1. Overload
Overloading is one of the main causes of burning toe mouth. Overloading of trucks and buses in our country has been repeatedly banned. Overloading will put more pressure on the tires, resulting in greater friction with the wheels and more serious heat generation of the wheels. Coupled with long-distance driving, it will Tire burn toe problem occurred.
In the hot summer weather, the heat dissipation of the wheel itself is slow, and overloading makes the temperature rise faster. Once it reaches the ignition point, the tire burns.
2. Frequent sudden braking
When a truck is traveling at high speed, the body mass is large, and the inertial brake will bring greater friction to the brake drum. As an iron product, the heat conduction will be conducted to the entire wheel hub. Frequent braking will generate more heat, which is in contact with the wheel. The toe and mouth area will be damaged by high temperature.
In order to hurry up and accelerate frequently, can the temperature of the steel ring be not high after emergency braking? The temperature of the steel rims was high and the tires ignited the car.
3. The steel rim expired
Tire rims have a "fatigue period". According to industry insiders, the fatigue period of brand rims is about 3 years, and that of non-brand rims is only about one and a half years. If the rims enter the fatigue period, tire eating is prone to occur. , Grinding toe mouth and other problems.
In addition, if there is a problem with the brake components of the car, it will also lead to burned toe. For example, the brake spring cannot be restored, the brake drum is poorly radiated, and the deformation of the wheel hub will cause the burned toe to cause spontaneous combustion of the tire.
