Tires are circular elastic rubber products assembled on various vehicles or machinery for ground rolling. Usually installed on metal wheels, it can support the vehicle body, cushion external impacts, achieve contact with the road surface, and ensure the driving performance of the vehicle. Tires are often used in complex and harsh conditions, and they are subjected to various deformations, loads, forces, and high and low temperature effects during driving. Therefore, they must have high load-bearing performance, traction performance, and cushioning performance. At the same time, it is also required to have high wear resistance and flexural flexibility, as well as low rolling resistance and heat generation. Half of the world's rubber consumption is used for tire production, indicating the ability of tires to consume rubber.

After choosing the tires for your car, the most important thing is to maintain them during use. Among various car accessories, tires are relatively expensive, so it is particularly important to pay attention to the maintenance of car tires. The maintenance specialist of FAW Volkswagen Shida pointed out that tire maintenance should pay attention to the following points:

1. When driving at high speeds, maintain a safe distance between the vehicle and avoid unnecessary or frequent braking to reduce damage to the tires. At the same time, for safety reasons, pay attention to the depth of the tire tread. Tires that are close to being worn down have reduced friction with the road surface and longer braking distances, so do not drive at high speeds.

2. There is a one-to-one correspondence between tire load and air pressure. If the load is too high, it is similar to low air pressure, which can cause tire damage. Frequent use under overload can reduce the service life of tires by 20% -50%; At the same time, incorrect loading methods can also cause uneven tire load, affecting the lifespan of individual tires with excessive load.

3. Air pressure is the life of a tire, and the pressure it is inflated with must comply with the pressure specified by national standards for different types and specifications of tires. Regularly check the tire pressure, as both high and low pressure can cause irregular wear, cracks at the bottom of the grooves, broken cords, delamination of the curtain layer, tire bursting, and other damages; If you want to continue driving at high speeds, the air pressure should be increased by 5% -10% above the standard air pressure; At the same time, the tire will experience an increase in internal air temperature after driving, and it cannot be deflated at this time.

4. It is necessary to timely and appropriately rotate the tires on the vehicle (insist on checking the tires during the first and second level maintenance of the vehicle), maintain uniform wear of the tires, and extend their service life; Tires with slightly larger outer diameters should be installed on the outer wheel.

5. Do not use refurbished tires on the front wheels; Try to use tires with vertical stripes for the front wheels and horizontal stripes for the rear wheels.

6. If the tire is worn to the wear mark, it must be replaced.

7. In winter, due to relatively low temperatures, tires need to be inflated to maintain the specified pressure range. At the same time, tires should be checked for scratches, as rubber tires tend to become harder and brittle during autumn and winter, causing air leaks and even punctures. In addition, impurities in the tire tread should be regularly cleaned.
