What Are the Causes of Overinflated Tire Pressure?
1 Answers
Reasons for overinflated tire pressure in vehicles: 1. Excessive tire inflation leading to high tire pressure readings; 2. Imbalanced tire dynamics with excessive deflection, causing increased tire wear temperature and elevated tire pressure; 3. Inaccurate wheel alignment (four-wheel alignment) of a particular wheel, resulting in uneven tire wear, higher temperature, and increased tire pressure; 4. Aging and wear of suspension components connected to the wheels, leading to misalignment, increased uneven wear temperature, and higher tire pressure. Hazards of overinflated tire pressure: 1. Overinflated tires reduce friction and adhesion, impairing braking effectiveness and shortening tire lifespan. 2. Overinflation decreases puncture resistance, increasing the risk of tire blowouts. 3. Accelerates localized wear of the central tread pattern, reducing tire life, increasing vehicle vibration, and indirectly affecting the lifespan of other components. 4. Overinflation causes excessive stretching deformation of tire cords, reducing tire elasticity and increasing the load borne by the vehicle during driving, thereby decreasing resistance to rolling. 5. When encountering sharp objects like nails or glass on the road, tires are more prone to punctures, leading to internal cracks and blowouts upon impact.
