Generally, the normal tire pressure should be between 2.2 and 2.5 kilopascals. In spring, when the temperature is around 20 degrees Celsius, the tire pressure is usually maintained at 2.3-2.5 kilopascals. 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. Tire pressure, strictly speaking, refers to the air pressure inside the tire. In terms of 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. Air pressure is the lifeblood of a tire. Both excessively high and low pressure can shorten the tire's lifespan. Low pressure increases the deformation of the tire body, making it prone to cracks on the sidewalls. It also causes excessive flexing, leading to overheating, rubber aging, fatigue of the cord layers, and even cord breakage. Additionally, low pressure increases the tire's contact area with the ground, accelerating wear on the tire shoulders. High pressure, on the other hand, overstretches the tire cords, reducing the tire's elasticity and increasing the load on the car while driving. In case of impact, it can cause internal cracks or even blowouts. High pressure also accelerates wear on the tread and reduces the tire's resistance to punctures.
