Tire pressure should not be too high or too low. Abnormal tire pressure will reduce the performance of the car more or less, and in serious cases, it will lead to a flat tire and threaten personal safety. There is a clear standard tire pressure in the world. Generally speaking, the tire pressure of standard tires should be 2.4-2.5 bar;
The tire pressure of reinforced tires should be 2.8-2.9 bar; However, no matter what kind of tire, the tire pressure can't be higher than 3.5bar. At the same time, the tire pressure will be affected by seasonal temperature, road conditions, vehicle load and other factors, so the car should be adjusted appropriately.
Extended data:
Tire pressure identification is introduced as follows:
When the tire pressure is too high, the tire cord will be excessively stretched and deformed, and the middle of the tread will bulge, resulting in serious wear in the middle of the tire; The contact area with the ground is reduced, the adhesion is reduced, the car is more likely to slip, and the braking distance will be extended. At the same time, the tire rigidity increases and the dynamic load of the wheel increases, which is easy to cause tire puncture.
In addition to tire pressure, tire identification also includes production number, manufacturer's trademark, size specification, grade and so on. The material of carcass cord fabric is expressed in Chinese Pinyin, and cotton cord fabric is expressed in M; Rayon cord fabric is denoted by R; The steel cord fabric is denoted by G, and the radial tire is denoted by ZG.
What is the standard of normal tire pressure? Old driver: Don't be silly. Turn it to 2.5.
