What are the effects of excessive tire pressure?

[MacJanelle]

The effects of excessive tire pressure are: 1. Increased friction between the tire and the ground, reducing tire adhesion and affecting the braking performance and driving comfort of the vehicle; 2. Accelerated wear of the central tread pattern, shortening the tire's service life; 3. Increased body vibration, accelerated tire aging, reduced wear resistance, and a higher risk of tire blowouts. The effects of insufficient tire pressure are: 1. Increased contact area between the tire and the ground, making the steering wheel heavier and affecting driving; 2. Tires are prone to overheating, leading to blowouts and expansion of the tire body; 3. Cracks are more likely to appear on the inner and outer sides of the tire, accelerating rubber aging and increasing tire wear.
