What are the causes of tire wear?
2 Answers
Tire wear can be attributed to the following 5 reasons: 1. Inaccurate wheel alignment, causing misalignment of the same-side wheels during operation or front and rear wheels not being aligned: Inaccurate wheel alignment leads to tire wear when the same-side wheels are misaligned during operation or when front and rear wheels are not aligned. Vehicle calibration results in abnormal increase in friction at a specific part of the tire and accelerated wear; 2. Inaccurate toe adjustment can also cause tire wear: The front wheels slightly tilt inward at an angle similar to pigeon toes, which is the optimal angle for high-speed stable driving. All vehicles have their own toe angle. If the angle is not adjusted properly, it can also lead to tire wear; 3. Steering gear failure may also cause tire wear and deviation; 4. Uneven and deformed chassis can also lead to tire wear: The cause of tire wear is deformation of the chassis body; 5. Mixing tires of different specifications and significant differences in tire pressure among tires: Mixing tires of different specifications and significant differences in tire pressure among tires can both lead to tire wear.
I've encountered many cases of tire wear issues, and I need to analyze it from the alignment perspective. Incorrect four-wheel alignment data is the real culprit behind tire wear! Especially when the toe and camber angles are off, it's like a person walking with their toes pointed inward or outward—how can the tires not wear unevenly? Issues with chassis components such as loose steering linkage ball joints or worn-out lower control arm bushings can immediately throw the alignment off. At our repair shop, we often see vehicles that have been driving on rough roads for a long time without suspension checks. When chassis parts wear out and aren't replaced in time, the tires gradually wear into a sawtooth pattern. I recommend getting a professional four-wheel alignment check every 20,000 kilometers, especially before fitting new tires—alignment data must be adjusted first.
