Maintenance

To maximize tire performance, inspect them for signs of improper inflation and uneven wear, which may indicate a need for balancing, rotation or front suspension alignment. Tires should also be checked frequently for cuts, stone bruises, abrasions, blisters, and for objects that may have become imbedded in the tread. More frequent inspections are recommended when rapid or extreme temperature changes occur, or where road surfaces are rough or occasionally littered with debris.

As a further visible check of tire condition, tread wear indicators are molded into the bottom of the tread grooves. The tire should be replaced when these indicator bands become visible.

To clean tires, use a mild soap and water solution only and rinse thoroughly with clear water. Do not use any caustic solutions or abrasive materials. Do not use steel wool, wire brushes, gasoline, paint thinner or similar materials having a mineral oil base. These materials are harmful to the tires and will eventually discolor the whitewalls and raised letters.
