It's very cold. Why is the tire pressure suddenly less?

1, which is due to the characteristic that steam expands with heat and contracts with cold, and the low tire pressure is partly related to the cold weather. When the weather is cold, the tire pressure will decrease.

However, there are other factors for low tire pressure. For example, air leakage will also make the tire pressure too low. When the tire is punctured, it will cause air leakage, and when the car is naturally brittle or the parking time is too long, the exhaust will be slow.

3. When the tire pressure is too low due to the cold temperature, it can be inflated moderately or ignored. If the temperature turns cold for a long time, be sure to pump air moderately. If the average temperature drops only for a short time, it can be ignored until the temperature rises, and the tire pressure will also rise.

Extended data:

1. In car maintenance, the engine is the heart of the car, and the damage of the engine will lead to the exhaustion of the life of the car, so the tire pressure is the blood pressure of the car, and the level of tire pressure plays a vital role in the performance and power of the car.

2. Car load depends on tire pressure. According to the relationship between tire load index and tire pressure and tire load capacity, the higher the tire pressure, the greater the load capacity, and the smaller the air pressure, the smaller the load capacity.
