MAJOR VEHICLE FACTORS WHICH AFFECT TIRE LIFE:

ALIGNMENT

Alignment refers not only to the various angles of the steer axle geometry, but also to the tracking of all axles on a vehicle, including the trailer. The dual purpose of proper alignment is to minimize tire wear and to maximize predictable vehicle handling and driver control. Toe misalignment is the number one cause of steer tire irregular wear, followed by rear axle skew (parallelism or thrust). One of the challenges of meeting this goal is that alignments are typically performed on a static, unloaded vehicle sitting on a level floor
