Abstract: An annular side wall rubber is injection molded, a forming mold is mold released while retaining the side wall rubber in an unvulcanized state, and a side surface of the side wall rubber is exposed annularly. Further, a lower mold of the forming mold is moved close to a carcass body in which a center portion is evaginated to an outer side in a diametrical direction, on a forming drum, and the side surface of the side wall rubber is attached to a side portion of the carcass body. Thereafter, the side wall rubber is released from the forming mold by moving the lower mold away from the carcass body.
