Causes of serious wear and tear of ordinary semi-trailer tires

According to investigations, abnormal tire wear (commonly known as “tire eating”) is common in the current production of medium-sized semi-trailers. Generally, it is more obvious when driving 2x104km, and the most obvious is driving 5x104km. Worn tires account for about 30% of the total number of semi-trailers. On the basis of investigation and analysis, several measures to improve the abnormal wear of medium-sized semi-trailers are put forward.

1.Early wear of the central part of the tire.

The main reason: the tire inflation is too large, which not only affects the damping performance of the tire, but also causes the tire to deform too much.

2. Excessive wear on both sides of the tire.

The main reason: insufficient tire inflation or long-term overload driving, which makes the tire and the ground contact surface large, causing both sides of the tire to contact the ground and form early wear.

3. Excessive wear on one side of the tire.

Main reason: It is caused by the wrong camber angle of the wheel.

4. Jagged wear appears on the tire tread.

The main reason: improper adjustment of the front wheel alignment, abnormal position of the front suspension system, loose ball head, etc., which cause the sliding of the support frame of the normally rolling wheels or the continuous change of the wheel positioning during driving, resulting in jagged wear of the tires.

5. Excessive wear of individual tires.

The main reason: It is caused by the malfunction of the individual wheel suspension system, the bending of the support frame or the unbalance of the individual wheels.

6.. Alopecia areata appears on the tires.

The main reason: the severe wear of alopecia areata in individual parts of the tire is due to the poor balance of the tire. When the unbalanced wheel rotates at a high speed, the individual parts are subjected to a lot of force, and the wear is accelerated correspondingly, and the steering shakes, which makes the maneuverability worse.

Driving skills are closely related to tire wear. The correct operation of the driver plays a key role in the service life of tires. If you start too fast, frequently emergency braking or carelessly choosing the road, improper driving operations will cause damage to the tires. Therefore, we should develop good driving habits. The wear rate of tires is directly related to the road conditions, so we should try our best to improve driving. Road conditions, reduce the impact of road conditions on tire wear, and at the same time pay attention to cleaning up the ground of the storage yard to avoid or reduce the damage to the tires caused by rocks.

Overloading of tires will increase the bending deformation on both sides of the sidewall, increase the fatigue of the carcass, accelerate the wear, and even cause the tire to burst. Overloading will greatly shorten the life of the tire. You should learn to use the tire correctly.

The tire is a ring-shaped elastic rubber product that is assembled on various vehicles or machinery and rolls on the ground. Usually installed on a metal rim, it can support the car body, cushion the external impact, achieve contact with the road and ensure the driving performance of the vehicle. Tires are often used under complex and harsh conditions. They are subjected to various deformations, loads, forces, and high and low temperature effects during driving. Therefore, they must have high load-bearing performance, traction performance, and cushioning performance. At the same time, it also requires high wear resistance and flex resistance, as well as low rolling resistance and heat build-up. Half of the world's rubber consumption is used for tire production, which shows the ability of tires to consume rubber.
