ABSTRACT:
A mold for vulcanizing tires includes an annular bead molding ring. The bead molding ring has a toe edge, a bead flat surface and a toe portion. The toe portion comprises a support which projects radially outwardly from the bead flat surface. The toe portion may comprise a plurality of circumferentially spaced and axially extending supports. The amount of radial projection of each support may progressively decrease or taper at axially spaced locations increasingly spaced from the toe edge of the bead molding ring.
