Abstract
An improved tire patch is disclosed herein for use either singularly or jointly with a tire repair plug for sealing a puncture of a vehicle tire. The improved repair patch includes a thick seal portion made of a soft resilient air impervious closed cell elastomer fully encased in a thin outer covering of the same material. The seal portion has parallel upper and lower faces and an aperture in the center portion thereof. A thin cover portion is bonded to the upper face of the thick portion and subtends the aperture thereof. The repair patch, when adhesively applied to the inner surface of a punctured tire with the aperture thereof positioned directly opposite the puncture, improves the durability of the repair, allows the joint use of a tire repair plug and avoids exposure of the repair patch to damage from the ends of broken steel reinforcing wires of steel belted radial ply tires.
