1, inflationary pressure is too high. High air pressure can reduce tread contact area, reduce resistance and fuel consumption, and increase load capacity. Therefore, inflating air pressure is a necessary measure for trucks. The air pressure of the truck is 6- 10 kg, which is actually a time bomb.

2. If the wear is too large, it can't be replaced in time. Tire replacement accounts for more than 30% of the total maintenance cost, and a tire costs thousands of dollars! Buying a car is easier than maintaining it. Misers can save money by replacing worn tires with rear wheels and continuing to use them. In fact, it is to quench thirst by drinking poison.

3. overspeed and overload are the chief culprit of early tire damage. Racing, dangerous games and sudden braking on the expressway are easy to cause local high temperature, tire wear and puncture immediately.

4. The tire quality is poor, and hidden dangers such as retreading rubber, bulging, cracks, crevasses and low air pressure are not found in time. Driving around the car before driving was a slogan in the 1970s, but it is not so popular now. A flat tire has become an emergency, but it is actually ignorance or laziness.

5, poor driving skills, the sidewall was cut. At present, most tires are "vacuum tires"-tubeless tires, and they are no longer afraid of nails. Tire puncture is mainly due to poor observation, carelessness or underestimation. The side of the tire was cut by a sharp brick on the roadside, and the tire was punctured immediately.
