What is the normal car tire pressure?

[Samuel]

Car tire pressure is normal between 2.2 to 2.5 bar. Factors affecting car tire pressure include: 1. Seasonal factors: The pressure will be slightly higher in winter and slightly lower in summer, usually with a difference of plus or minus 0.2; 2. Load factor: When the car is unloaded, the lower limit of the standard car tire pressure should be used as the reference for the minimum tire pressure. When the car is fully loaded, the upper limit of the standard car tire pressure should be used as the theoretical reference for the maximum tire pressure. The hazards of excessive tire pressure include: 1. It will reduce the friction and adhesion of the tire, affecting braking performance; 2. Accelerate the local wear of the tread pattern in the center of the tire, which may easily lead to tire bulging; 3. Cause steering wheel shaking and deviation.
