Which alignment angle is most likely to cause tire wear?

Toe is the alignment angle that is most likely to cause tire wear. It refers to the angle at which the tires point inward or outward when viewed from above. If the toes are misaligned—meaning they either point too much inward (toe-in) or outward (toe-out)—this can lead to uneven tire wear. For instance, excessive toe-in can cause the tires to wear on the inside edges, while excessive toe-out can result in wear on the outer edges. Proper toe alignment is crucial for maintaining even tire wear and ensuring that the vehicle drives straight without dragging, which ultimately contributes to overall vehicle stability and performance.

Caster and camber also affect vehicle handling and tire wear but are generally less influential in creating uneven tire wear in the same manner as toe. Steering Axis Inclination (SAI) mainly contributes to the steering characteristics of the vehicle rather than directly affecting tire wear.
