What happened to the tire pressure alarm when it was cold?

For people who often use cars, they usually pay more attention to the tire pressure problem, because once the tire pressure value is too high or too low, it will increase the driving risk. Some car owners found that the weather gets cold in winter and the tire pressure will call the police. So what about the tire pressure alarm when the weather is cold?

1. The reason why the tire pressure will give an alarm when the weather is cold is because the air in the automobile tire will be less affected by the temperature as the weather gets cold, which may cause the tire pressure to drop and give an alarm, so it is normal for the tire pressure to give an alarm when the weather is cold. Don't be too nervous. Then inflate the tire, increase the tire pressure and return to normal.

2. Under normal circumstances, the tire pressure of an automobile is between 2.3 and 2.5 bar, and it needs to be raised in winter and lowered in summer to avoid tire puncture caused by excessive temperature. Although the tire pressure drop in winter is normal, it should not be too low, because it will accelerate the contact area between the tire and the ground, resulting in serious tire wear, thus shortening the service life.
