What is the appropriate tire pressure for light trucks?
2 Answers
For light trucks, the front tire pressure is suitable at around 9, and the rear tire pressure is suitable at around 11. Below is relevant information about tire pressure: 1. Excessive tire pressure: It will affect the tire's friction and adhesion, weakening the braking effect; it will cause car vibration, reducing comfort; it will accelerate wear on the central part of the tire, shortening the tire's lifespan; it will increase the load on the car while driving; it will reduce puncture resistance, making it easier for sharp objects like nails to penetrate the tire, causing a blowout. 2. Insufficient tire pressure: It will increase friction with the road surface, raising fuel consumption; the steering wheel will become heavier, making the car prone to veering; the tire's movement will increase, leading to abnormal heating; friction on the tire will intensify, shortening the tire's lifespan; the tire will become softer, reducing its strength, which may cause a blowout; cracks are more likely to appear on the tire side, promoting rubber aging and accelerating wear on the tire shoulder.
As a veteran truck driver with ten years of hauling experience, the tire pressure for light trucks isn't a fixed number. I've driven mainstream models like Foton Aoling and Dongfeng Dolica, and the difference in tire pressure between empty and fully loaded is significant. When empty, I usually inflate the front tires to 3.2-3.5 kg and the rear tires to 3.0 kg. But with a five-ton load, the rear tires need at least 4.2 kg, otherwise the sidewalls are prone to cracking. On summer highway runs, I deliberately reduce pressure by 0.2 kg to prevent blowouts from overheating. The most reliable method is checking the tire pressure label on the door frame - requirements vary by tire specifications. Remember to check cold tire pressure monthly with a mechanical gauge, as gas station pump gauges are often inaccurate.
