What is the standard tire pressure?
2 Answers
Standard tire pressure: The standard tire pressure for standard tires is 2.4 to 2.5 bar; for reinforced tires, it is 2.8 to 2.9 bar, with the maximum pressure not exceeding 3.5 bar. Tire pressure refers to the air pressure inside the tire. In car maintenance, the engine is the heart of the car, and its damage can lead to the end of the car's life. Tire pressure is the blood pressure of the car, and its level has a significant impact on the car's performance and power. Air pressure is the lifeblood of the tire; both too high and too low will shorten the tire's lifespan. Low pressure increases tire body deformation and is prone to sidewall cracking. High pressure causes excessive stretching and deformation of the tire cords, reducing the tire's elasticity and increasing the load on the car during driving.
It depends on the car model. My own car has a small label on the door frame indicating 2.4 for the front tires and 2.2 for the rear tires (unit is bar). However, the mechanic during the last service mentioned that in summer, it should be reduced to 2.3 for highway driving, and in winter, it should be increased to 2.5. A word of caution: the free air pressure gauges at gas stations are often inaccurate. I keep a 20-yuan digital tire pressure gauge in the glove box and check it before every long trip. The most accurate reading is when the tires are cold. After a highway drive, wait for the tires to cool down before measuring, as hot tire pressure is about 0.3 higher than cold tire pressure.
