Many conditions, including the following list, can cause irregular or premature tire wear:

    • Incorrect inflation pressure
    • Lack of regular rotation
    • Driving habits
    • Improper tire and wheel alignment

If you reset tire and wheel alignment due to a tire wear condition, always rest the toe as close to 0 degrees as the specification allows.

Rotate the tires if you notice any of the following conditions:

    • Front and rear tire wear is unequal
    • The tread of any tire wear is uneven
    • Left and right front tire wear is unequal

Test the tire and wheel alignment if you notice any of the following conditions:

    • The left and the right front tire wear is unequal
    • The tread of any front tire wear is uneven
    • The front tire treads have a scuffed appearance with feather edges on one side of the tread ribs or blocks
