Causes of Tire Blowouts?

[LaEleanor]

Tire blowouts can be caused by both excessively high or low tire pressure. The normal tire pressure range is 2.4-2.5 bar. The causes of tire blowouts are as follows: 1. Tire leakage: When punctured by nails or other sharp objects without immediate rupture, the tire may gradually lose air, eventually leading to a blowout. 2. Overinflated tires: During high-speed driving, tire temperature rises, increasing air pressure and causing deformation. This reduces the tire's elasticity and increases the load on the vehicle. Any impact under these conditions can cause internal cracks or blowouts. This is also why blowout accidents frequently occur in summer. 3. Underinflated tires: When driving at high speeds (exceeding 120 km/h), insufficient tire pressure can cause "harmonic vibration" in the tire body, generating massive resonant forces. If the tire isn't strong enough or already damaged, it's prone to blowouts. Additionally, low pressure increases tire deflection, making the sidewalls more likely to contact the ground during sharp turns. Since sidewalls are the weakest part of a tire, such contact can also lead to blowouts.
