What are the hazards of abnormal tire pressure?
1 Answers
A car tire pressure of 2.0 bar is abnormal. The normal tire pressure range is between 2.2 to 2.8 bar. In winter, it should be appropriately increased by 2.0 bar, while in summer, it should be reduced by 1.0 bar. Hazards of overinflated tires: Tire friction and adhesion will decrease, affecting braking performance; it can cause steering wheel vibration and deviation, reducing driving comfort; it accelerates wear on the central tread pattern of the tire, shortening tire lifespan; vehicle vibration increases, indirectly affecting the lifespan of other components; it causes excessive stretching and deformation of tire cords, reducing tire elasticity and increasing the load on the car during driving; puncture resistance decreases. When encountering sharp objects like nails or glass on the road, the tire is more likely to be punctured, leading to internal cracks, blowouts, and tire bursts. Hazards of underinflated tires: Friction with the road surface increases, leading to higher fuel consumption; it makes the steering wheel heavy and prone to deviation, creating unsafe driving conditions; it increases the movement of various parts of the tire, causing abnormal heat due to excessive rolling; it reduces the functionality of the cords and rubber, leading to delamination or cord breakage, as well as excessive friction with the rim, causing damage to the bead area and abnormal wear; friction between the tire and the ground multiplies, rapidly increasing tire temperature, softening the tire, and drastically reducing its strength. High-speed driving may result in tire bursts; it increases tire deformation, making the sidewalls prone to cracks, generating flexing motion that causes excessive heat, accelerating rubber aging, cord fatigue, and breakage, while also increasing the tire's contact area with the ground and accelerating shoulder wear.
