What Causes Severe Wear on the Inner Side of Front Wheels?
2 Answers
Severe wear on the inner side of a car's front wheels is caused by incorrect wheel alignment or long-term lack of tire rotation. Among these, improper front wheel camber angle and toe-in can lead to uneven wear on the front wheels. When such wear occurs, it is essential to promptly perform wheel balancing or four-wheel alignment and inspect the relevant wheel hubs and bearings. Severe wear on the inner side of front wheels can manifest in the following situations: 1. Wear on the center of the tire tread. 2. Wear on both shoulders of the tire tread. 3. Wear on the inner or outer side of the tire tread. 4. Sawtooth-like wear on the tire tread. 5. Wave-like or disc-like wear on the tire tread. 6. Localized wear on the tire tread.
I've been driving for over twenty years, and every time I see the inner side of the front tires worn out, it's really annoying. It's mainly due to incorrect wheel alignment, especially when the camber angle is too negative, which forces the tires to grind inward. The situation gets worse if you frequently make sharp turns or drive on bumpy roads. It could also be caused by low or fluctuating tire pressure. When the pressure is insufficient, the tire deforms, increasing the contact area of the inner side with the ground, leading to faster wear. Additionally, issues with suspension components, like bent control arms or loose tie rods, can cause the tires to tilt inward. I recommend checking the tire pressure regularly—once a month is enough—and getting a wheel alignment every 10,000 kilometers to avoid spending a lot on new tires. Worn-out tires are not only dangerous but also affect handling, making the car prone to shaking during high-speed turns.
