Abstract: A machine for applying tire paint and tire sealant to recapped tire sidewalls and interiors, respectively. The machine includes a pair of tire paint applicator pads which are carried by a frame and carriage capable of reciprocal motion in three different directions to bring the applicator pads into selective engagement with tire sidewalls. The machine also includes spray nozzles carried by an associated frame and carriage for bringing the nozzles into a position to direct tire sealant into the interior of an associated recapped tire.

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.
