The normal tire pressure for Changan vehicles is around 2.3-2.5 bar. According to the international GBT2978-2008 standard, the recommended tire pressures for different types of tires are as follows: Standard tires: 2.4-2.5 bar; Reinforced tires: 2.8-2.9 bar; Maximum pressure: should not exceed 3.5 bar. Hazards of overinflated tires: Reduced friction and adhesion of tires, 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; Excessive stretching of tire cords reduces elasticity, 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, leading to damage and abnormal wear; Multiplies friction between the tire and ground, rapidly increasing tire temperature, softening the tire, and drastically reducing strength. High-speed driving may cause blowouts; Increases tire deformation, leading to sidewall cracks and flexing, causing excessive heat, rubber aging, cord fatigue, and breakage, while also increasing the tire's contact area and accelerating shoulder wear.
