What are the causes of abnormal tire wear?
2 Answers
Here are the specific causes and solutions for abnormal tire wear: Premature wear in the center of the tire: Over-inflation of the tire, which not only affects the tire's shock absorption performance but also causes excessive deformation of the tire. Measure and adjust the tire pressure, and rotate the tires regularly. Note that the rotation methods for radial tires and ordinary bias tires are different. Excessive wear on both sides of the tire: Insufficient tire inflation or prolonged overloading, which increases the contact area between the tire and the ground, leading to early wear on both sides. Measure the tire pressure and adjust it to the specified value. Limit the load during vehicle use to prevent overloading. Excessive wear on one side of the tire: Caused by incorrect wheel camber angle. Repair or replace components on the axle and suspension, and adjust the wheel camber angle to resolve the issue. Sawtooth wear on the tire tread: Improper front wheel alignment or abnormal positioning of the front suspension system, loose ball joints, etc., causing the normally rolling wheel to experience sliding of the support frame or constantly changing wheel alignment during driving, resulting in sawtooth wear. Adjust the front wheel alignment and inspect the front suspension system and ball joints, making adjustments or replacements as necessary. Patchy wear on the tire: Severe localized wear in certain areas of the tire, indicating poor tire balance. When an unbalanced wheel rotates at high speed, certain areas bear significant force, accelerating wear, accompanied by steering vibration, which worsens handling. If slight shaking is noticed at a specific speed while driving, the wheels should be balanced immediately to prevent patchy wear.
The tires are wearing unevenly. After driving for half my life, I've summarized the reasons. The primary issue is incorrect tire pressure: too high and the center of the tread wears out quickly; too low and the edges wear out first. Misaligned wheels are also a problem, such as when the car pulls to one side, causing excessive wear on one side of the tire. Aggressive driving habits—hard braking and rapid acceleration—accelerate tire wear. Worn suspension components, like failing shock absorbers, cause excessive bouncing and abnormal tire wear. Poor road conditions, like driving on bumpy surfaces, also wear tires out faster. I always recommend checking tire pressure monthly, getting a wheel alignment every six months, and choosing the right tire model for your vehicle when replacing tires—safety first.
