What is the standard tire pressure for cars?

[KendraLynn]

The standard tire pressure for cars is between 2.2bar and 2.5bar. The specific adjustment methods are as follows: 1. In winter, the tire pressure should be appropriately increased by about 0.2bar based on the standard tire pressure, while in summer, inflate to the lower limit of the standard tire pressure. 2. For empty or half-load conditions, use the lower limit of the standard tire pressure; for full load or heavy-duty conditions, use the upper limit. 3. The tire pressure differs between cold tires and hot tires, with a difference of about 0.3bar. 4. For long-distance high-speed driving, the tire pressure should not be too low; increase the tire pressure by about 0.2bar based on the lower limit of the standard tire pressure. 5. For new tires, increase the tire pressure by about 0.2bar based on the standard tire pressure, while for old tires, decrease the tire pressure based on the standard tire pressure.
