What is the Maximum Pressure a Car Tire Can Withstand?
2 Answers
Tire pressure is generally considered normal between 2.2 and 2.5 kilopascals. In spring, when the temperature is around 20 degrees Celsius, the tire pressure should typically be maintained between 2.3 and 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 slight contact with weak spots on 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 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. The level of tire pressure plays a crucial role in the car's performance and power. 2. Air pressure is the lifeline of a tire. Both too high and too 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 flexing movements, leading to excessive heat, rubber aging, fatigue of the cord layers, and cord breakage. Additionally, it 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. This increases the load on the car while driving, and impacts can lead to internal cracks and blowouts. High pressure also accelerates wear on the tire tread and reduces its resistance to rolling.
When I drive my sedan, I always pay attention to the tire pressure. The maximum pressure a sedan tire can withstand is usually between 35 to 44 psi, which is approximately 2.4 to 3.0 bar. The exact value can be found on the sidewall of the tire, like on my car where it says 'max press 44 psi'. However, this is not the pressure you should use daily; it's just the upper limit. If the pressure is too high and exceeds this number, the tire is more likely to burst or lose control at high speeds. Underinflation also causes problems. Last time I neglected it, the pressure was only 25 psi, resulting in faster wear on both sides of the tire and increased fuel consumption. I recommend maintaining the manufacturer's recommended pressure, usually between 30 to 35 psi, which can be found on the door frame or in the user manual. Temperature changes affect tire pressure; it rises in the summer heat and drops in the winter cold. Checking it every two weeks with an inexpensive pressure gauge takes just a few minutes and ensures safe driving.
