What Causes Feathering Wear on Tires?

[Jeff]

Feathering wear on the tire tread is primarily caused by improper toe adjustment. Excessive toe-in forces the tire to slide outward, causing the tread's contact surface to drag inward on the road, resulting in toe-in wear. The tread exhibits a distinct feather-like pattern, which can be identified by running a finger from the inside to the outside of the tire tread. More details are as follows: 1. On the other hand, excessive toe-out pulls the tire inward, causing the tread's contact surface to drag outward on the road, leading to toe-out wear. This phenomenon can even create a noticeable left-right wobbling sensation while driving, which is quite dangerous. 2. The symptom of feathering wear on the tire tread is manifested in several main grooves, where the edges become extremely thin over time, resembling feather-like strands.
