TIRE INSPECTION Any tire that is determined or suspected to be run-flat, should be inspected thoroughly prior to returning to service. Look for wrinkling, discoloration, cracking, and/or degradation of the inner liner. Any breach to the inner liner can result in the introduction of moisture to the casing and subsequent corrosion. If any signs of run-flat exist to the inner liner, the tire should be made unusable and scrapped. Abrasion marks on the sidewall due to road contact and/or creases in the sidewall are another indicator of run-flat. Feel for soft spots in the sidewall flex area. Using an indirect light source helps identify sidewall irregularities by producing shadows at the ripples and bulges. Look for protruding wire filaments indicating broken sidewall cords. All patches should be inspected for lifting, cracks, splits, and general condition.
