Under normal circumstances, heavy truck tires with normal wear simply roll in driving, and the ground resistance of tires is mainly the rolling friction. The rapid tire wear-out is mainly due to the sliding friction between the whole tread, a pattern, or a point with the ground.

Judging the direction of friction at each point is the key to accurately judge the driving state of heavy truck tires, which has also become a faster and better way to solve problems in practical technology in addition to equipment detection.

Here we summarize several phenomena and the causes of the serious wear-out problem of heavy truck tyres for your reference, so that you can suit the remedy to the case whenever the problems occur.

1. Bidirectional wear in the same position

Phenomenon: Heavy truck tyres are worn flat in the same position around the tyres.

Causes: The brake is locked, resulting in that the tyres are dragged and slide on the ground; check the brake mechanical parts fault and brake gas circuit fault.

2. The accessory wheel is worn irregularly

Phenomena: At the same position of two heavy truck tires, one position is normal and the other is irregularly worn.

Causes: The patterns of the two tire are different; the diameter of the two tires is different; there is a problem in the balance beam or arm sleeve clearance; the steel ring is seriously deformed; the pressure of the two tyres is different.

3. Channel-shaped wear

Phenomenon: Both sides of the tread groove of heavy truck tyres are worn.

Causes: The heat dissipation in tire pattern groove is poor; the steel ring is not properly matched with the tyre or installed; the steel ring is deformed; the heavy truck often turns fast.

4. Fish-scale-shaped wear

Phenomenon: It looks that the whole tread is cut by a knife.

Causes: The road conditions are poor, such as gravel pavements and truck weighing platforms; the steering angle is too large; The steel plate pin bushing is seriously worn; the strength of the steel plate reduces; the front and rear vertical walls are out of proportion; the quality of the tyres is poor; the traction plate is too far back (oversteer).

5. The heel-to-toe shaped wear

Phenomenon: This kind of wear appears in the heavy truck tyres with drive axle block patterns and deep tread rubber. The deeper the tread rubber is, the more likely this kind of abnormal wear is to occur.

Causes: In the early use, the grounding elasticity of a single pattern is large, and deep patterns are not conducive to heat dissipation; the air pressure is too high; the damping is failed.
