What Causes Uneven Tire Wear on Car Tires?

[BlakelyAnn]

There are several reasons for uneven tire wear on car tires: 1. Incorrect wheel alignment, which causes uneven wear when the two wheels on the same side or the front and rear wheels are misaligned during operation. The vehicle's self-correction leads to abnormal increases in friction and accelerated wear on a specific part of the tire. 2. Inaccurate toe adjustment can also cause uneven wear. This means the front wheels are slightly tilted inward at an angle similar to a pigeon-toed stance, which is the optimal angle for high-speed stability. Every car has its own toe angle, and if this angle is improperly adjusted, it can result in uneven wear. 3. Steering gear failure may also lead to uneven wear or pulling to one side. 4. An uneven or deformed chassis can cause tire wear. For example, in some accident-damaged vehicles, the cause of uneven wear is chassis or body deformation. 5. Mixing tires of different specifications or having significantly different tire pressures can also lead to uneven wear.
