At what tire pressure level should the Haval F7 not be driven?
2 Answers
Haval F7 should not be driven when the tire pressure is below 1.7 bar. The optimal tire pressure should be maintained between 2.3-2.5 bar. Hazards of low tire pressure: The tires become softer, increasing the friction coefficient between the tires and the road surface, leading to higher fuel consumption. The part of the tire in contact with the ground deforms significantly, which over time can cause fatigue in the tire rubber and internal cord layers, affecting the tire's service life. It can also result in a heavy steering wheel and abnormal pulling, among other factors detrimental to driving safety. Hazards of excessive tire pressure: Vibration and pulling of the steering wheel, reduced ride comfort, decreased tire friction and adhesion, affecting braking performance. It accelerates localized wear on the central tread pattern of the tire, reducing the tire's lifespan.
Driving an SUV like the Haval F7, I believe you should never continue driving if the tire pressure drops below 2.0 bar. Last time, my car ran over a small stone on the highway, causing a leak that reduced the pressure to 1.7 bar. The whole vehicle was shaking violently, handling was completely out of control, and I almost rear-ended another car. The mechanic said that below this pressure, the tire sidewalls deform significantly, and the internal steel wires can twist and break, drastically increasing the risk of a blowout—especially in summer when road temperatures are higher, making accidents more likely. The standard pressure can be found on the door label; for the F7, it's around 2.3-2.5 bar, and it's best not to go below 2.0 bar. I recommend keeping a portable air pump handy and checking the pressure monthly—don’t take it lightly, as it could endanger both you and your passengers.
