Is the tire pressure abnormal? Is the tire punctured?

The car tire pressure monitoring system shows that the abnormal tire pressure does not necessarily mean that the car tires are broken. It may be that the car tires are leaking, the rim is deformed, the tire pressure is too high or too low, etc., resulting in a decrease in the sealing performance of the car tires.

When the tire pressure of the car is 2.7, the car driving can have the effect of saving fuel, but the shock absorption effect of the tire is not obvious, resulting in a strong road feeling for the people in the car. The tire temperature of a car on the highway is about 50 degrees Celsius. Due to thermal expansion and contraction, it is normal for the tire pressure to increase due to the increase in temperature. The normal tire pressure is about 2.5. I am really worried that the high tire pressure will cause safety hazards. You can drive the car into the service area of ​​the expressway and release some air from the tires to keep the tire pressure at about 2.5, making the car the most fuel-efficient driving. The state is also the most comfortable state of the car.
