What are the reasons for uneven tire wear on a car?
2 Answers
The reasons for uneven tire wear on a car are: 1. Inaccurate four-wheel alignment; 2. Incorrect toe adjustment; 3. Steering gear malfunction or pulling to one side; 4. Uneven or deformed chassis frame; 5. Mixing tires of different specifications with significant pressure differences among them. Uneven tire wear refers to the abnormal accelerated wear on the inner or outer side of one or more tires. Methods to prevent uneven tire wear include: 1. Adjusting tire pressure and always maintaining normal tire pressure; 2. Paying attention to tire maintenance and rotation, performing tire rotation every 8,000 to 10,000 kilometers to ensure even wear and extend tire life; 3. Checking whether wheel hub screws are loose; 4. Avoiding overloading and ensuring balanced tire load distribution.
My car used to frequently experience uneven tire wear on one side, which was quite annoying. Later, a check at the repair shop revealed that the main issue was incorrect wheel alignment, commonly known as misaligned four-wheel positioning. This causes uneven tire pressure distribution, leading to severe wear on one side. Problems with the suspension system, such as worn shock absorbers or deformed control arms, can also cause abnormal tire wear. Of course, improper tire pressure is a common cause—both overinflation and underinflation can accelerate wear. I've tried checking the tire pressure gauge myself to avoid this issue. Additionally, driving habits play a role; frequent hard braking or driving too fast on rough roads can cause tires to wear out prematurely. To sum up, ignoring these problems increases driving risks. I recommend regular professional inspections—simple adjustments like realigning the wheels can solve most issues.
