Below are details about tire patching methods: 1. Patch Repair Method: The tire is separated from the rim, and the damaged area inside the tire is sanded down to ensure better adhesion of the glue. After cleaning the sanded debris, a special tire repair adhesive is applied to the damaged area and its surroundings.
