Abstract

A method for the restoration of radial cord vehicular tires having damaged cords. A portion of the inner surface of the tire casing is removed over a region including at least the damaged area to a depth sufficient to remove all damaged radial cords. This removal region includes up to, and across, both bead portions of the casing. A patch unit having a conforming outline to that of the trough created by the removal is inserted into the trough and is bonded therein. This patch unit extends in the trough across the bead portions. The patch unit contains reinforcing cords to replace those that are removed. Preferably, the body of the patch unit is formed of uncured rubber which is cured in place in the casing so as to become permanently bonded to the casing. Cosmetic repair of the external surface can be accomplished by removing damaged material and thereafter filling the region, preferably with uncured rubber that is cured in place. Tires restored according to this method have performance equivalent to undamaged tires.
