What Are the Consequences of Excessive Tire Pressure?

[McEvelyn]

The following are the hazards of excessive tire pressure: 1. Reduced tire friction and adhesion, affecting braking performance; 2. Causes steering wheel vibration and deviation, reducing driving comfort; 3. Accelerates localized wear of the tread pattern in the center of the tire, shortening tire lifespan; 4. Increases vehicle body vibration, indirectly affecting the lifespan of other components; 5. Overextends the tire cords, reducing tire elasticity and increasing the load on the vehicle during driving; 6. May lead to tire blowout. The hazards of insufficient tire pressure: 1. Increases the friction coefficient with the road surface, leading to higher fuel consumption; 2. Makes the steering wheel heavy and prone to deviation, posing safety risks; 3. Increases movement in various parts of the tire, causing abnormal heat due to excessive rolling; 4. Reduces the functionality of the cords and rubber, leading to delamination or cord breakage and excessive friction with the rim, causing damage to the bead area and abnormal wear; 5. Multiplies the friction between the tire and the ground, sharply increasing tire temperature, softening the tire, and drastically reducing its strength. High-speed driving may result in a blowout; 6. Low tire pressure increases tire deformation, making the sidewalls prone to cracks and generating flexing motion, leading to excessive heat, rubber aging, cord fatigue, and breakage, while also increasing the tire's contact area with the ground, accelerating shoulder wear.
