Tire manufacturing method using jig to fix covered bead inside tire mold

A tire manufacturing method comprising:

• forming a covered cord by covering a cord with resin material;
• forming a covered bead 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;
• putting the covered bead in contact with a main jig and an auxiliary jig both disposed inside a cavity of a tire mold for molding a tire frame member, and fixing the covered bead inside the mold;
• and
• molding a tire frame member containing the covered bead in a tire bead portion by pouring molten resin material into the cavity,
• wherein the covered bead contacts the main jig on a tire inner side,
• wherein putting the covered bead in contact with the main jig disposed inside the cavity of the tire mold comprises placing a portion of the covered bead in a recess portion of the main jig, the recess portion having the same shape as the external shape of the portion of the covered bead in the recess portion, such that the covered bead is in a retained state in which movement towards the tire inside direction is restricted and movement in the tire radial direction is restricted but movement towards the tire outside direction is not restricted,
• wherein the auxiliary jig contacts the covered bead on a tire outer side opposite to the tire inner side, and
• wherein fixing the covered bead inside the mold comprises pinning the covered bead between the main jig and the auxiliary jig.
