PURPOSE:To stick tire pieces to a rim surely by a method in which the tire pieces are molded by the outer mold heated at the temperature where green rubber is vulcan ized in a short time and the core mold regulated at the temperature where green rubber is not almost vulcanized in short time, and after a rim has been nipped by the surfaces molded with the core mold of the tire pieces, the tire is molded and vulcanized. CONSTITUTION:In the manufacture of a wheel, tire pieces 130 are molded by the outer molds 11, 12 heated at the temperature where green rubber is vulcanized in a short time and the core mold 20 regulated at the temperature where green rubber is not almost vulcanized in a short time. A rim 107 is nipped with the surfaces 123' molded by the core mold 20 of the tire pieces 130, and then the tire pieces 130 are connected and are integrally molded and vulcanized. Since the surface 123' is formed with the core mold 20 regulated at the temperature where green rubber is not vulcan ized in a short time, when the tire pieces 130 are molded integrally with the rim 107, the tire pieces 130 are surely stuck to the rim 107. Since the outer molds 11, 12 are heated at the temperature where green rubber is vulcanized in a short time, the outer surface of the tire has been already vulcanized in the tire piece-molding process, and the vulcanizing time when the tire pieces 130 are integrally molded, is shortened. |
