What is the standard tire pressure for passenger cars?
1 Answers
The tire pressure for passenger cars is as follows: 1. Normal conditions: The tire pressure for passenger cars is generally between 2.2 and 2.5 kPa under normal circumstances. 2. In spring: In spring, when the temperature is around 20 degrees Celsius, the tire pressure is usually maintained at 2.3-2.5 kPa. However, as the temperature and road surface temperature gradually rise, the tire pressure can easily increase during high-speed or long-distance driving, which may lead to tire blowouts. 3. In summer: In summer, the road surface temperature can reach 60-70 degrees Celsius. If the tire pressure is too high while driving, even a slight impact on a weak spot of the tire can easily cause a blowout. Information about tire pressure is as follows: 1. Tire pressure: Strictly speaking, it refers to the air pressure inside the tire. In car maintenance, the engine is the heart of the car, and its damage will lead to the end of the car's life. Similarly, tire pressure is the blood pressure of the car, and its level plays a crucial role in the performance and power of the car. 2. Air pressure: Air pressure is the lifeline of the tire. Both too high and too low pressure will shorten the tire's lifespan. Too low pressure will increase tire deformation, easily causing cracks on the sidewalls and generating flexing motion, leading to excessive heat, rubber aging, fatigue of the cord ply, and cord breakage. It also increases the tire's contact area with the ground, accelerating shoulder wear. Too high pressure will cause excessive stretching and deformation of the tire cords, reducing the tire's elasticity and increasing the load on the car during driving. In case of impact, it may cause internal cracks and blowouts. Additionally, excessive pressure accelerates tread wear and reduces puncture resistance.
