ABSTRACT:
A method and closure are provided for sealing and repairing a puncture of a tire. The closure is a resilient plug of a rubber-like material stiffer and more durable than prior closures having a generally cylindrical shank portion and an adjoining circular head portion. The periphery of the shank portion has a labyrinth of closely spaced sealing rings and grooves therebetween. When the shank portion is forcibly engaged with a puncture, the sealing rings individually radially compress and locally conform to the size and shape of the puncture thereby providing multiple sealing members with the puncture. Additional sealing is provided by an auxiliary sealing ring on the head portion of the closure which is adhesively bonded to the inner surface of the tire, adjacent to the puncture. Tool attaching means are provided on the closure for forcibly engaging the closure with the puncture. The method of repair includes the steps of selectively matching the size of the aforedescribed closure with a puncture, applying an adhesive to the periphery a body and lower head surface of the closure, affixing an assembly tool to the closure, forcibly inserting the closure into the puncture and trimming excess material from one end of the closure.
