Carry out tire transposition regularly. In order to maintain uniform tire wear on the same vehicle, the vehicle should do tire transposition every 5,000 kilometers and four-wheel positioning every 5,000 ~10,000 kilometers to avoid abnormal and excessive tire wear. It is not allowed to install tires with different models or large differences between old and new on the same axle.
Extended data:
Tire is one of the most important parts in a car. Its main functions are: supporting the overall weight of the car and bearing the load of the car; Transfer traction and braking torque to ensure the adhesion between the wheel and the road surface; Lighten and absorb the vibration and impact when the car is running, prevent the early violent vibration and damage of the car parts, adapt to the high-speed performance of the car and reduce the noise when driving, and ensure the driving safety, handling stability, comfort and energy saving and economy.
1, tire selection and installation
The correct installation of tires is directly related to the service life of tires, especially when replacing new tires. Tires of different types and patterns must not be mixed at will because of their different actual sizes and load capacity. In addition, if you can't fully master the skills of changing tires yourself, we suggest that you go to a professional tire shop or a specialized vehicle repairer for replacement.
2. Work pressure
Too low or too high tire pressure will affect the service life of tires. If the tire pressure is too low, its radial deformation will increase, and the deformation on both sides of the tire wall will be excessive, resulting in the wear of the tire crown and shoulder, which will increase the tire temperature and seriously reduce the service life of the tire.
If the tire pressure is too high, the tire rigidity will increase and the deformation and contact area will decrease, which will increase the unit pressure in the middle of the tread and aggravate the wear. The wear phenomenon in the center of the crown will affect the comfort and reduce the tire life. Experiments show that if the air pressure is increased by 25%, the tire life will be shortened by about 30%.
3. Tire load
There is no doubt that the greater the vehicle load, the shorter the tire life. Especially in the case of overload, it is more prominent. The tires produced by regular tire manufacturers are all marked with load index. Tires should be used within the maximum load range corresponding to the specified load index.
4. Driving speed
The tires produced by regular tire manufacturers are marked with speed grade index. Tires should be used within the maximum driving speed range corresponding to the specified speed grade index.
