When driving, the Petrol Car tires heat up due to friction with the ground, and the gas inside the Petrol Car tires will also expand. Especially in summer, excessive pressure in the Petrol Car tires can easily cause the Petrol Car tires to deform, and the elastic strength of the tire body will decrease. In addition, the impact of the road surface and the body load are more likely to cause a tire blowout.
When the tire pressure is insufficient, the contact area between the Petrol Car tire and the ground will increase, increasing the friction and causing increased fuel consumption. When the tire pressure is insufficient, the Petrol Car tires will become soft, which does increase the comfort, but the handling performance will deteriorate, because the Petrol Car tire wall will shake more due to the lack of gas support.
Because most Changan Car currently use tubeless radial tires, when driving with low air, the friction increases, and the Petrol Car tires will heat up seriously. In addition, the steel wires in the tire body will rub against each other, accelerating the deformation of the Petrol Car tires and the decrease in the strength of the steel wires. Moreover, too low tire pressure will also cause the tire wall, the weakest part of the Petrol Car tire, to contact the road surface, all of which are the root causes of tire blowouts.
Too low or too high tire pressure in a Petrol Car can cause a tire blowout, and the consequences of a tire blowout are often very serious. A Petrol Car traveling at high speed will lose control or even overturn if it encounters a tire blowout. Data shows that when a Petrol Car is traveling at a speed exceeding 120 kilometers per hour, the mortality rate if a Petrol Car encounters a front tire blowout is almost 100%.
