Low air pressure: will cause an increase in the width of the ground contact surface, which will exert excessive force on the edge of the tread. External wear can damage every part of the tire. In addition, compared to the optimal air pressure, low air pressure can also lead to an increase in sidewall inclination, which is very dangerous.

High air pressure: Due to the shape of the tire expanding, like a balloon, the force will be concentrated in the center position. Uneven force on the grounding surface will result in abnormal wear and tear.

Changlu Hong suggests that you check the tire pressure once a month.

The optimal air pressure level for your tires can be found on the inside of the car door, the inside of the vehicle fuel tank cap, or in the car manual.
