Each tire has a tread pattern and is by no means an aesthetic element. The system of notches applied to the tire provides maximum grip of its surface with the road. Thanks to them, water is removed from under the wheels of the car, cleaning from snow and dirt. Therefore, it is so important to monitor the height of the tread pattern.

For new tire it will be from 7.5 to 8.5 millimeters. This height is standard for summer tires general purpose, suitable for driving passenger car on asphalt. So, for an SUV, this number can reach 17 mm.

In some cases, it is possible to purposefully reduce this indicator for a passenger car. We are talking about sports cars that drive almost constantly in speed mode. In this case, the tread depth is 5-6 mm.

Minimum depth

ATTENTION! Found a completely simple way to reduce fuel consumption! Don't believe? An auto mechanic with 15 years of experience also did not believe until he tried it. And now he saves 35,000 rubles a year on gasoline!

During operation, the tire wears out and gradually wears out. Under the new rules, a vehicle is approved for use if the tread depth of summer tires is at least 1.6 mm. This height is the maximum allowable - then it is already necessary to change the tires to new ones.

Moreover, experts recommend replacing tires already when the residual height reaches 2 mm. This is logical: in this case, it’s not worth the risk, since an almost “bare” tire does not provide proper grip for the car on the road, which can lead to an emergency.

In addition, after this law came into force, traffic police officers can stop and inspect a car, specifically tires. Failure to comply with the proper tread height can result in a fine.

What affects wear?

According to expert estimates, on average, each tire "lives" about 10 years. Given the state of roads in the Russian Federation, as well as the desire of many to drive aggressively, this period can be reduced to 5-6 years. The main factors include:

• travel time on the road;
• appropriate adjustment of toe and camber;
• changing pressure inside the wheel;
• terms of use of the car.

Often to rapid wear caused by the use of the wrong type of rubber. Most of the factors can be avoided if you properly monitor the condition of the car and the tires themselves.

Tire wear assessment

This kind of procedure is carried out for the most part in two cases:

• checking tires for suitability and the need for replacement;
• checking before buying / selling used tires.

And if in the first case everything is clear, in the second one you should be extremely careful: a tire with already 50% wear, although it is subject to operation, will not last as long as we would like. It is difficult to determine this with the naked eye, so you have to measure it.

What are the ways?

There are a number of methods to determine what is the residual depth of the tire:

Additional points

It is important that such measurements must be carried out along the entire tire and in its different sections, since it is often erased unevenly. If this is noted, it is worth, among other things, to check the location of the wheels and adjust their angle.

When checking a tire, you should carefully monitor the presence or absence of mechanical damage: cuts, cracks, chips and non-through holes both on the tread itself and on the sides. Any, even the smallest crack, can cause a car wheel to break while driving, which is extremely unsafe. If it is not possible to eliminate them, the tire must be replaced with a new one.

If complete replacement tires for some reason is not feasible, the installation of new tires is carried out on the drive wheels. It is not recommended to change the tire on only one wheel - this will reduce the car's handling. To avoid this, tires are changed on one of the axles.

Good afternoon, dear reader.

This article will talk about updating the requirements for the tread pattern of car tires.

Changes in regulatory documents will only take effect on January 1, 2015, but I recommend that you study them in advance.

So, today the following documents will be considered: "List of malfunctions and conditions under which the operation of vehicles is prohibited" (document text) and "Technical regulations on the safety of wheeled vehicles" (text).

Let's get started.

Fault List Changes

Let's start with the changes made to the list of malfunctions in which the operation of vehicles is prohibited:

5.1. Tires cars have a residual tread height of less than 1.6 mm, trucks - 1 mm, buses - 2 mm, motorcycles and mopeds - 0.8 mm.

Note. For trailers, the norms of the residual height of the tire tread pattern are established, similar to the norms for tires of vehicles - tractors.

5.1. The remaining depth of the tire tread pattern (in the absence of wear indicators) is no more than:

for vehicles of categories N2, N3, O3, O4 - 1 mm;

Note. The designation of the vehicle category in this paragraph is established in accordance with Appendix No. 1 to the technical regulation of the Customs Union "On the safety of wheeled vehicles", adopted by the decision of the Commission of the Customs Union of December 9, 2011 No. 877.

First of all, they are striking, which were not previously mentioned in the rules of the road.

The changes affected trucks with license maximum weight up to 3.5 tons, i.e. category B trucks. Previously, rubber could be used on such vehicles until 1 mm of tread remained. From January 1, 2015, the requirements will be slightly more stringent - 1.6 mm. For example, these requirements will affect small trucks (Gazelle, Mitsubishi L200, Volkswagen Amarok, etc.).

In addition, they introduce Additional requirements for winter tires labeled "M+S", "M&S", "M S". Such tires must have a residual tread depth of at least 4 mm. Moreover, this value does not depend on which category of vehicle the tires are installed on.

Technical regulation changes

Similar changes also affected Annex 7 to the technical regulation on the safety of wheeled vehicles:

5.2. The requirements of paragraphs 2.3.2 - 2.3.4 of Appendix No. 5 to this technical regulation apply.

5.2. The tire is considered unusable

5.2.1. When one wear indicator appears (a protrusion along the bottom of the treadmill groove, designed to visually determine the degree of wear, the depth of which corresponds to the minimum allowable tire tread depth).

5.2.2. With a residual depth of the tire tread pattern (in the absence of wear indicators) no more than:

• for vehicles of categories L - 0.8 mm;
• for vehicles of categories N2, N3, O3, O4 - 1 mm;
• for vehicles of categories M1, N1, O1, O2 - 1.6 mm;
• for vehicles of categories M2, M3 - 2 mm.

5.2.3. With residual tread depth winter tires designed for operation on icy or snowy road surfaces, marked with a sign in the form of a mountain peak with three peaks and a snowflake inside it (see Figure 5.1), as well as marked with signs "M + S", "M & S", "M S", during operation on the specified coating - no more than 4 mm.

Figure 5.1. Winter tire marking

5.2.4. In the presence of local tire damage (punctures, through, blind and other cuts), which expose the cord, as well as delaminations in the carcass, breaker, bead (bloating), local delamination of the tread, sidewall and sealing layer.

For an objective comparison of the old and new version of the regulations, I will cite paragraphs 2.3.2 - 2.3.4 of Appendix 5, to which a link is given:

2.3.2. Tire tread height must be at least:

2.3.2.1. For vehicles of categories L - 0.8 mm;

2.3.2.2. For vehicles of category M1 - 1.6 mm;

2.3.2.3. For vehicles of categories N and O - 1.0 mm;

2.3.2.4. For vehicles of categories M2 and M3 - 2.0 mm;

2.3.2.5. For trailers (semi-trailers) - the same as for the tractors with which they work.

2.3.2.6. For winter tires, as well as tires marked with the sign "M + S" - 4.0 mm.

2.3.3. A tire is considered unusable when:

2.3.3.1. The presence of a section of the treadmill on which the height of the tread pattern along the entire length is less than that specified in paragraph 2.3.2. The size of the section is limited by a rectangle, the width of which is not more than half the width of the tread tread, and the length is equal to 1/6 of the circumference of the tire (corresponding to the length of the arc, the chord of which is equal to the radius of the tire), if the section is located in the middle of the tread tread. At uneven wear tires, several sections with different wear are taken into account, the total area of ​​\u200b\u200bwhich has the same value;

2.3.3.2. The appearance of one wear indicator (a protrusion along the bottom of the groove of the treadmill, the height of which corresponds to the minimum allowable height of the tire tread pattern) with uniform wear or two indicators in each of the two sections with uneven wear of the treadmill;

2.3.3.3. Replacement of spools with plugs, plugs and other devices;

2.3.3.4. Local damage to tires (breakdowns, swelling, through and non-through cuts), which expose the cord, as well as local delamination of the tread.

2.3.4. Not allowed:

2.3.4.1. The absence of at least one bolt or nut for fastening discs and wheel rims;

2.3.4.2. The presence of cracks on the disks and wheel rims, traces of their elimination by welding;

2.3.4.3. Visible violations of the shape and size of the mounting holes in the wheel disks;

Just like in the list of malfunctions discussed at the beginning of the article, the technical regulations tighten the requirements for category B trucks. Starting from January 1, 2015, they must have a residual tread depth of more than 1.6 mm.

In addition, the technical regulations provide for the marking of winter tires (a mountain peak with three peaks and a snowflake). If your tires have a similar emblem, then it is forbidden to operate them with a residual tread depth of less than 4 mm.

Well, one more thing. Previously, the requirements of paragraph 2.3.4 were imposed on the wheels of vehicles in operation. For example, the absence of wheel bolts, the presence of cracks in disks and rims, the violation of the shape and size of mounting holes, etc. were not allowed. No matter how strange it may sound, but from January 1, 2015, technical regulations will not impose such requirements on cars.

Good luck on the roads!

This is what happens? Clause 2.3.4.4. One axle vehicle tire different sizes, designs (radial, diagonal, chamber, tubeless), models with different tread patterns, frost-resistant and non-frost-resistant, new and restored, new and with a deep tread pattern. Does it also stop working?

This is deleted from the Technical Regulations, but remains in the annex to the traffic rules (clause 5.5 of the List of malfunctions)

The changes affected trucks with a maximum permitted weight of up to 3.5 tons, i.e. category B trucks. Previously, rubber could be used on such vehicles until 1 mm of tread remained. From January 1, 2013, the requirements will be slightly more stringent - 1.6 mm. For example, these requirements will affect small trucks (Gazelle, Mitsubishi L200, Volkswagen Amarok, etc.).

Error in the text: From January 1, 2013 .... Still, I think it means "From January 1, 2015"

GrammarNazi, Thank you! Changes have been made to the article.

If you notice something like this, be sure to write.

Good luck on the roads!

Summer tires can be used winter period if the road surface is not icy or snowy? In Crimea, in winter, the temperature is mostly above zero and without snow.

Can. Though in the Crimea, even in Vorkuta. The main thing is to complete the item:

5.5. Tires of various sizes, designs (radial, diagonal, chamber, tubeless), models, with different tread patterns, frost-resistant and non-frost-resistant, new and retreaded, new and with a deep tread pattern, are installed on one axle of the vehicle. The vehicle has studded and non-studded tires.

Comments

How to understand (no more)?

5.2.3. With a residual depth of the tread pattern of winter tires intended for use on icy or snowy road surfaces, marked with a sign in the form of a mountain peak with three peaks and a snowflake inside it (see Figure 5.1), as well as marked with the signs "M+S", "M&S ", "M S", during operation on the specified coating - no more than 4 mm .....

It turns out that with a tread depth of 3mm, operation is possible?

5.2. The tire is considered unusable:

In the table in decoding: "L - mopeds, motorcycles, ATVs, etc.", the error is not

ATVs, and ATVs!!! So?????

5.2. The tire is considered unusable:

With a residual tread depth of winter tires ... - ... no more than 4 mm.

Is 3mm bigger than 4mm? No more, equals less!

"No more" is "less than or equal to", not just "less than". From the point of view of mathematics. Although in reality the boundaries and their belonging cannot be precisely established.

lego, thanks for the information. You are right, the article will be corrected.

Good luck on the roads!

Hello.

2.3.4.4. Installation on one axle of a vehicle of tires of different sizes, designs (radial, diagonal, chamber, tubeless), models with different tread patterns, frost-resistant and non-frost-resistant, new and retreaded, new and with deep tread pattern.

Vyacheslav, Hello.

There are no spares exceptions. If they stop, they will fine you. Therefore, if your spare tire is different from the rest of the wheels, then use it as little as possible (immediately head to the nearest tire shop).

Good luck on the roads!

Hello.

2.3.4.4. Installation on one axle of a vehicle of tires of different sizes, designs (radial, diagonal, chamber, tubeless), models with different tread patterns, frost-resistant and non-frost-resistant, new and retreaded, new and with deep tread pattern.

And about the spare wheel, is there an exception anywhere?

5.5. Tires of various sizes, designs (radial, diagonal, chamber, tubeless), models, with different tread patterns, frost-resistant and non-frost-resistant, new and retreaded, new and with a deep tread pattern, are installed on one axle of the vehicle. The vehicle is equipped with studded and non-studded tires.

Within one day they will not be fined.

Many imported cars have a "dock", which is similar to a bicycle wheel. And the "stowaway" and any "reserve" can be used to follow to the place of repair. According to the annex to the SDA "LIST OF FAULTS AND CONDITIONS UNDER WHICH OPERATION OF VEHICLES IS PROHIBITED" the operation of the vehicle is prohibited. And even after stopping the IDPS on this issue, you have a day to fix this problem.

Government Russian Federation decides:

1. Approve the attached changes that are made to the acts of the Government of the Russian Federation.

5.2.3. With a residual tread depth of winter tires intended for use on icy or snowy road surfaces, marked with a sign in the form of a mountain peak with three peaks and a snowflake inside it (see Figure 5.1), as well as marked with signs "M S", "M HE MORE THAN 4 mm

and in court I can appeal if they fine me that I have 3 mm, but the law clearly states no more than 4 ??

Dmitry, you took the phrase out of context. You can't do that in court.

This List establishes malfunctions of cars, buses, road trains, trailers, motorcycles, mopeds, tractors, other self-propelled machines and conditions, under which their use is prohibited..

It is prohibited to operate trucks of category N2 and N3 if the residual depth of the tire tread pattern (in the absence of wear indicators) is not more than:

The residual height of the bus tire tread pattern must not be less than 2 mm.

When are you allowed to drive a car?

Of all the above cases, only installation on rear axle retreaded tires are not a reason to prohibit the operation of your vehicle.

Every car owner knows that the wheel is one of the most important parts of the car. A vehicle wheel is a disc and a tire. Due to the force of friction, traction with the road surface and the movement of the car occur. The first tires were created in order to reduce the effort required to move loads. Today they are responsible for vehicle handling and safety on the road. The characteristics of tires depend on the chemical composition and tread pattern.

1 Types of drawings - why they are different

Rubber is the main ingredient in a tire. Carbon black, silicic acid, sulfur and other components are added to it to give tires the desired characteristics. The goal of manufacturers is to achieve maximum resistance to external influences, such as friction and elevated temperature.

For different operating conditions, tire manufacturers develop a special tread. Depending on the purpose, tires are divided into:

• road - designed for driving on a hard road surface;
• mud - for extreme conditions (soil, mud);
• universal - used for all types of road surface.

Numerous grooves and longitudinal grooves in the tread summer tires designed to carry water. The behavior of the car on the road depends on the type of pattern. The asymmetry and directionality of the tread give better handling, but due to the complexity of production, such tires are more expensive. In addition, they are noisier.

2 Tread depth - what should it be

Over time, the tire wears out and the properties laid down by the manufacturer are lost. And the smaller the tread depth becomes, the stronger the changes for the worse are felt.

There is such a thing as critical tire wear, when it cannot provide normal grip on the road and its use becomes unsafe. The minimum tread height of summer tires is prescribed in the rules of the road. For car tiresit is 1.6 mm, and for buses - 2 mm. With a smaller balance, the operation of the vehicle is prohibited. Let's see why.

When the tread depth becomes smaller, the tire begins to drain water worse. As a result, hydroplaning occurs - partial or even complete loss of traction and, as a result, control. Since tire contact with the road surface decreases as tire wear increases, it is more difficult for a vehicle to brake even on dry surfaces. All troubles become even more noticeable when high speed ride.

To keep your rides safe, the condition of your tires needs to be checked periodically. The remaining tread depth can be determined in three ways:

1. A caliper is the most accurate way to measure. To do this, you need to pull out the depth gauge of the device, lower it to the lowest point and lower the bar until it stops at the top point of the tread. According to the indications on the scale, the remaining rubber is determined.
2. Coin and ruler. To perform the measurement, insert a coin into the recess and mark the height of the tread with a marker. Now with the help of a ruler you can find out the condition of the rubber.
3. PO indicators. Almost all manufacturers apply various marks that allow you to control the degree of tire wear.

With the first and second control methods, measurements are taken in several places, since wear is uneven.

As for labels, there are several types of them:

• voluminous;
• digital;
• drawings.

Volumetric marks are usually ribs, the height of which will serve as a signal that the tires should be changed.

Digital marks are applied in the form of numbers - from 2 to the value of the tread height of the new tire.

Summer tires sometimes have drop patterns, the disappearance of which signals the danger of aquaplaning.

3 Causes of premature wear

The tire wear rate is affected not only by its chemical composition, but also by some other factors. Tire wear can be caused by:

1. The pressure is above or below the set value. Under normal tire pressure, the tread surface is fully in contact with the road surface. When the pressure is lower than needed, the rubber wears out at the edges. If the wheels are pumped - erasing occurs in the middle of the tread.
2. Incorrect wheel alignment. In this case, the rubber is "eaten" along the outer or inner edge of the wheel, depending on which way it is tilted.

In both cases, the load is not distributed evenly, but on certain sections of the wheel. Because of this, the rubber wears down to zero in one place, while wear remains acceptable in another.

4 Shelf life of wheels

Besides allowable wear tires, the natural aging of rubber should be taken into account. Over time, it loses elasticity, becomes hard. Sometimes cracks appear on the surface of the tire, due to which air can leak in the future. There are even cases when the tire explodes.

No manufacturer gives information about how many years a tire can be used. But each tire has a label indicating the year and week of manufacture. You need to remember this point when buying new rubber. It's not worth the risk, it's better to opt for fresh tires.

When buying used wheels, you should pay attention to the following points:

• degree of wear;
• wear uniformity;
• year of issue;
• visual condition (cracks, delaminations).

In addition to the described methods for determining the need to replace old tires with new ones, you should also rely on your own feelings. If the car has become worse to slow down, the grip is insufficient, or control is lost on a wet road, then you should not hesitate to replace tires.
