The normal tire pressure for 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.

After years of driving, I prioritize tire pressure . The recommended tire pressure for Changan vehicles typically ranges between 2.3 to 2.5 bar, and may need adjustment to above 2.6 bar when fully loaded to prevent tire overload and wear. Abnormal tire pressure poses risks: too low increases the likelihood of overheating and blowouts at high speeds, while too high reduces grip, making the car prone to skidding in rainy conditions and compromising safety. I recommend a simple check every two weeks using an inexpensive handheld pressure gauge. Proper adjustment not only extends tire lifespan but also enhances handling stability, keeping accidents at bay.
