Why does tire pressure suddenly increase?

一、Why does the tire pre ssure increase on its own?
There are usually two reasons for high tire pre ssure:
1. Too much air is inflated during inflation, causing the air pre ssure to be too high. If the tire pre ssure is too high, sharp objects on the road (such as nails, glass, etc.) can easily penetrate the tire and even cause a tire blowout.
Solution: In this case, just use a barometer to release some of the air pre ssure.
2. After a car is driven for a long time, the tire pre ssure will increase. This is due to the expansion of gas caused by the increase in tire temperature.
Solution: In this case, there is no need to deflate immediately. Because the tire pre ssure may be normal, hot car tire pre ssure is usually 40 to 60 kPa higher than cold car tire pre ssure.
Generally speaking, 230 to 250 kPa is the normal tire pre ssure range for ordinary cars. We can find the appropriate tire pre ssure for our vehicle by looking in the vehicle owner's manual, on the label next to the driver's door, or on the inside of the fuel tank cap.
Car tire pre ssure is very important. Research shows that many car failures are actually caused by unreasonable tire pre ssure.
The impact of abnormal tire pre ssure on vehicles:
1. Tire pre ssure will affect the fuel consumption of the car. A vehicle with too low tire pre ssure will consume more fuel than a vehicle with normal tire pre ssure.
2. Too low tire pre ssure will cause excessive wear on both sides of the tire and affect tire life.
3. Excessive tire pre ssure will also cause excessive wear of the middle part of the tire and reduce tire life.
4. Whether it is high tire pre ssure or low tire pre ssure, it may cause a tire blowout accident in the vehicle.
5. When the tire pre ssure is too high, the driving experience will be affected. Because the tires become more rigid, the vehicle's vibration frequency and intensity will increase.
6. Low tire pre ssure cannot ensure normal contact between the tread and the road. During emergency braking, the tire contact area becomes smaller and the braking performance is reduced.
7. When the tire pre ssure is too high, the braking distance will be longer when emergency braking on a road with low adhesion, making a rear-end collision prone to occur.
