How much is the truck barometer normal?

Under normal circumstances, the tires of 4㎡ freight cars are compressed at high pressure, and the standard air pressure should be 5-7bar. If ordinary tires are used, the appropriate tire pressure value should be kept at about 5bar; If it is a stainless steel wire tire, the tire pressure value will be moderately increased, about 6bar. There may be some design errors due to different truck models. There will be a buzzer alarm in the high cab or low cab of the truck to remind the driver whether he can drive. The air pressure is too low, the brake system of the air brake cannot be released, and it is impossible to continue driving.

The following are the specific precautions for adjusting the tire pressure of truck tires:

1. Special circumstances: such as desert or mud, it is necessary to greatly reduce the tire pressure, because reducing the tire pressure can increase the contact area of the tire, reduce the pressure and reduce the chance of locking.

2. Always drive at high speed: In order to avoid standing waves in tires, the tire pressure can be appropriately increased.

3. Winter and summer: The tire pressure can be higher in winter and lower in summer to prevent high temperature puncture.

4. Low front tire pressure: Tire pressure is related to load. Due to the different body weight distribution, the recommended tire pressure of front tires, rear tires, half-load tires and full-load tires will be different. In addition, the air pressure of the front tire may be lower than that of the rear tire. Million car purchase subsidy
