What Causes Abnormal Tire Pressure?
1 Answers
Tire pressure abnormalities can be caused by either overinflation or underinflation, and the vehicle should not be used in such conditions. To ensure driving safety, it is recommended to drive to the nearest tire repair shop for assistance. Hazards of Overinflation: Reduced tire friction and adhesion, affecting braking performance; Causes steering wheel vibration and deviation, reducing driving comfort; Accelerates wear on the central tread pattern, shortening tire lifespan; Increases vehicle vibration, indirectly affecting the lifespan of other components; Overstretches tire cords, reducing tire elasticity and increasing the load on the vehicle during driving; Decreases puncture resistance. Sharp objects like nails or glass can easily penetrate the tire, causing internal cracks or blowouts. Hazards of Underinflation: Increases friction with the road surface, leading to higher fuel consumption; Causes heavy steering and deviation, compromising driving safety; Increases movement in various parts of the tire, leading to abnormal heat due to excessive rolling; Weakens cord and rubber functionality, causing delamination or cord breakage and excessive friction with the rim, damaging the tire bead and causing abnormal wear; Multiplies friction between the tire and the ground, rapidly increasing tire temperature, softening the tire, and drastically reducing its strength. High-speed driving may lead to blowouts; Increases tire deformation, leading to sidewall cracks and flexing movements, causing excessive heat, rubber aging, cord fatigue, and breakage, while also increasing the tire's contact area and accelerating shoulder wear.
