Is a tire pressure of 3.0 bar normal for Wuling Hongguang?
2 Answers
If the tire pressure reaches 3.0 bar when the car is cold, it is slightly too high. If the tire pressure reaches 3.0 bar when the car is hot, it is considered normal. Hazards of excessive tire pressure: The friction and adhesion of the tires will decrease, affecting braking performance; It can cause steering wheel vibration and deviation, reducing driving comfort; It accelerates localized wear of the tread pattern in the center of the tire, reducing tire lifespan; Vehicle vibration increases, indirectly affecting the lifespan of other components; It causes excessive stretching and deformation of the tire cords, reducing tire elasticity and increasing the load on the car while driving; Puncture resistance decreases. When encountering sharp objects like nails or glass on the road, they can easily penetrate the tire, causing internal cracks or blowouts. Hazards of insufficient tire pressure: Friction with the road surface increases, leading to higher fuel consumption; It makes the steering wheel heavy and prone to deviation, creating unsafe driving conditions; It increases the movement of various parts of the tire, causing abnormal heat due to excessive rolling; It reduces the functionality of the cords and rubber, leading to delamination or cord breakage, and excessive friction with the rim, causing damage and abnormal wear at the bead area; Friction between the tire and the ground multiplies, causing a sharp rise in tire temperature, softening the tire and drastically reducing its strength. High-speed driving may lead to blowouts; It increases tire deformation, making the sidewalls prone to cracking and causing flexing movements, leading to excessive heat, accelerating rubber aging, cord fatigue, and breakage, while also increasing the tire's contact area and accelerating shoulder wear.
I've been driving a Wuling Hongguang for over a decade, and this tire pressure of 3.0 bar is slightly high. The normal range is generally between 2.2 and 2.5 bar. I recommend checking the owner's manual or the door label for confirmation. In the past, I tried driving long distances with overinflated tires, and the center of the tires wore out too quickly. The ride was uncomfortably bumpy, fuel consumption increased, and the tires tended to skid when turning in the rain, which wasn't very safe. Now, I go to the shop every quarter to get them checked and adjusted back to around 2.4 bar, which has significantly extended the tire lifespan. If you're unsure, just visit a reputable repair shop for a free pressure check. Maintaining proper tire pressure is crucial for vehicle durability and a comfortable driving experience—don't overlook major risks because of minor issues.
