How much air pressure should be in tires?
1 Answers
Tire pressure is generally normal between 2.2-2.5 kPa. In spring, when the temperature is around 20 degrees, the tire pressure should be maintained at 2.3-2.5 kPa. However, as the temperature and road surface temperature gradually increase, especially during high-speed or long-distance driving, tire pressure can easily rise, increasing the risk of a blowout. In summer, road surface temperatures 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, 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. Similarly, tire pressure is like the blood pressure of the car, and its level plays a crucial role in the car's performance and power. 2. Air pressure is the lifeblood of the tire; both too high and too low can shorten the tire's lifespan. Low pressure increases tire body deformation, making the sidewalls prone to cracks and causing flexing movements, leading to excessive heat, rubber aging, fatigue of the cord layers, and cord breakage. It also increases the tire's contact area with the ground, accelerating wear on the tire shoulders. High pressure causes excessive stretching and deformation of the tire cords, reducing the tire body's elasticity and increasing the load on the car while driving. In case of an impact, it can lead to internal cracks and blowouts. Additionally, high pressure accelerates wear on the tire tread and reduces its resistance to being punctured.
