Why Do Cars Frequently Have Low Tire Pressure?
1 Answers
Tire pressure can be low for many reasons, mainly including damage to the car tires and slow leaks caused by tire aging. Hazards of Overinflated Tires: The friction and adhesion of the tires will decrease, affecting braking performance; it can cause steering wheel vibration and deviation, reducing driving comfort; it accelerates localized wear on the central tread pattern, shortening tire lifespan; increased body vibration indirectly affects the lifespan of other components; excessive stretching of tire cords can reduce tire elasticity, increasing the load on the car while driving; puncture resistance decreases. When encountering sharp objects like nails or glass on the road, they can easily penetrate the tire, causing internal cracks or blowouts, leading to tire bursts. Hazards of Underinflated Tires: The friction coefficient with the road surface increases, leading to higher fuel consumption; it makes the steering wheel heavy and prone to deviation, creating unsafe driving conditions; increased movement of tire parts causes excessive rolling, leading to abnormal heat generation; it reduces the functionality of cords and rubber, causing delamination or cord breakage, and excessive friction with the rim can damage the bead area, leading to abnormal wear; friction between the tire and the ground multiplies, causing a rapid rise in tire temperature, softening the tire, and drastically reducing its strength. High-speed driving can lead to tire bursts; increased tire body deformation can cause sidewall cracks and flexing movements, leading to excessive heat, rubber aging, cord fatigue, and breakage, while also increasing the tire's contact area with the ground, accelerating shoulder wear.
