  • Tires


    Regular tire care and maintenance is the key to the well being of your tires and your safety. Perform the following actions at least once a month:

    • Measure your tires pressure when they are cold, using a good quality tire gauge (you can’t tell whether a tire is under inflated just by looking at it).
    • Inspect the tread for signs of uneven wear.
    • Inspect the tire for embedded stones, glass and other foreign objects that could work their way into the tire and cause a leak.
    • Check the remaining tread depth – tires are manufactured with a “wear bar” that tells you when there is less than 1.6 mm (2/32 inch) of tread depth remaining and when you see this wear bar, the tire must be replaced.

    Cupped Tire Wear: Produced by an unbalanced tire condition, faulty wheel bearings, or weak shock absorbers.

    Scrubbed Tire Wear: Usually caused by excessively loose, worn, or bent tie rod ends, idler arms, or steering linkage components.

    Uneven Tire Wear: A result of incorrect alignment or worn ball joints and bushings.

    Variable Tire Wear: Caused by a combination of misalignment, weak shocks, worn control arm bushings, and excessively loose ball joints.
