What Causes Uneven Tire Wear on Small Cars?

[DelZoey]

The causes of uneven tire wear on small cars are as follows: 1. Incorrect wheel alignment, resulting in the four tires not being aligned in the required horizontal and vertical lines. The wheels on the same side experience uneven wear during driving, as the front or rear wheels do not travel straight, causing the vehicle to self-correct. This leads to abnormal friction and accelerated wear on specific parts of a tire. 2. Inaccurate toe adjustment can also cause uneven tire wear. Toe refers to the slight inward tilt of the front wheels, similar to pigeon-toed alignment, which is the optimal angle for high-speed stability. All vehicles have a toe angle, and if this angle is not properly adjusted, it can result in uneven wear, similar to the first point. 3. An uneven or deformed chassis can also lead to uneven tire wear. For example, some accident-damaged vehicles experience uneven wear due to chassis or body deformation.
