Why does the car show that the tire pressure is too high every time the weather gets warmer?

Gas expansion caused by tire inflation, high tire pressure, hot weather and high air pressure;

1, too high tire pressure will reduce tire friction and adhesion, affect braking effect and tire life;

2. Accelerate the local wear of tire tread pattern center, shorten tire life, increase body vibration, and indirectly affect the life of other components;

3. Too high tire pressure will also lead to excessive elongation and deformation of tire cords, reduce the elasticity of the carcass, increase the load when the car is running, and increase the rolling resistance.
