What are the causes of abnormal tire wear?
1 Answers
Here are the specific causes and solutions for abnormal tire wear: 1. Premature wear in the central part of the tire. Overinflation of the tire not only affects the tire's shock absorption performance but also causes excessive tire deformation. Measure and adjust the tire pressure, and rotate the tires regularly. Note that the rotation methods for radial tires and conventional bias-ply tires are different. 2. Excessive wear on both sides of the tire. Insufficient tire pressure or prolonged overloading increases the contact area between the tire and the ground, leading to premature wear on both sides. Measure the tire pressure and adjust it to the specified value. Limit the load during vehicle use to prevent overloading. 3. Excessive wear on one side of the tire. This is caused by incorrect wheel camber. Repair or replace components on the axle and suspension, and adjust the wheel camber to resolve the issue. 4. Sawtooth-shaped wear on the tire tread. Improper front wheel alignment or issues with the front suspension system, such as loose ball joints, can cause the normally rolling wheel to slide or experience constantly changing alignment during driving, resulting in sawtooth-shaped wear. Adjust the front wheel alignment and inspect the front suspension system and ball joints, making adjustments or replacements as necessary. 5. Patchy wear on the tire. Severe localized wear, appearing as bald spots, is due to poor tire balance. When an unbalanced wheel rotates at high speed, certain areas bear excessive force, accelerating wear and causing steering vibration, which degrades handling. If slight vehicle vibration is noticed at a specific speed during driving, immediately balance the wheels to prevent patchy wear.
