Abstract
Repair materials made of at least unvulcanized rubber are applied on a repair site of a damaged part of a tire, heating pads are applied on surfaces of the repair materials, wood pieces or other stuffing members differing in size are stuffed inside the tire, in a tire circumferential in tire circumferential direction where the repair materials are applied. The tire circumferential is fastened and pressed from surroundings by bands, and the repair site is heated by the heating pads to vulcanize the unvulcanized rubber of the repair materials, to thereby repair the tire. This repair method provides a low-cost tire repair method capable of maintaining the shape of the tire at the time of pressing and vulcanization, in various kinds of tires.

- stuffing a plurality of stuffing members in the tire in a circumferentially restricted part of the tire in which the repair material is deposited;
- fastening the circumferentially restricted part of the tire from outside thereof to apply a pressure thereto;
- and
- heating a repair site including the damaged part by heating the heating pad to vulcanize the unvulcanized rubber of the repair material, wherein
- the repair material is deposited from a tire inside in a part facing the tire inside of the damaged part, and the heating pad is applied on an inside of the repair material;
