Is a tire pressure of 2.2 normal for a sedan?
1 Answers
Tire pressure between 2.2~2.5 bar is considered normal. Additional information about tire pressure is as follows: 1. Insufficient tire pressure will increase tire body deformation, leading to issues such as cracks on the tire sidewalls, excessive heat generation, and accelerated rubber aging. It also increases the tire's contact area with the ground, speeding up wear on the tire shoulders. Excessive tire pressure will cause excessive stretching deformation of the tire cords, reducing the elasticity of the tire body and increasing the load on the car during driving. 2. Strictly speaking, tire pressure refers to the air pressure inside the tire. There is a label on the rear end of the driver's side door indicating the standard tire pressure, which is the pressure when the tire is cold, i.e., after the car has been parked for at least three hours or driven no more than 1.6 km. The most accurate tire pressure measurement is taken when the tire is cold.
