What is the Suitable Tire Pressure?
1 Answers
Tire pressure is generally considered normal between 2.2―2.5 kPa. In spring, when the temperature is around 20 degrees Celsius, the tire pressure should be maintained at 2.3-2.5 kPa. However, as the temperature and road surface temperature gradually rise, especially during high-speed or long-distance driving, the tire pressure can easily increase, which may lead to tire blowouts. 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. Here is some information about tire pressure: 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 pressure will shorten the tire's lifespan. Low pressure increases the deformation of the tire body, making it prone to cracks on the sidewalls and causing flexing movements, leading to excessive heat generation, 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, on the other hand, 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 rolling.
