What effect does improper alignment have on tire wear patterns?

Improper alignment can lead to feather-edge wear across the tread of the tire. This occurs when the tires are not perpendicular to the road and not parallel to each other, causing the tire to wear unevenly. In cases of misalignment, one side of the tread may experience more contact with the road than the other, leading to the edges of the tire tread developing a feathered appearance. This pattern is often characterized by one side being more worn than the other, and the transition between the worn and unworn areas can feel rough or “feathery” to the touch.

Feather-edge wear serves as a clear indicator of alignment issues that require correction. Addressing these alignment problems is essential, as this type of wear can reduce the lifespan of the tires and compromise vehicle handling and safety. This understanding of the relationship between alignment and tire wear is crucial for effective vehicle maintenance, ensuring that tires wear evenly and perform optimally.
