Wuling Rongguang's tire pressure of 3.0 is not normal. According to tire pressure regulations and requirements, the standard tire pressure should be between 2.4-2.5 bar, and reinforced tire pressure should be between 2.8-2.9 bar. Therefore, a tire pressure of 3.0 is clearly too high. Hazards of Overinflated Tires: 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; Overextends 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, leading to internal cracks or blowouts. Hazards of Underinflated Tires: Increases friction with the road surface, leading to higher fuel consumption; Causes heavy steering and deviation, compromising driving safety; Increases movement of tire parts, leading to abnormal heat generation due to excessive rolling; Reduces the functionality of cords and rubber, causing delamination or cord breakage, and excessive friction with the rim, damaging the bead area and causing abnormal wear; Multiplies friction with the ground, rapidly increasing tire temperature, softening the tire, and drastically reducing 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.
