How to Adjust Excessive Wear on the Outer Edge of Front Tires?
2 Answers
Excessive wear on the outer edge of front tires is caused by incorrect toe-in or camber angles, which can be resolved by performing a wheel alignment. Below is supplementary information about wheel alignment: 1. Definition: Wheel alignment involves adjusting the geometric angles of the tires, steering, and suspension components to ensure tight contact between the tires and the ground. 2. Benefits of wheel alignment: Enhances driving safety, reduces tire wear, keeps the steering wheel straight when driving straight, maintains straight-line driving, allows the steering wheel to automatically return to center after turning, improves driving control, reduces fuel consumption, and decreases wear on suspension components. 3. When wheel alignment is needed: After replacing steering system components, when there is uneven wear on one side of the front or rear tires, after replacing or adjusting the suspension system, wheel alignment should be performed.
Last time my car also had the issue of the front tires wearing on the outer edges, to the point where one side was completely worn flat. I guessed it was due to incorrect wheel alignment. At that time, I felt the steering wheel pulling slightly outward while driving, so I quickly went to a nearby repair shop. The mechanic first checked the tire pressure and said it was too low, which would accelerate wear. Then, they tested it on the alignment machine and indeed found that the camber angle was too large, causing the wheels to tilt outward. They adjusted the suspension control arms and steering knuckles to correct the angles, costing less than 200 yuan in total. They also recommended checking the alignment every 5,000 kilometers. After the adjustment, the car became much more stable and no longer had tire wear issues. The key is not to delay—severe tire wear can easily lead to blowouts, especially on highways, which is very dangerous. I think I should develop the habit of checking the tire pressure monthly, keeping it between 2.3-2.5 bar, and avoiding hitting curbs randomly—these steps can help prevent problems.
