What Causes a Car Tire Blowout?

[ORafael]

Tire pressure leading to blowouts. Below are the relevant explanations: Low pressure: When tire pressure is too low, the wheel's sinking amount increases, radial deformation enlarges, friction between the tire surface and the ground intensifies, rolling resistance rises, and the internal stress of the tire body also increases. This causes a sharp rise in tire body temperature, softening the tire surface rubber and accelerating the aging process, leading to local delamination of the tire body and increased wear on the tire surface. High pressure: Excessive tire pressure increases the tension of the tire body cords, accelerating the fatigue process of the cords. Especially when over-inflated and driving under overload and overspeed conditions, the internal stress of the cords further increases, rapidly raising the tire temperature. Tire imbalance: Incorrect tire installation occurs when some drivers do not properly check the spare tire to be replaced during tire changes. Due to uneven mass distribution around the wheel, when the wheel rotates, a significant impact force is generated in the wheel's rotational plane under centrifugal force, causing the wheel to jump and sway. This accelerates the wear rate of the tire.
