What are the reasons for low tire pressure in cars?
1 Answers
Tire pressure can be low for many reasons, mainly including damage to the car tires and slow air leakage due to aging of the car tires. Hazards of excessive tire pressure: Tire friction and adhesion will decrease, affecting braking performance; it can cause steering wheel vibration and deviation, reducing driving comfort; it accelerates localized wear of the tread pattern in the center of the tire, shortening tire life; increased body vibration indirectly affects the lifespan of other components; it causes excessive stretching deformation of the tire cords, reducing the elasticity of the tire body and increasing the load on the car while driving; puncture resistance decreases. When encountering sharp objects such as nails or glass on the road, they can easily penetrate the tire, and the impact can cause internal cracks and explosions, leading to a blowout. Hazards of insufficient tire pressure: The friction coefficient with the road surface increases, leading to higher fuel consumption; it makes the steering wheel heavy and prone to deviation, among other factors detrimental to driving safety; it increases the movement of various parts of the tire, causing abnormal heat due to excessive rolling; it reduces the function of the cords and rubber, leading to delamination or cord breakage, and excessive friction between the tire and the rim can damage the bead area, causing abnormal wear; friction between the tire and the ground increases exponentially, rapidly raising the tire temperature, softening the tire, and drastically reducing its strength. High-speed driving may lead to a blowout; it increases tire body deformation, making the tire side prone to cracks while generating flexing motion, leading to excessive heat, promoting rubber aging, fatigue of the cord layers, and cord breakage. It also increases the tire's contact area with the ground, accelerating shoulder wear.
