 The main raw materials for tire manufacturing are rubber and skeleton materials (such as nylon cord, steel cord, etc.). When the temperature rises, various materials show different characteristic changes. Nylon cord is different from other materials and shrinks when heated. High temperature can also accelerate the aging process of rubber, so we say that the main cause of tire damage is the high temperature of tire body.

When you find that the tire temperature is too high, you must stop to cool down. Because when the temperature of the tire body enters the high temperature, the physical and mechanical properties of the rubber and the cord will be reduced, the adhesion of the rubber and the cord will be reduced, the thermal aging will be accelerated, and the crown, shoulder and side parts of the tire are prone to void and delamination; Under the impact of external force, it is also easy to cause the tire crown and tire shoulder to burst.

Therefore, users must comply with the Tire Use and Maintenance Regulations during use; At the same time as the first and second level maintenance of vehicles, the first and second level maintenance of tyres should also be carried out.

● Air pressure

Tyres should be inflated according to the specified standards. Too high or too low air pressure will cause early tire damage.

Low air pressure has the following effects:

1. Under low pressure, TEREX spare tire body deformation increases and tire heat rise increases, which is easy to cause tire body delamination, cord breakage and toe opening explosion.

2. The inner tube is damaged due to the high heat rise of the tire.

3. When two tires are installed together, the adjacent tire sides are damaged by mutual extrusion and friction. If the pressure of one tire is too low, the load of the other tire will be increased, and the tire will be damaged early.

4. When the tire is working at low pressure, the outer tire of TEREX spare parts is easy to produce relative displacement on the rim, resulting in the fall off of the tire grinding toe and inner tire valve.

5. Insufficient air pressure will aggravate abnormal tire tread wear and increase fuel consumption. According to the data, if the air pressure is lower than 10% of the standard air pressure, the mileage of the tire will be reduced by about 12%; The air pressure is lower than 25% of the standard air pressure; The mileage of tyres will be reduced by about 30%.

● Load

Overload will shorten the service life of the vehicle parts and tires, cause the tire body deformation to increase, at the same time, increase the contact area with the ground, accelerate the wear of the tire surface, and the tire heats up quickly, causing the tire to be damaged in advance.

The effects of overloading on tyres include:

1. The ply separation between the carcass ply and the ply separation between the tread and the buffer layer finally forms a drum explosion.

2. The tread pattern is cracked.

3. Overload increases the deformation of the matrix, which is easy to cause broken line and toe blasting.

4. When the tire is used with more than the standard load, the deformation part of the tire will expand, the temperature of the tire body will increase, and the service life of the tire will be reduced. Overload of 10% will reduce the service life of the tire by about 20%; Overload will also increase the rolling resistance. Overload of 30% will increase the rolling resistance of the tire by about 45-60%.
