TIRE HAVING BEAD PORTION FOR IMPROVING TRANSVERSE RIGIDITY AND DURABILITY

A tire having a bead portion for improving transverse rigidity and durability may comprise: a bead bundle positioned on the bead portion of the tire; a bead filler having a lower end portion coupled to the upper surface portion of the bead bundle, the bead filler being disposed to extend from the bead bundle to a side wall; a carcass coupled to the inner surface of the side wall of the tire and disposed to extend such that the inner surface of the bead filler and the lower portion of the bead bundle are surrounded; an inner liner coupled to the inner surface of the carcass and disposed to extend to the bottom surface portion of the carcass; and rim cushion rubber coupled to extend from the lower inner surface of the inner liner to the bottom surface portion of the carcass, thereby surrounding one edge of the carcass.
