Causes of 5 Abnormal Tire Wear You Need to Know
(Baonghean.vn) - When using a vehicle for a period of time, the tires will gradually wear out, affecting the overall performance. In addition, signs of abnormal wear can occur due to many different causes. Therefore, regularly checking the wear of the tires not only helps you determine when to replace them, but also can maintain the tires properly for long-term use.
1. Even wear on the tire surface
 |
A tire that is worn evenly across the surface is caused by a problem with the wheel's suspension system. Worn or damaged bearings, springs, shock absorbers or axles will affect the up and down movements of the wheel. It creates a secondary force on the wheel.This side force acts repeatedly on the entire tire surface, causing tire surface wear.
2. Uneven wear over the entire tire surface
 |
Uneven wear in one or more areas of the tire surface is usually caused by incorrect wheel alignment settings. Unbalanced wheels rotating at high speeds will release a constant side force on the road surface and centrifugal force also increases the possibility of wheel imbalance.As a result, normal wear and tear is not caused.The cause of this could be an incorrectly set up suspension, which causes uneven wear on the tire surface.
3.Wear in the middle of the tire surface
 |
If the middle of the tire surface is worn more than other areas, it shows that this area is subject to more friction.
NThe cause may be due to too high tire pressure. When the tire is over-inflated, the center of the tire surface protrudes more than the two sides of the tire, so under normal conditions the center of the tire will be subjected to more frictional force.
If the vehicle is driven in this condition for a long time, the center of the tire will wear more. When the vehicle is running at high speed, a large centrifugal force will be generated, pressing on the tire tread in the center of the tire surface; the result will be tire wear.
4. Heavy wear on one side of the tire
 |
If the tire is worn on only one side, it means that only one side of the tire is subjected to a much greater frictional force. The cause is that the cam angle is not set properly.
If this angle is not set correctly, the contact will not be optimal. This will result in wear marks on the inside or outside of the tire sidewall.
Another cause of one-sided tire wear is the manufacturer's incorrect placement of the steel cord in the center of the tire. However, due to the strict standards of manufacturers, this error rarely occurs.
5. Sidewall wear
 |
The sidewalls of the tire wear more than the center of the tire surface due to low tire pressure. Prolonged low tire pressure will reduce the contact between the tire and the road surface, so the two sides of the tire will have to bear a higher load.
Another possible cause of increased sidewall wear is high speed cornering. But this always happens on multiple wheels at the same time.
