What is the normal range for car tire pressure?

[BethanyRose]

The standard tire pressure for passenger cars is normally in the range of 2.3-2.5 bar, with a maximum not exceeding 3.0 bar and a minimum not below 2.1 bar. According to the international GBT2978-2008 standard requirements, the tire pressure for different tires is as follows: Standard tires: 2.4-2.5 bar; Reinforced tires: 2.8-2.9 bar; The maximum pressure should not exceed 3.5 bar. Normal tire pressure in winter: In winter, the tire pressure should be based on the standard tire pressure of the car tire, with an appropriate increase of about 0.2 bar. Normal tire pressure in summer: Generally, the lower limit of the standard tire pressure for car tires is sufficient. For example, the lower limit for standard tires is 2.4 bar. If the car is often parked outdoors, the tire pressure can generally be about 0.1 bar lower than the standard to avoid tire blowouts due to high temperatures.
