What is the appropriate tire pressure for a cold car in winter?

[VonMaya]

In winter, when the car is cold, the front tire pressure of 2.2-2.3 bar and the rear tire pressure of 2.4-2.5 bar are within the normal range. The specific tire pressure should be based on the value indicated for each vehicle. According to the principle of thermal expansion and contraction, the tire pressure in summer can be 0.1-0.2 bar lower than the reference value in the manual, while in winter it can be 0.1-0.2 bar higher. The relevant details are as follows: 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. According to the regulations and requirements of the international GBT2978-2008 standard, the tire pressures for different tires are as follows: standard tires are 2.4-2.5 bar; reinforced tires are 2.8-2.9 bar; the maximum pressure should not exceed 3.5 bar. Abnormal tire pressure: Generally, an alarm will be triggered if the pressure is below 1.8 bar or above 3.0 bar. At this time, tire inspection and pressure adjustment are required.
