What is the acceptable tire pressure range for car tires?
1 Answers
Car tires can withstand a pressure range of 2.3 bar to 2.5 bar. Tire pressure is not constant; it increases as the tire temperature rises during driving. Strictly speaking, tire pressure refers to the air pressure inside the tire. Both overinflation and underinflation can shorten the tire's lifespan. Underinflation increases tire deformation, leading to cracks on the tire side due to excessive flexing, which causes overheating, accelerates rubber aging, fatigues the cord layers, and breaks the cords. It also increases the tire's contact area, accelerating shoulder wear. Overinflation causes excessive stretching of the tire cords, reducing the tire's elasticity and increasing the load on the tire during driving. In case of impact, it can lead to internal cracks or blowouts. Additionally, excessive pressure accelerates tread wear and reduces puncture resistance.
