Abstract:
A cylindrical body is formed by mounting a carcass to the outer periphery of a film formed of a thermoplastic resin or a thermoplastic resin elastomer composition. A molded body is formed by fitting bead rings on opposite width direction ends of the cylindrical body, and the molded body is sucked on a transfer mold's inner periphery. After a rigid inner mold is inserted into the molded body, suction stops and the molded body is transferred to the inner mold's outer periphery. Opposite carcass ends in a width direction are turned up on the inner mold, while other tire members are stacked on the molded body's outer periphery to mold a green tire. The tire and inner mold are placed in disposed inside a heated curing mold and the film is inflated to cure the tire and bond the film to the inner peripheral tire surface to form an inner layer.
