Four tires with different tire pressure

The tire pressure of the four tires is different, and the error is normal within 0.1 bar, and the five fingers are not necessarily long. However, it is not necessary to adjust the tire pressure if it exceeds 0.1 bar. Errors in tire pressure monitoring and different load conditions of the car may cause temporary changes in tire pressure.

1. The higher the temperature, the higher the tire pressure

According to the research data in "Tire Industry", the pressure of tires will increase with the increase of temperature. Every time the temperature rises by 30°C, the tire pressure will increase by 16.5%, and when the temperature rises by 40°C, the tire pressure will increase by 19.5%.

2. Exposure to the sun and water will affect tire pressure

For example, when parking, only one tire is exposed to the sun, and the black tire will absorb heat, so the temperature of this tire will be relatively high. In other words, if the tire is exposed to water, the water may dissipate some heat, and the temperature of the tire will be relatively low.

In addition, when the car turns sharply on the mountain road, the number of left turns and right turns is different, which will also cause the tire pressure on the left and right sides to be different, so there is no need to be so entangled.

3. The inflation composition of the tire will cause the tire pressure to be different

When the car is driving, the tire pressure will increase. Michelin said that it is generally 0.3 bar higher. But if one tire is re-inflated, the range of tire pressure change of this tire may be different from other tires.
