Why Do Cars Experience Tire Blowouts?
1 Answers
Reasons for vehicle tire blowouts: 1. Tire leakage: When punctured by nails or other sharp objects without immediate rupture, the tire may slowly leak air, eventually leading to a blowout. 2. Excessive tire pressure: During high-speed driving, tire temperature rises, increasing air pressure and causing deformation. This reduces the tire's elasticity and increases load stress, making it prone to internal cracks or blowouts upon impact. 3. Insufficient tire pressure: At high speeds (exceeding 120km/h), low pressure can induce "harmonic vibration" in the tire body, generating massive resonant forces. Weakened or damaged tires are particularly vulnerable to blowouts under these conditions. Additionally, underinflated tires exhibit greater tread deflection, making sidewall contact with the ground during sharp turns more likely. Since the sidewall is the tire's weakest area, such contact frequently results in blowouts.
