Why Do Cars Get Flat Tires on Highways?
1 Answers
High-speed driving can easily lead to tire blowouts due to reasons such as speeding, poor road conditions, or tire pressure not meeting safety requirements. Below is a detailed explanation of why high-speed driving can cause tire blowouts: 1. Under-inflation: When tire pressure is too low, the wheel's sinking amount increases, radial deformation increases, friction between the tire surface and the ground increases, rolling resistance rises, and the internal stress of the tire body also increases. This causes the tire body temperature to rise sharply, the tire surface rubber to soften, and the aging speed to accelerate. 2. Over-inflation: Excessive tire pressure increases the tension of the tire body cords, accelerating the fatigue process. Especially when driving with over-inflation, overload, and overspeed, the internal stress of the cords increases, tire temperature rises rapidly, rubber aging speeds up, fatigue strength decreases, leading to severe wear on the central part of the tire tread and sawtooth-like wear on the side patterns, resulting in blowouts. 3. Incorrect tire installation: Wheel imbalance causes uneven mass distribution. When the wheel rotates, under centrifugal force, a huge impact force is generated in the wheel rotation plane, causing the wheel to jump and sway, thereby increasing the tire wear rate.
