Is the tire pressure alarm normal when the weather is cold?

Some car owners are puzzled to find that their cars occasionally have tire pressure lights on in winter. So is the tire pressure alarm normal when the weather is cold?

1, tire pressure alarm is a normal phenomenon in cold weather, so car owners don't have to worry too much.

2. Because the temperature is relatively low, the air in the tire will be reduced by the influence of cold air, and the tire pressure will give an alarm when it decreases. Don't worry too much, you can inflate it properly to keep the tire pressure within the normal range; The tire pressure will decrease in winter, so the tire pressure value can be increased by about 0.2 when inflating, and the four tire pressures should be kept in the same range as far as possible.

3. Because the temperature is relatively high in summer, the air in the tire will also be affected by high temperature, which will lead to the increase of tire pressure, so the cold tire pressure in summer is lower, and it is more appropriate to reduce it by 0.2 on the basis of normal value. If the tire pressure is too high in summer, it may cause high temperature puncture.

Under normal circumstances, the tire pressure of the car is between 2.3 and 2.5 bar. 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.
