If the toe-in is too great, the tread will most likely show:

When toe-in is set too great, it causes the front tires to point inward excessively as they roll down the road. This improper alignment leads to a specific wear pattern known as feathering. In this scenario, the edges of the tire tread develop irregularities that create a serrated appearance, commonly described as feathered. This condition occurs when the inside edge of the tire wears more than the outside edge due to the angle at which the tire meets the road.

This type of wear pattern can compromise vehicle stability and steering response. Recognizing feathering can be an indicator for technicians to check the toe alignment and adjust it to the manufacturer’s specifications, ensuring that tire wear is uniform, which ultimately enhances vehicle safety and tire lifespan.
