Abstract:
A covered cord is formed by covering a cord with a resin material, and a covered bead is formed by welding or adhering together the resin material of the covered cord whilst shaping into a bead shape, such that resin material fills between the cord. The covered bead is placed in contact with a jig disposed inside a cavity of a tire mold for molding a tire frame member, the covered bead is fixed inside the mold, and the tire frame member is molded containing the covered bead in a tire bead portion by pouring molten resin material into the cavity.
