First: high temperature

Second : bad position of axles

The tire is a rubber product. The curing temperature is about 150 C in factory manufacture and 120 C in maintenance. It is recommended that the tire temperature should not exceed 75 C in normal use.

The brake drum and wheel hub can reach up to 500 degrees! Over 200 degrees high temperature. What kind of rubber tires can't stand.

For ordinary tyres, it has been vulcanized for two times more than 150 degrees.

A lot of car owners find a tire problem, the first reaction is the quality of the tire, and then go to replace the tire, but you have not thought that the tire problem is not necessarily a quality problem, it is likely to be caused by the brake drum.

After the brake drum burns red, the temperature will pass directly to the tire steel ring, the tire mouth will be damaged, the temperature of the hub will rise, there is always a problem of tire bursting in the process of driving.

Why is there a phenomenon of burning bead toe ? Overload is the main factor. At this stage, the phenomenon of Heavy Truck Overload in China is still repeatedly prohibited, overload on the one hand will make the tire has been in a high load state, will also aggravate the friction between the tire and the steel ring, resulting in bead toe burning disease.

Different tire wear phenomena and reasons

1,The wear of both ends is due to inadequate tire pressure or overload.

2,Tire wear is caused by excessive tire pressure.

3,The cause of tire wear is due to the excessive front or camber angle and the bending of steering knuckle arms.

4,The cause of tire wear is too small for toe in or camber.

5,The feathery wear from the outside to the inside of the tire is caused by the excessive front bundle, the bending of the steering knuckle arm, and the left and right lateral tension.

6,The cause of feather wear from inside to outside is due to excessive rear beam and bending of steering knuckle arm. The length of the bar is different.

7, Ripple-shaped tire feeding on the crown of the tire is due to the large dynamic unbalance of the wheel, the gap between the wheel bearings and the large wheel alignment deviation.

8, Disk-shaped tire feeding on the crown of the tire. The reasons for such dish-shaped wear at one or more places on the tread are large dynamic unbalance of the wheel, clearance of the wheel bearings, large wheel alignment deviation, clearance of the ball pin, clearance of the horizontal tie rod, bending of the axle, eccentricity of the brake drum, and sudden braking, starting and turning.

9, the reason why the crown is eaten in the pit is that the wheel is not well balanced.

10,Sawtooth wear, block pattern tire will produce this kind of wear, the main reasons are wheel bearing clearance, front bundle is not good, negative back tilt angle, wheel dynamic imbalance, turning radius (turning around the front wheel angle) is not good, and so on.

Solutions to tire wear

1. adjust tire pressure

You know that tire pressure is too high or too low, which will cause uneven tire wear. When the tire pressure is too low, the tire will bend inward, which will easily lead to serious wear and tear on the edge of the tire; and when the tire pressure is too high, the wear and tear in the middle of the tire tread will appear accelerated phenomenon. Therefore, we should pay more attention to whether the tire pressure is in a normal state, generally according to the car's tire pressure inflation, deflation can be.

2. do wheel balancing regularly.

Due to the manufacturing process or some external factors, the quality of each part of the wheel may be uneven. So when the automobile wheel rotates at high speed, it will form a dynamic unbalance state. In order to avoid this phenomenon or eliminate this phenomenon, it is necessary to make the wheel adjust the balance of each edge part by increasing the counterweight in the dynamic situation, so as to avoid the occurrence of "tire wear".

3. make four rounds regularly.

Four-wheel alignment can increase driving safety, increase the service life of tires, reduce fuel consumption, reduce tire wear (avoid eating tires), reduce the wear of suspension parts and other functions, so it is necessary to regularly go to 4S shop or more professional repair shop to do four-wheel alignment. It is recommended to do it at least once a year or ten thousand kilometers.

4. pay attention to tire maintenance and transposition.

I believe many people have heard that whenever a car travels a certain distance, it has to change the position of the tire. Generally speaking, whenever a vehicle travels 5,000 kilometers, it needs to change the position of the tire. However, how to change the position of the tire? It is better to change the tire diagonally, because it can maintain the tire normally and make the tire wear out. Uniform, thereby prolonging tire life.

5. check whether the hub screws are loose.

Wheel hub bearing loosening, leaf spring riding bolt not tightened according to regulations, suspension loosening and so on will cause the tire to swing left and right in the running, resulting in abnormal tire wear. So in the maintenance of vehicles, carefully check the wheel around the wheel and the hub of the screws, see if there is loose.
