There are two main factors that affect the life of a tire:

1. Rubber aging.

The aging of rubber is mainly related to sunlight (ultraviolet rays), oxygen and ozone in the air, rain, snow, temperature, etc., rubber particles are oxidized in oxygen, corroded in rainwater, hardened and brittle at low temperatures, and will lead to rubber aging, hardening, and cracking for a long time, which can easily lead to punctures during driving.

2. Wear and tear. In the process of driving, the tire has been in a state of wear, under normal circumstances, after the tire is worn to the safety sign, its grip and displacement will decrease, reducing the driving stability.

Generally speaking, the service life of tires is 2-3 years or about 6-100,000 kilometers. However, for spare tires that have not been used for a long time, theoretically speaking, they should also be replaced, after all, the overall performance will also decline, and there may also be rubber aging.

Hello 1Tire selection and installation Correct tire installation is directly related to the service life of the tire, especially when replacing it with new tires.

Working Air Pressure If the tire pressure is too low or too high, it will affect the service life of the tire. If the tire pressure is too low, its radial deformation increases, and the deformation on both sides of the sidewall is excessive, resulting in wear on both shoulders of the crown and the tire.

Tyre load The greater the load on the vehicle, the shorter the life of the tyres. Especially in the case of overload, it is even more prominent.

Driving habits are factors that are directly related to the owner of the car. Starting too hard, swerving, braking suddenly, driving at high speeds in bad road conditions.

1.The correct tire installation is directly related to the service life of the tire, and the actual size and load capacity of the tire with different types and patterns are different.

2.If the tire pressure is too low or too high, it will affect the service life of the tire.

3.The greater the load on the vehicle, the shorter the life of the tires. Especially in the case of overload, it is even more prominent.

4.If the vehicle is driven on gravel roads or in bad road conditions for a long time, the service life of the tires will definitely be reduced.

Tires are ring-shaped elastic rubber products that are grounded and rolled on various vehicles or machinery. Usually installed on the metal rim, can support the body, cushion the external impact, realize the contact with the road surface and ensure the driving performance of the vehicle. So what are the factors that affect the life of tires?

Let me take you to find out!

As one of the important components of the car, tires are of decisive significance to driving safety. So what is the basic lifespan of a tire?

The life of a tyre is related to many factors, such as climate, road, driving style, installation, maintenance and repair. According to international regulations, if the tire is used normally, the tire must be replaced when it is ground to a tread depth of millimeters. In general, the life of tires can be judged from the following information:

The tread height of the tyre is less than 1 mm, or the markings for replacing the tyre with a new one are worn out. From the perspective of kilometers, ordinary tires can generally be used for 5-100,000 kilometers if they are used normally, and it is recommended to do dynamic balancing every 10,000 kilometers for tire transposition if necessary, and 10,000 regular inspection and maintenance items include transposition, tires need to be checked frequently, and tire wear will be aggravated if it is too low or too high; Removal of relatively large stones; Four-wheel alignment every 20,000 kilometers, etc.; Ordinary tires are valid for five years after production, so they must be replaced after four to five years of use, regardless of whether they are worn to the millimeter. In addition, if a tyre fails, such as a cut on the sidewall, it must be replaced immediately.

Regarding tire maintenance, it is recommended that you check the tires every month or before going out for long distances, especially whether the side of the tire is bulging or cracked. Note: The side of the tire is the weakest, so don't let it rub against the road. Be sure to stop in a shady place in the summer.

Automobile tires are the only parts of the vehicle in contact with the road, and tire maintenance is directly related to the service life of the vehicle. Tire pressure, tire load, driving speed, and road conditions can all affect the life of a tire. Tires should be used within the maximum load capacity corresponding to the specified load index.

Tire wear factors are closely related to the tire material brand, each tire brand has a corresponding label, now the more wear-resistant tires are Goodyear, Dunlop and other tires, these are household inclusive tires, although the tires are wear-resistant, but the tire noise and vibration are also large, and the ride comfort is poor, so most of the operating vehicles will choose these tires.

Tire use time, tire life tires are composed of rubber materials, rubber has a shelf life, the longer the time, the more serious the rubber aging, which naturally leads to a significant reduction in tire life. If some people rarely drive, 5,000 kilometers a year, 5 years 10,000 kilometers, such a tire surface will crack, and it is safer to replace the tire as soon as possible.

The impact of tire pressure, tire service life, the impact of tire pressure on the life of car tires, is exactly the same as that of bicycles, only the tire pressure is appropriate, and the tire life will be longer. The greater the tire pressure, the smaller the contact area between the tire and the ground, local wear will occur in the middle of the tire, and the tire life will be reduced; If the tire pressure is too low, the position of the tire shoulder is in greater contact with the road surface, and the tire shoulder will be severely worn on both sides, and the tire life will be significantly reduced.

The factors that affect the service life of tires are mileage, road surface temperature, air pressure, working conditions, ambient temperature, sunlight, etc. The tires are the only part of the car that is in contact with the ground. Tires are related to the driving stability and safety of the car, and are very important to the car.

Tires are rubber products, which will age and wear out after long-term use, and need to be replaced regularly.

Generally, tires installed on a car can last for four years, so it is recommended that you replace your tires every four years.

And when buying new tires, be sure to read the production date clearly, because tires have a shelf life.

In general, the shelf life of unused tires is three years. If it's been more than three years since it left the factory, don't buy it.

After installing the new tires, be sure to re-check the dynamic balance of each wheel to prevent abnormal wheel shaking at high speeds.

If the wheels shake abnormally at high speeds, it will affect the driving stability and handling of the car.

Always check the tire pressure when using the car.

Air pressure is important for tires, and the tire pressure should not be too high or too low.

If the air pressure is too high, the grip will be reduced.

If the air pressure is too low, it will cause the tires to deform in waves at high speeds.

The tires of the car are one of the important parts of the car, which is related to the safety of driving the car, so what are the factors that affect the service life of the tire?

The service life of a car tire is affected by factors such as tire load, tire pressure, car speed, road conditions, etc. The wear and tear of tires is also related to the brand and material of the tire, and the more wear-resistant tires are Dunlop, Goodyear, etc., as well as inclusive tires, which are also very wear-resistant, but the tires of this brand vibrate a lot and make a lot of noise, and few car owners and friends will choose this kind of tire.

The material of automobile tires is rubber, and the longer the use of rubber, the more serious the aging, so the tires have a service life, and the aging tires are easy to crack, which is a threat to the safety of driving.

When choosing car tires, it is necessary to choose tires that meet the load index, that is, the tires should be used within the specified load index. There is also the right tire pressure when driving the car, the driving speed should not be too fast, and the road surface is as good as possible, so as to extend the service life of the tire as much as possible.

1 barometric pressure. The inflation pressure of the tire is determined through a series of calculations and tests according to the allowable quality of the tire, the type of tire and the characteristics of use, and cannot be changed at will. The tire pressure should be kept at a standard value, and too low or too high air pressure will bring serious harm to the tire.

If the air pressure is too low, the stiffness of the tire will decrease, and the deformation area and degree of deformation of the tire will increase. Causes tires to heat up, causing early damage such as cord fatigue, carcass delamination, and accelerated shoulder wear. When the tire inflation pressure is too high, the area of contact between the middle of the crown and the road surface is small, which increases the pressure of the ground contact area, which accelerates the wear in the middle of the crown.

In addition, due to the high air pressure, the tire is stiff and the elasticity is reduced, so that the cord is overstretched, which is easy to cause early damage or bursting of the tire, especially in summer. Therefore, the tire pressure must be checked frequently and replenished in time to make the air pressure meet the standard and remain unchanged, which is an important measure to eliminate the hidden dangers of tires. In terms of specific applications, it should be appropriately adjusted according to the tire installation position and actual load.

If the tractor front axle load is lower than the maximum load of the two front tires, the tire pressure can be reduced by 03 MPa according to the standard; For vehicles with a front axle load close to the maximum load on the two front tyres, the tyre pressure must be sufficient according to the standard.

2 Load. The load of the tire is calculated based on the structure of the tire, the strength of the carcass cord, and the inflation pressure and speed during use. Tire life is doubled when the tire load is 30% lower than the maximum allowable value, and 50% and 66% shorter when the tire load is 40% and 80% overloaded, respectively.

The tractor should be loaded according to the tonnage specified by the original factory, and increasing the load capacity at will will overload the tires, increase the deformation, and produce harmful stress. At the same time, the contact area between the tire and the ground increases, resulting in an increase in wear, which heats up the tire and increases the tire temperature, which not only accelerates the tire wear but also reduces the strength of the cord, and if it encounters the impact of obstacles, it is more likely to be damaged. If the tires are overloaded by 20%, the mileage will be reduced by 35%; If the overload is doubled, it will be reduced by more than 80.

There are many factors that cause tire overloading: some are loaded with more than tonnage, and some are improperly loaded and unevenly distributed.

There are many factors influencing the life of car tires, the most important of which is the way of maintenance and the way of correct driving. Therefore, in the process of driving, we must pay attention to learning and mastering skills from professional technicians, so as to be more conducive to the quality assurance of automobile tires.

Car tires have a certain service life, and under normal circumstances, original tires can run 6 to 80,000 kilometers, or use for 3 to 5 years. The tire is an important part of the car, the only part of the car that is in contact with the ground, and the tire is related to the driving stability and driving safety of the car.

1. The quality of the tires.

2. The weight of the rider.

3. Riding on the road surface.

4. Usual maintenance of tires.

"In the early stage, the main thing is to prevent the occurrence of seedling diseases due to excessive humidity in the seedbed, and it is necessary to ventilate frequently to reduce the air humidity and soil moisture of the seedbed. In the later stage, water shortage is generally used to water appropriately in the morning on a sunny day, and it cannot be flooded. 3 to 4 days before seedling, ventilation and cooling and water control, proper exercise of seedlings, improve the adaptability of seedlings. ”

1. Optional and installation of tires.

Correct tire installation is directly related to the service life of the tire, especially when replacing it with a new tire. Tires with different types and patterns must not be mixed arbitrarily due to the actual size and load capacity of each tire.

2. Working air pressure.

If the tire pressure is too low or too high, it will affect the service life of the tire. If the tire pressure is too low, its radial deformation increases, and the deformation on both sides of the sidewall is excessive, resulting in the wear of the crown and shoulders, which increases the temperature of the tire and seriously reduces the service life of the tire.

3. Tire load.

There is no doubt that the heavier the load on the vehicle, the shorter the life of the tyres. Especially in the case of overload, it is even more prominent. The tires produced by regular tire manufacturers are marked with a load index. Tires should be used within the maximum load capacity corresponding to the specified load index.

4. Driving habits.

This is a factor that is directly related to the owner of the car. Excessive starting, sudden steering, emergency braking, driving at high speeds in bad road conditions, frequent getting on and off the road, and scratching obstacles when parking can all lead to severe wear and tear on the tires, which in turn reduces the service life of the tires.

5. Road conditions.

If the vehicle is driven on gravel roads or in bad road conditions for a long time, the service life of the tires will definitely be reduced. This is no different for off-road vehicle tires.

Tire load. There is no doubt that the heavier the load on the vehicle, the shorter the life of the tyres. Especially in the case of overload, it is even more prominent.

The tires produced by regular tire manufacturers are marked with a load index. Tires should be used within the maximum load capacity corresponding to the specified load index.

Travel speed. The tires produced by regular tire manufacturers are marked with a speed class index. Tires should be used within the maximum driving speed corresponding to the specified speed class index.

Tire temperature. During the driving of the vehicle, the tire temperature rises due to extension, compression and friction. Excessively high temperatures can easily exacerbate tire wear and even puncture.

Tire precautions.

Avoid excessive tire pressure: It should be noted that each automobile manufacturer has special regulations on tire pressure, please follow the signs and do not exceed the maximum value. If the air pressure is too high, the weight of the body is concentrated on the center of the tread, causing the center of the tread to wear out quickly.

When impacted by external forces, it is easy to cause trauma and even burst the tread; Excessive tension causes tread delamination and tread groove bottom cracking; Tire grip is reduced, braking performance is reduced, vehicle runout, comfort is reduced, and vehicle suspension systems are easily damaged.
