What Should the Tire Pressure Be?
1 Answers
Tire pressure is generally normal between 2.2―2.5 kPa. In spring, when the temperature is around 20°C, 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, the tire pressure can easily rise, increasing the risk of a blowout. In summer, road surface temperatures can reach 60-70°C. 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 are some details 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—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 lifeline of the tire—both too high and too low 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, rubber aging, fatigue in 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, overextends the tire cords, reducing the elasticity of the tire body and increasing the load on the car while driving. In case of impact, it can cause internal cracks and blowouts. Additionally, high pressure accelerates wear on the tire tread and reduces its resistance to punctures.
