What is the normal tire pressure for sedans in summer and winter?

[GavinLee]

Normal tire pressure range in winter: In winter, the tire pressure should be based on the standard tire pressure of the car, with an appropriate increase of about 0.2bar. Normal tire pressure range in summer: Generally, the lower limit of the standard tire pressure of the car tire is sufficient. For example, the lower limit of standard tire pressure is 2.4bar. If the car is often parked outdoors, the tire pressure can generally be about 0.1bar lower than the standard to avoid tire blowouts due to high temperatures. According to the international GBT2978-2008 standard, the tire pressure for different tires is as follows: Standard tires: 2.4-2.5bar; Reinforced tires: 2.8-2.9bar; Maximum pressure: should not exceed 3.5bar. Tire pressure reset method: First, turn on the ignition switch, press and hold the tire pressure monitoring reset button, release it after hearing a "ding" sound, and the tire pressure monitoring system will store the current normal tire pressure data, automatically clear the original data, and finally the fault light on the dashboard will go out, and the tire pressure reset is completed.
