Will the air pressure of automobile tires become lower in cold weather?

Will decrease. In cold season, when inflating vehicle tires, it is usually about 0.2bar higher than the standard value. Because the tire will expand with heat and contract with cold in winter, if the tire pressure value is not properly improved, it will increase tire consumption; But it can't be adjusted too much, which is easy to weaken the braking performance. According to the suggestions of various automobile manufacturers, in order to ensure driving safety, it is suggested that the owner check the air pressure values of the four tires of the vehicle every week, but it must be checked on the premise of cold tires, otherwise the data will be inaccurate; The advantages of regularly checking the tire pressure value are: 1. Ensure driving safety; 2. Ensure that the tire pressure value is sufficient, so as to ensure that each tire is in full contact with the ground, ensure the comfort of drivers and passengers, and save fuel.
