What is the main cause of severe wear on the inner side of tires?

[Spencer]

The main cause of severe wear on the inner side of tires could be related to wheel alignment, and over-inflation of tires can also lead to inner side wear. More related information is as follows: 1. Wheel alignment issues: Generally related to four factors: front wheel toe-in, camber angle, kingpin inclination angle, and caster angle. 2. Tire pressure issues: Excessive pressure in a tire can accelerate wear on the center of the tread, while insufficient pressure can cause the tire to bow inward, accelerating wear on the outer side of the tread. Additionally, differing pressures in left and right tires can cause the tire with lower pressure to wear more. 3. Regular tire rotation: Ensures even tire wear. Perform wheel alignment every 5,000 to 10,000 kilometers to avoid abnormal severe tire wear. Tires installed on the same axle should not be of different models or have significant differences in wear.
