What Causes Inner Wear on Rear Tires of Sedans?

[MaciFitz]

The reasons for inner wear on rear tires of sedans: 1. Unstable vehicle center of gravity. Some models have rear-mounted engines, or other factors such as armored bodies cause the center of gravity to shift backward, leading to severe wear on the rear tires; 2. Poor four-wheel alignment, causing uneven tire wear and abnormal abrasion; 3. The vehicle's self-correction causes abnormal friction on a specific part of a tire, accelerating wear; 4. Inaccurate toe-in adjustment. The front wheels are slightly tilted inward at an angle resembling pigeon toes, which is the angle for stable high-speed driving. All vehicles have their own toe-in angle, and improper adjustment of this angle can also cause tire wear.
