Final answer:
Proper toe alignment is necessary for even tire wear and extended tire life. When the tires are aligned correctly, the tread surface is parallel to each other and perpendicular to the road surface. This helps prevent uneven wear on the tires.
Step-by-step explanation:
Proper toe refers to the angle at which the tires are pointed in relation to the centerline of the vehicle. To achieve even tire wear and extended tire life, the tires should be aligned so that the tread surface is parallel to each other and perpendicular to the road surface.
For example, if the tires are toed in, meaning they are pointed towards each other, the inner edges of the tires will wear out faster. On the other hand, if the tires are toed out, meaning they are pointed away from each other, the outer edges of the tires will wear out faster.
By ensuring proper toe alignment, you can help maximize the lifespan of your tires and promote even wear across the tread surface.
