Why is the outer side of the front tire severely worn?
1 Answers
It is related to inaccurate four-wheel alignment data. This requires replacing the worn tires and then performing a four-wheel alignment. Some models experience this issue because they only have independent front suspension, while others have independent suspension that cannot be adjusted, requiring professional inspection and repair. Other wear conditions are as follows: 1. Early wear on the central part of the tire (tread crown): The main reason is over-inflation. Properly increasing tire pressure can reduce rolling resistance and save fuel. However, excessive inflation not only affects the tire's shock absorption performance but also causes excessive deformation, reducing the contact area with the ground. As a result, normal wear is concentrated on the central part of the tread, leading to early wear. 2. Excessive wear on both sides of the tire (shoulders): The main reasons are under-inflation or long-term overload driving. When tire pressure is low or the load is heavy, the contact area between the tire and the ground increases, causing both sides of the tire to engage with the ground and leading to early wear. If tire pressure is 20% above or below the rated value, mileage loss can range from 20% to 25%. 3. Excessive wear on one side of the tire: The main reason is inaccurate front-wheel alignment. When the camber angle of the front wheels is too large, the outer side of the tire experiences early wear. Conversely, if the camber angle is too small or absent, the inner side of the tire will show early wear.
