What is a common cause of uneven tire wear on the front tires?

Uneven tire wear on the front tires is commonly caused by incorrect toe alignment. Toe alignment refers to the angle at which the tires point relative to the centerline of the vehicle. When the toe is not set correctly, it can cause the tires to drag, leading to increased wear on one edge of the tire. This uneven wear can manifest as scalloping or cupping on the tread, particularly noticeable on the inner or outer edges, depending on whether the toe is toe-in or toe-out.

Maintaining proper toe alignment is crucial for the longevity of the tires and overall vehicle performance, as it ensures that tires roll straight and do not create unnecessary friction. Regular alignment checks and adjustments help minimize uneven tire wear and promote safer driving conditions.
