What is the proper procedure for repairing a tire?
Any tire found to be under inflated should be removed from the wheel and inspected thoroughly on both the outside and inside surfaces. Puncture repairs should be done using a patch on the inside tire surface and solid material inserted into the hole to prevent moisture damage to steel tire cord. Puncture repairs should only be done in the tread area of the tire that is reinforced by the steel belts. Sidewall damage is usually too severe to repair. Tire repair should be done by experienced and trained technicians only.
