ABSTRACT:
A tire includes a carcass-type reinforcement structure anchored on either side of the tire in a bead. Each of the beads includes an anchoring zone having a plurality of circumferential cord windings cooperating with the adjacent portion of the reinforcement structure. The cord windings are arranged to form a cord stack in which the distance between the cord of a radially innermost winding and an adjacent portion of the reinforcement structure differs from the distance between the cord of the radially outermost winding and an adjacent portion of the reinforcement structure, wherein the stack is non-parallel to the reinforcement.
