How to Solve the Issue of Uneven Rear Tire Wear on Volkswagen CC?

[SanRichard]

Tires are consumable parts, but they should not wear out quickly and typically wear evenly under normal conditions. If a tire shows uneven wear on one side, it is often due to incorrect toe adjustment, which can be corrected by adjusting the length of the steering tie rod. If the vehicle also pulls to one side, it indicates that the wheel camber angle is also misaligned, requiring adjustment of the suspension angles on a four-wheel alignment machine. Main causes of uneven tire wear: 1. Front wheel (steering wheel) uneven wear: Incorrect alignment adjustment when driving straight, where the tires are not in a straight position when the steering wheel returns to center or the steering gear is at zero position. Incorrect toe adjustment; for radial tires, the toe value should be ±0mm, and for bias-ply tires, ±3mm. 2. Rear wheel (drive wheel) uneven wear: Cumulative tolerances leading to unequal wheelbase on both sides of the frame. 3. Common causes for both front and rear wheel uneven wear: Quality issues with the tire or wheel itself, causing severe ovality, resulting in uneven contact force with the ground during rolling and accelerated wear.
