Validity of winter tires. Winter tire life: how to extend the life of winter tires

26.06.2020

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:

European manufacturers. The mileage, taking into account different models, is in the range of 50-60 thousand km.
Russian manufacturers. Many models are licensed, or our own developments, the quality of which has improved. Mileage is from 40 thousand km and above.
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 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.

terms of Use

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

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.
Tire pressure. Initially, in winter, increase the indicator by 0.2 bar in relation to the one set by the car manufacturer. 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!
Driving under load. With a constant full load of the car, even the best winter tires will reduce their resource by 20-30%.
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, you should strictly observe the Rules of the Road, changing tires in a timely manner.

Driving style and road conditions

Long-term tests of the use of winter tires have shown that for winter road conditions, driving at a speed of 120 km / h leads to complete wear 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 disable the winter wheel 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.

A car tire is a rubber elastic shell that is mounted on a disc rim. It is she who is in direct contact with the surface of the roadway and is directly designed to reduce small fluctuations on the roads, as well as to compensate for flaws in the trajectory of the wheels. During operation, it is subjected to heavy loads of a diverse nature, therefore it naturally has its own service life, which is influenced by a number of factors.

Expiration date of tires according to GOST

Best before date– the period during which the company guarantees the possibility of using the product for its intended purpose and bears full responsibility for defects that arose through its fault.

When buying tires, you need to look so that no more than three years have passed from the moment of production. The date of manufacture and any other information is very easy to find out, it is listed on among the general information about dimensions, design, speed and load ratings.

Tire production date

Russian legislation establishes the service life of car tires under warranty according to GOST 4754-97 And GOST 5513- 5 years from the date of manufacture, but for tires, first of all, the main indicator is the quality of the product, and not the time of its use.

According to GOST, the average shelf life of tires must be calculated in this order:

ZR. This is how high-speed options are designated, these products can be used at speeds over 240 kilometers per hour. The product must fully retain its properties for 6 years.
H - used at a maximum speed of 210 kilometers per hour, serve up to 5 years.
S - maximum speed - 180 kilometers per hour. Can be used up to 4-5 years.

Experts recommend replacing tires before they reach their expiration date. Some motorists believe that if rubber is rarely used, while its age is already 5-6 years old, but this is an erroneous opinion! Indeed, due to the fact that defects appear in tires during operation and storage, they are associated with its oxidation and cracking - at a critical moment, it can let you down.

Tire shelf life

Shelf life- a certain period during which the goods, subject to the established rules of storage and operation, must retain all their properties. If the shelf life has expired, this does not mean at all that the product is unsuitable for use, but its technical characteristics may decrease.

Tires can age through physical and chemical processes, this hypothesis applies to tires that are not used or little used. To prevent the aging process itself, special substances are added to the rubber compound that help counteract harmful chemical compounds with oxygen and ozone. Doing so will ensure that, when stored properly, the tire will meet the definition of a new tyre.

It should be noted that the warranty the shelf life is not the service life. The storage period for five years is set, not because the tire will deteriorate after that, but because, according to the law, the manufacturer does not have the right to establish a shorter warranty period, which is protection for the end user.

In recent years, many American experts believe that the shelf life and operation of car tires should be limited to 10 years. In turn, German experts believe that the expiration date of tires should be limited to 6 years, this also applies to new tires.

Rules and regulations for the storage of pneumatic tires in accordance with GOST 24779-81:

Packaging, transportation and specially equipped storage areas must prevent oxygen, light, heat, ozone, organic solvents, mineral oils, lubricants, fuels, acids and alkalis from attacking tires.
Busbars should not come into contact with copper or corrosive substances, nor should they be loaded, kinked, or supported with sharp, uneven surfaces.
If you store tires in a dark, dry and cool room, then their aging will be significantly slowed down, and vice versa, if the room is humid and there are temperature fluctuations, then the aging process is accelerated.
Tires that are intended for repair and retreading should be well washed and dried.
Tires should be stored at a temperature not higher than 35 °C and not lower than 25 °C. Avoid direct contact with a heat source, do not leave in direct sunlight at a humidity of less than 80%.
If tires are stored outdoors, they should be covered with an opaque waterproof cover and raised off the ground to ensure adequate ventilation to prevent the formation of a steam bath.
It is strictly forbidden to store tires on a wet, greasy/oily surface contaminated with gasoline or oil products.
So it is not advisable to keep them near heat sources or near open flames.
Do not store tires on reflective surfaces (such as snow, sand) or heat-absorbing surfaces (such as black asphalt).
It is not recommended to store tires near an electric motor or with other sources of ozone. The level should not exceed 0.08 ppm.
Do not store tires near chemicals, solvents, fuels, carbohydrate oils, paints, acids, disinfectants.
Do not use the rail as a work surface or tool rack. Do not put a burning cigarette on tires.

Well-known brands of imported tires, such as: Bridgestone, Michelin, Goodyear and Dunlop serve up to 10 years or more from the date of manufacture, this period is considered generally accepted throughout the world. But the general expiration date and storage in the warehouse, from the date of issue, tires Continental is not more than 5 years.

Although, as we have already figured out, the storage conditions of tires mean a lot, not only new ones, but also those that were removed from the car until the next season. For example, nokian tire expiration date ranges from 3-5 years, subject to verification at least 1 time per year, after 5 years of use.

Unfortunately, the legislation does not establish the permissible shelf life of tires in a warehouse, but experts believe that a tire that has lain there for about 5 years is still equal to a new one.

Tire life and operation

Lifespan of car tires- this is the period during which the manufacturer gives a guarantee for the tires and is fully responsible for any defects that will be detected during their operation. According to manufacturers, tires should last at least ten years, although in practice they have to be replaced approximately every 5-6 years, in some cases even less.

Factors that affect tire life

There are many different factors that affect tire wear, the main ones are listed below:

From the vehicle and its carrying capacity: what is the maximum load the car can carry and whether your tires can withstand it (shows). Please note that depending on this parameter, there are certain norms for the mileage of car tires on the roadway:
- For passenger cars: carrying capacity up to 2 tons, mileage 45 thousand kilometers.
- For trucks: carrying capacity from 2 to 4 tons, 60 thousand kilometers.
- Trucks with a carrying capacity of over 4 tons - from 65 to 70 thousand kilometers.
Depending on tire size. Tires with a low profile most often tap on the disc on the stones, and therefore serve less. If the tires are wide, then the friction increases when cornering, especially in winter.
Driver's driving style. The tire wears out quickly if the motorist often uses a sharp brake or, on the contrary, accelerates quickly.
Road condition that you drive every day.
From distance, which you pass and frequency of use.
Tire quality plays a very important role, for example, rubber made in China is short-lived, while rubber from well-known brands will last much longer. It is known that the service life of Chinese rubber is about two seasons, and branded rubber can last about seven years. When choosing tires, you need to pay attention to the manufacturer, because fakes are often sold under well-known brands.
Various mechanical damage, such as cuts, bumps after impacts, deformation after emergency braking, accidents, etc.

Next, we will consider in more detail the instructions for certain actions that need to be performed in case of wear on car tires.

How to understand that the service life of car tires is over

When diagnosing tires, in addition to the fact that it is imperative to pay attention to, there are also other equally important factors indicating the end of the service life.

In order to determine when the life of car tires ends during a detailed inspection, you need to pay attention to the following points:

If you notice that tire tread worn down to the level of the jumpers between the tread, it means that the tire has reached the end of its useful life. The degree of wear can be determined by eye or with the help of tools. On the outside, the tire surface has numbers with different depths, so you can easily determine the degree of wear. In order to measure the tread height, you can use a ruler with a special depth gauge. For summer tires, this parameter should be equal to more than 1.6 mm, in turn, for winter tires - more than 4 mm. If these parameters are less, then it is necessary to replace the tires. When the wear is uneven, then measurements should be taken in the area where the wear is most visible. Otherwise, if the tread edge is worn on only one side, then it means that it was broken.
Small cracks on the side on tires indicate the aging of rubber and warn of replacement, while deep cuts require immediate replacement.
If there is swelling on the side of the tires - "hernia", then this means that the threads of the cord layer have broken, in this case the tires must also be changed immediately. Also, such “hernias” can appear on the inside of the wheel, so you need to be extremely careful and inspect in time.
If tire wear on the outside it is much larger than in the central part, then this may mean that the tires did not have enough pressure, if everything is vice versa, they are more worn out in the center, and less along the outer edges, then there was an excess of pressure.

When any defects were noticed in the tires, it is recommended to carry out a replacement, and not a rescue restoration, in order to somehow extend the period of use.

To prolong the life of your tires, you need to periodically check them.

How to extend the life of tires

In order for your tires to be more durable, you need to follow certain rules of use:

If there are no obvious air leaks, you need to check the tire pressure every 2-3 weeks of operation. This is because uneven tire pressure results in uneven tread wear. If by 10%, then this can lead to a 10-15% reduction in tire life. If the pressure is increased, then the wear also increases, but 2 times less than in the reduced one.

Since there is always more wear on the front (driving) wheels, then every 10-15 times. thousand or at the time of changing seasonal tires, it is advisable to change it in places.

Changing front tires to rear

Scheme of permutation of 5 car wheels

Please note that although there are tires with directional and non-directional patterns, you still cannot change the direction of rotation of the wheel. And in the second option, the front wheels must be reboarded before being installed back.

It is necessary to check whether the tires are correctly installed in relation to the rims, which is usually indicated on the sidewalls of the tires, this is important, since when the tires rotate in the opposite direction to the design, all their performance will be significantly reduced in all modes of operation of the car.

Non-directional tire replacement scheme

Shift scheme for all-wheel drive cars

If you bought new studded tires, then first, they need to be run in the first 500 km while avoiding sharp turns, braking and acceleration, then the tires will last much longer and will have the correct fit.
It is best to buy and install tires on all wheels from the same manufacturer and with the same pattern.
Follow all rules for storing removed tires.
It is important to regularly wash off the dirt from the tires with special care products, while paying attention to the fact that after washing off the products they do not remain in the tread grooves.
To maintain their appearance, you need to use special care products: tire conditioner, conditioner cleaner, tire color restorer.
It is necessary to avoid close access to the curb or other ledges so as not to damage the thin side of the tire.
If you are going on a long trip, it is better to increase the inflation pressure in the tires, this will save fuel and reduce heat generation.
Try to maintain a moderate driving style.
No need to load the car, at 20% overload, the service life is reduced by 30%.
Avoid sharp obstacles, because tire fractures can contribute to the destruction of the cord layer under the tread.
Check the wheel alignment once a year. Also, this operation must be performed after repairing the steering gear, replacing the hinges, as well as after strong impacts that can deform the elements in the chassis.
Follow the wheel balancing, it should be carried out after about 10,000-15,000 km or after each repair with tire removal.

Experts recommend regularly checking the condition of your tires and the degree of tread wear. After all, it is much more profitable to fix a malfunction in the early stages than to change all the rubber later. It must be remembered that proper and timely tire care is your safety and guarantee of the durability of your rubber.

They have a limited service life. At the same time, a number of factors affect the shelf life of rubber, ranging from natural wear during operation to aging of rubber, change and gradual loss of the declared properties.

As practice shows, the service life of winter tires is less than summer tires. Moreover, the shelf life of winter studded tires in some cases differs from analogues without studding. Next, we will consider what is the service life and shelf life of winter tires.

Winter studded tires: service life

Once again, we note that the life of winter tires is somewhat less than the same period for summer tires. Although visually the tires are almost the same, the composition of winter and summer tires is very different. Without going into too much detail, a summer tire is stiff, while a winter tire is softer and more elastic, causing it to wear harder and wear faster.

Please note that in case of violation of the storage and operation rules, the aging process of rubber and the general wear of winter tires can be significantly accelerated. For this reason, when choosing winter tires, you need to pay special attention to a number of features.

First of all, if new or used tires are purchased, it is necessary to determine the manufacturer and know the date of manufacture of the tire in order to understand how much more such tires are produced. In the case of buying winter studded tires, these aspects need to be given increased attention.

Please note, in order to determine how much winter tires run, it is worth dividing tires into expensive branded and cheap ones. Branded products of well-known world manufacturers are distinguished by wear resistance. If the tire is stored correctly, correctly selected for a specific car, installed on a disk, taking into account the characteristics of the tire, then the service life of winter studded tires or Velcro can be 5 years or more.

However, cheap tires (Chinese or budget domestic) under the same conditions may not come out even for a couple of seasons. The fact is that expensive tires contain patented components that allow rubber not to age and retain its properties for a long time. Cheap tires usually do not have such additives or their amount is negligible, which leads to cracking of the tire, loss of elasticity, etc.

Service life of winter tires

Back to studded winter tires. Often, manufacturers determine that or about 50-60 thousand km. The same applies to Velcro. However, in reality, such an indicator can be achieved if the “fresh” tire by the date of manufacture is operated under almost ideal conditions.

Such conditions for winter tires should be understood as a stable near-zero temperature, constant maintenance of the recommended tire pressure, as well as driving at low speed on roads that are covered with a layer of snow and ice. In other words, you need conditions for which a studded tire or Velcro is designed.

If the car is operated aggressively (sharp starts, active braking), the car often drives at high speed on dry asphalt, winter tires are operated at positive temperatures (above +8 degrees Celsius), in this case the spikes themselves fly out and the tire wears quickly.

In addition to the service life of rubber, you also need to pay attention to expiration dates. These are slightly different concepts that need to be distinguished. Simply put, the service life is actually the resource of the tire in use and depends on many factors, while the shelf life depends on the date of production and storage conditions.

To be clear, even if the tire is not in use, but simply stored new in a warehouse, rubber will still age and eventually become unusable. As a rule, if the tires have been in storage for several years (4-7 years or more), you should not expect full compliance with all the declared performance characteristics.

It turns out that they are completely new in terms of wear, but old tires according to the date of manufacture will wear out stronger and faster when driving after installation on a car, they can be noisier, lose elasticity.

Microcracks appear on the surface, which subsequently increase rapidly under loads. It is for this reason that tires that have been in stock for a long time are usually sold at significant discounts. It is also important in what conditions the rubber was stored. High humidity, elevated temperatures, direct sunlight are not allowed. Also, winter tires are stored in special bags to minimize contact with air.

Otherwise, winter tires, which contain many more components to maintain elasticity, quickly dry out and crack. This means that if the storage conditions are fully met, the tire will retain its properties even after 2-3 years, while a gross violation of the conditions may mean that after a couple of years the tire is not suitable for use.

To find out the date of manufacture of tires, you need to pay attention to the marking. The date of manufacture is applied on the side surface, in the form of a four-digit number (after 2000). However, it must be remembered that until 2000 the designations were somewhat different. On this topic.

What is the life of the tires: winter tires

So, if we summarize the information received, the service life of winter studded tires or Velcro can be determined taking into account the features discussed above.

First, pay attention to the date of manufacture and storage conditions of winter tires;
Second, we determine the manufacturer of the tire (branded or cheap tire);
Third, we estimate the conditions under which the car will be operated (snow, asphalt, etc.)
Fourth, we take into account the type of tire itself (studded or studless).

If we talk about how long the life of winter studded tires is, in this case the most important indicators will be the age of the rubber, operating conditions and mileage.

As a rule, such tires of well-known brands (taking into account that no more than 3 years have passed from the date of issue of the tires, the rubber was stored correctly and was installed on the disk, taking into account all the requirements), they nurse about 50 thousand kilometers on snow and ice.

However, studded wheels can last no more than 30 thousand km. when driving on asphalt, especially if the car is operated aggressively. As a general rule, more than 60% missing studs and more than 50% tread wear indicates the need for tire replacement. In extreme cases, you can re-stud the rubber.

At the same time, it is important to understand that even if the conditions are optimal, the tires are in excellent condition, the mileage on them is minimal, such tires will still lose their properties after 8-10 years.

Visually, the aging of rubber is indicated by a change in color (from black to gray), the appearance of cracks, delamination, etc. In this case, tires need to be changed regardless of the condition of the tread, studs, sidewalls, etc.

As practice shows, on average, good quality winter tires last about 50 thousand km or 5 years. It turns out that the service life of rubber is about 5 years with relatively small runs up to 10 thousand km. for the season.

By the way, the terms of operation of winter tires are separately indicated in the traffic rules. According to the traffic rules, rubber must be changed taking into account wear, that is, when the tread depth is less than the 4 mm mark. Winter tires must be marked (snowflake icon, M+S, etc.).

Please note that there are several ways to increase the life of winter tires. First of all, you must follow the rules for the operation of tires. It is also important to constantly maintain the recommended tire pressure by checking the indicator with a pressure gauge. If the pressure is higher or lower than normal, tire wear is significantly accelerated.

The condition of the chassis of the car, more precisely, the suspension, also greatly affects the wear of rubber. It is required to regularly check the wheel alignment, as well as eliminate the existing malfunctions.

Finally, we note that rapid wear of rubber, especially soft winter tires, occurs when an imbalance of the wheels appears, a beating is felt on the steering wheel. In this case, the problems may be with the disc itself or the tire (it is necessary to roll the disc and balance the tire).

Also, imbalance in winter often occurs as a result of the accumulation of snow and ice on the disc, which also leads to wear. To eliminate this factor, it is recommended to warm the car in a warm parking lot or garage, remove snow and ice from the wheels at a car wash, etc.

As a result, we note that winter tires are soft, afraid of side cuts and heavy loads on the sidewall. This means that when cornering, it is better to slow down as much as possible, avoid getting into pits and potholes (especially with sharp edges). This approach avoids the premature appearance of hernias on the tire, cuts, tears and other defects.

1. Tire life - signs of its end.

The service life of automobile tires is the period during which the manufacturer guarantees the possibility of using tires for their intended purpose and is fully responsible for any inconsistencies in performance and emerging product defects. Car tires, according to manufacturers, last up to ten years. But in practice, they have to be changed approximately every 5-6 years, and sometimes even more often, which depends on many factors.

When assessing the life of tires, it is also necessary to take into account the mileage of the car (since each motorist drives differently, some 10 km a day, and some all 100). According to the accepted rules, the mileage standards for car tires are:

1. For passenger cars(carrying capacity up to two tons) - 45 thousand kilometers.

2. For trucks(carrying capacity from two to four tons) - 60 thousand kilometers.

3. For trucks(carrying capacity from four tons) - from 65 to 70 thousand kilometers.

Good tires are the key to a safe ride. But even the best rubber eventually wears out and loses integrity. Therefore, the driver should always monitor the degree of tire wear. You need to keep track of both summer and winter tires. Sometimes the service life of tires may not even reach five years, which, as already noted, is due to many factors that we will consider further.

How to determine in advance the approaching end of the life of car tires?

1. If the tire tread is worn down to the level of the jumpers between the tread, then the tires have served their purpose. You can determine the degree of wear by eye or with the help of tools. To measure the tread height, use a ruler with a special depth gauge. For summer tires, this parameter should be more than 1.6 mm, and for winter tires - more than 4 mm. If these parameters are less, you should think about replacing tires. In case of uneven wear over the entire surface, measurements should be taken at the most worn area.

2. On the surface of some tires there are numbers of different depths. And you can judge the degree of wear by how many numbers are visible at the moment.

3. If the car has studded tires, then the need to replace it can be judged by how many studs are left on it (if less than half is left, it should be replaced).

4. Small cracks on the sidewalls of a tire indicate the aging of rubber and are harbingers of its imminent replacement. But deep on the sidewalls - an alarm signal for an immediate replacement of rubber.

5. Swollen sidewalls (the so-called “hernias”) appear due to a rupture of the cord layer and indicate the need to replace tires (sometimes “hernias” occur from the inside, so you should always be very careful about their inspection).

If you find something similar, then it's time to think about replacing tires. And to confirm your fears, the right thing to do would be to contact a specialist master who accurately diagnoses the condition of the tires.

2. We estimate the life of car tires - should we trust the manufacturer?

Car tires come in different types, depending on the season for which they are intended:

1. Summer.

2. Winter.

3. All season.

Tires are made from different rubber for different seasons. Summer tires are made of harder rubber than winter or all-season tires. Therefore, their service life will also be longer. As for all-season tires, they are not recommended for use in regions where the temperature during the winter season is much below zero, as they will not live up to your expectations and will not last very long.

According to manufacturers, the service life of car tires ranges from seven (for winter) to ten (for summer) years. But one should not blindly believe such statements. The fact is that many factors affect the life of car tires, including:

1. The nature of the driver's driving (for example, extreme driving enthusiasts wear tires much faster than those who drive carefully).

2. The quality of the road surface, which in our country is far from ideal.

3. The quality of automobile rubber greatly affects the life of tires. Cheap Chinese rubber will last much less than rubber from well-known brands.(The service life of Chinese rubber is about two seasons, and branded rubber is about seven). But a famous brand is not a guarantee of success. Indeed, very often fakes are sold under the label of well-known brands, and they, a priori, cannot last for a very long time (during the purchase, be sure to remember this aspect and choose wisely).

4. Various mechanical damage (for example, cuts, bumps after impacts, deformations as a result, accidents, etc.).

How to determine the causes of tire wear? There are many reasons for tire wear. And this is not only the gradual erasing of the tread when moving on the road (in accordance with the mileage for which they are designed). It is not difficult to determine the causes of wear (this is done by the surface of the tire and the tread pattern). Let's consider several options.

1. If the outer edges of the tire are worn an order of magnitude more than the central part, then there was insufficient pressure in the tires. And if, on the contrary, the central part is more worn than the outer edges, then the pressure was excessive.

2. If the tread edges are worn on only one side, then the camber-toe angles have been violated.

3. Uneven tire deformations indicate a driver's addiction to extreme driving with sudden braking.

Summing up, it is worth noting that manufacturers, indicating the life of their tires, are guided by ideal conditions. And each motorist must independently predict these terms for himself, paying attention to the considered aspects.

3. The service life of car tires - can it be increased?

The service life of tires is determined by the mode of their use, storage conditions and other factors. But it is impossible to accurately calculate this value, since there are a lot of variables in this equation. In order for car tires to last as long as possible, it is necessary to take care of them regularly and make sure that they are not damaged.

1. It is necessary to do a timely technical inspection of the entire car, including tires.

2. Inspect car tires monthly and, if suspicious changes are found, contact specialists at the service center.

3. Monthly (even more often) you need to check the pressure inside the wheels. And, if a discrepancy is found, eliminate it.

4. Every 15 thousand kilometers it is worth balancing the wheels.

5. Carefully inspect the surface of the tires for bumps and foreign objects after impacts and sudden movements on the roads.

6. If the wheels are changed, then it is imperative to maintain the original direction of their movement. Otherwise, additional wear of the tire surface will occur.

7. After repairing the steering gear or replacing the joints on the car, be sure to carefully check the wheel alignment, and also regularly monitor the clearances in the bearings and the presence of steering play.

8. Ensure the correct seasonal storage of rubber in the warehouse.

By following these simple rules, you can be sure that the life of your car tires will be as long as possible, and the process of driving will become more comfortable and safe.

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.
