surface is ideal, as it deforms the tires less. When using a cable or something thin, the load on certain parts of the rubber increases, deforming them.
• When tires are stored for a long time, it is important to change their footprint by turning every few months. This will help avoid tire imbalance and sidewall and tread deformation.
• If tires with missing rims are stored in a pile, this is extremely bad. Under the weight of the tires located at the top, the shape of the tread of those below them will change. With such exposure for more than 3 months, the tread profile will change. By installing such a tire on a car, the driver provokes a deterioration in grip and a decrease in the contact patch, which will lead to incredible wear of the central part of the tread. Increases the risk of tire damage.
• It is highly not recommended to store tires in the same room with oil products, various chemical products and similar composition - this may affect the characteristics of the rubber for the worse.
• When storing the tire with the tubes, it is better to reduce the pressure to the minimum in order to avoid subsequent deformation. Separate chambers also need to be pumped up a little and stored somewhere on a semicircular surface.
• When storing tires together with disks, it is better to do this in stacks of 4 pieces, with a pressure not higher than 1.4 atm. Tires should be on as flat a surface as possible. In addition, in this case, it is not forbidden to store the tires suspended, provided that the cable is attached to the disc.

Stack storage

As you can see, the shelf life of tires for cars can vary greatly. Of course, under all conditions, the shelf life of tires in the warehouse can be very long, but it is extremely difficult to find samples that have lain in the warehouse in compliance with all such conditions. It is important to remember that the life of a car's tires can be greatly extended by observing the conditions listed in this material. By following the rules for operating and caring for tires, you can postpone the purchase of new expensive models, saving significantly.

What is the shelf life of car tires?

When buying a new car tire, a car enthusiast is interested in several questions:

• How long has the tire been in storage?
• when was it released;
• How long can this set of tires last?

Answers to all these questions are available in GOST - the state standard ..

Shelf life of car tires in stock

There are two important documents regulating the shelf life of tires in warehouses, as well as the necessary conditions that must be created for this:

• GOST 4754-97;
• GOST 24779-81.

According to these documents, the maximum storage period is 5 years. However, this does not mean that after five years after the production of rubber, it is unusable. The consumer himself determines suitability at his own discretion.

Tire shops and warehouses usually don't keep tires that long as they are either taken apart or sent back to the factory for recycling. Various promotions are also often held and expired tires can be bought at a reduced price.

Even 5 years after release, the tire is serviceable if it has been stored in the right conditions. We have already given this question on the site site, but we will repeat it again.

The following conditions must be created in the warehouse:

• darkened spacious rooms;
• all safety standards are observed;
• no direct sunlight;
• air temperature is allowed in the range from -30 to +35, but the optimal performance is + 10- + 20 degrees;
• humidity - not higher than 80 percent.

It is also very important that the rubber does not lie in piles all this time or is not suspended on hooks. From time to time it needs to be translated. If you find deformations, small cracks or swollen areas on the sidewalls, this indicates that the tires were stored incorrectly.

Date of manufacture

According to article 12.5 of the Code of Administrative Offenses, a fine of 500 rubles is provided for driving on “bald” tires. If the residual tread height is less than 1.6 mm, then it is prohibited to drive on it. Accordingly, tire life is the time until which the tread wears down to the TWI marker.

Naturally, as the operation progresses, other problems may emerge:

• punctures;
• the appearance of bubbles;
• cracks and cuts on the sidewalls;
• delamination.

This may be due both to the quality of the tires themselves, and to the individual characteristics of driving a vehicle. By adhering to optimal driving conditions and vehicle operation rules, you can extend the life of your tires.

How to extend the life of tires?

If you like to prove your driving skills to yourself and others: a sharp start with slippage, drifting on city highways, braking at high speeds, and so on, then the rubber is unlikely to last too long.

In order for the tires to move away as long as possible, it is necessary to adhere to the well-known rules:

• avoid aggressive driving practices;
• drive on high-quality road surfaces, go around pits and bumps;
• regularly check the level of air pressure in tires;
• switch from winter tires to summer tires in a timely manner;
• store your tires properly.

For example, there is a long-standing misconception that tires need to be lowered a little in winter in order to increase the contact patch with the surface. On the one hand, handling improves, but the tires are more likely to become unusable.

Small cracks on the sides are a sign of aging rubber. It is not necessary to immediately go to the tire fitting, but monitor the condition of the tires more carefully. Also keep an eye on the condition of the spare tire or dokatka. It is also advisable to buy sets of patches for rubber and a special automotive sealant.

The high tread height of the new winter tire pleases the eye of the car owner. At first glance, it seems that the service life of winter tires will be long. However, in practice this does not always work out. What affects the duration of use and the degree of wear of a winter tire - each driver must answer for himself.

Tire life - what to build on

When determining the service life of winter tires, the time when operation is possible and safe, taking into account the requirements of traffic rules and manufacturer's recommendations, is taken into account.

In most cases, the manufacturer stipulates the physical suitability of the product, or legally this figure is taken equal to 10 years.
The practice of operating winter tires shows that the deadlines do not always coincide with reality. For winter tires of various manufacturers, according to reviews, in Russia, the average service life is:

1. European manufacturers. Mileage taking into account different models is in the range of 50-60 thousand km.
2. Russian manufacturers. Many models are licensed, or own developments whose quality has improved. Mileage is from 40 thousand km and above.
3. Tires from China. On average, with average functional characteristics, tires show good wear resistance. There are known cases of mileage on one set of up to 80 thousand kilometers.

Car owners at the stage of choosing a set of wheels - studded tires or Velcro, should take into account that the duration of use does not exceed several seasons or 30 thousand km. This is due to increased wear of the protruding elements.

Factors affecting wear

Along with the mileage and quality of the product itself, there are also a number of operational factors that directly or indirectly affect the service life of winter studded tires. Factors should be taken into account both at the stage of purchasing a set of tires, and during the entire shelf life.

Date of manufacture and method of storage

The release date of the tire is marked for more than 10 years, and is presented on the sidewall of the tire in the form of a 4-digit code. The first pair of digits indicates the week from the beginning of the year, and the second two indicate the last digits of the year. You should not pay attention to new wheels that have been in the warehouse for more than 3 years.

A significant influence on the aging of winter tires has a long period of storage in the off-season. Ideal conditions will be a room without significant fluctuations in temperature, excessive humidity. When choosing a storage method, the following options are not allowed:

• edge storage, which leads to loss of shape;
• stacking, which leads to "flattening" of the wheels;
• hanging a tire without a rim, which causes stretching into an "egg".

The best option for storage is to hang the tire, dressed on the disk, by the metal rim. If it is impossible to independently organize this method, you should contact a specialized service that provides such a service.

Operating conditions

Significantly reduce the period of operation and some regular factors affecting tires:

1. Mileage. It is clear that with increasing mileage, the tread wears out. But even long periods of downtime have a devastating effect on the wheel. Therefore, it is important to choose a rational middle ground between frequent trips and a rare departure of a car.
2. Tire pressure. Initially, in winter, increase the value by 0.2 bar in relation to manufacturer auto. A reduced pressure of 0.5 atmospheres reduces the service life by 20%, and an even lower value becomes not only ruinous, but also dangerous. Equalize the pressure between the tires immediately!
3. Driving under load. With a constant full load of the car, even the best winter tires.
4. Operating parameters. Wheel balance should be checked at least once a year - for example, before the start of the season. As necessary, diagnose the condition of the camber angles, the condition of the suspension - this will also reduce tread wear.

The increased temperature of the road surface significantly increases the wear of the tread of winter tires. Remember that the operation of studded tires on clean asphalt. Therefore, the rules must be strictly observed. traffic by timely changing tires.

Driving style and road conditions

Long-term tests of the operation of winter tires have shown that for conditions winter roads driving at a speed of 120 km/h results in complete wear and tear 40% faster than measured driving at speeds up to 90 km/h. Do not forget that speed directly affects the flying spikes. Although recently the fastening of the spikes has become more reliable.

High speed should be correlated with the condition of the roads. Here it is easy to deduce winter wheel out of order in an instant. Do not forget that the condition of winter roads is much inferior to coverage in summer.

Operation when the degree of wear is exceeded

Many car owners are aware of the residual wear rate set for winter tires - 4 mm. That is why, when this value is reached, the operation of such wheels in the warm season continues.

Tire tests show that even after a year of operation, the braking properties of tires are reduced by 10%. And almost bald winter tires on summer asphalt are simply unsafe. The risk of a road accident increases many times over.

Many motorists do not think about the expiration date of tires, following only residual height protector. "Snowdrops", who operate the car exclusively from the thaw to the first frost, or those who use the car only for trips to the country, even consider tires to be almost eternal, since the tread does not have time to wear out. Is it really? Do tires have an expiration date?

Tire expiration date

GOST defines guarantee period tire service five years. The further fate of the tire is determined by the car owner himself, based on its condition. Some tire manufacturers give a ten-year warranty on their products, but this is more of an exception than the rule - tires usually last five to six years.

Why is the tire considered “damaged” after this period, even if the tread has not yet worn out, and there are no cuts and hernias on the tire?

Over time, the rubber ages, oxidizes, becomes more brittle, microcracks appear on it, albeit invisible to the eye, but affecting the characteristics. Consequently, the reliability of tires is significantly reduced. And this applies not only to those tires that were actively used, but also to those that lay peacefully in the warehouse, waiting in the wings. Therefore, in the name of safety, it is worth stopping the operation of tires after five to six years.

Tire production date

It is important to remember that the tires that you install on your car may well be from different parties and with different production dates. It will not affect the behavior of the car in any way. However, you still need to pay attention to the date of manufacture of tires in order to replace the aged ones in time. This tip will come in handy when purchasing both new and used tires. By checking the production date, you can protect yourself from buying old rubber, which will quickly become unusable.

In order not to get into trouble and not to buy an “expired” tire, you need to check the date of its production when buying. This date, in the form of four digits, the first two of which indicate the week and the second two the year, is indicated on the sidewall of the tire. That is, the code "3112" means that the tire was released in the thirty-first week of 2012.

How to extend the life of your tires

And what is required so that the tires do not age prematurely? The most important thing is proper storage. Tires must be protected from direct sunlight and moisture and not exposed to excessively high or low temperatures.

If you store seasonal tires mounted on a rim, it's best to hang them or stack them one on top of the other, not vertically. Tires without rims, on the contrary, are best stored vertically, but they cannot be hung or stacked. Compliance with these simple rules will avoid tire deformation, prevent rubber from cracking and retain all the properties of tires.

How not to get into trouble when buying?

Tires should be purchased from authorized dealers who comply with the storage conditions prescribed by the standards. Otherwise, there is a risk of buying tires, although new, but already affected by improper storage. Alas, it is not uncommon for rubber to lie somewhere in the backyard, open to all winds and the bright sun, before it goes to the store counter. So such savings at best result in the forced purchase of new tires in just a season, or even puts your safety at risk.

The best solution would be to purchase tires from among modern models no older than four years - in this case, you will definitely buy a quality product and enjoy the purchase. Tires are your best bet. famous brands: their quality is time-tested, and model lines are wide enough and allow you to find tires for every taste and for any car.

We hope that, based on the above tips, you can easily choose suitable tires that will allow you to get the maximum pleasure from driving.
