ABSTRACT:
The invention comprises a method and apparatus for repairing a ruptured sidewall in a truck tire which eliminates bulging. The method includes the inventive step of removing the sidewall reinforcement pad from the interior of the repair area after curing the tire. The apparatus used to perform this operation comprises a sidewall reinforcement pad having a metal layer disposed between two layers of rubber. In one preferred embodiment, the metal layer is comprised of longitudinally disposed metal cords. The metal cords give additional strength to the section repair patch and prevent bulging of the ruptured repair area during the curing process.
