ABSTRACT:
A method of inspecting a tire for defects by applying to an interior surface of a tire a coating of material which accentuates defects when influenced by predetermined electromagnetic wavelengths, road-running the tire to thereby create tread wear, buffing the exterior tread surface of the tire, and applying predetermined electromagnetic wavelengths to the exterior of the buffed tread surface whereby coating material which has migrated through a defect in the tire to the exterior is accentuated and thereby readily detected. Preferably the coating material fluoresces or brightens when subjected to ultraviolet light. The coating material is preferably part of an admixture composed of the ultraviolet light accentuating coating material and a tire sealant which seals punctures, nail holes and the like when the same migrates through the tire.
