Patent ID: 7210512

Claim:
A tire comprising at least one carcass-type reinforcement structure anchored on either side of the tire in a bead, the base of which is intended to be mounted on a rim seat, each bead being extended radially towards the outside by a sidewall, the sidewalls radially towards the outside joining a tread, the carcass-type reinforcement structure extending circumferentially from the bead towards said sidewall, a crown reinforcement, each of the beads furthermore comprising an anchoring zone permitting the reinforcement structure to be held and comprising a plurality of circumferential cord windings cooperating with the adjacent portion of the reinforcement structure by an anchoring rubber mix, said cord windings of the anchoring zone being arranged so as to form at least one cord stack extending between a first winding and a last winding in which the distance “d” between the cord of said first winding and its substantially adjacent portion of the carcass-type reinforcement structure and the distance “d” between the cord of said last winding and its substantially adjacent portion of the carcass-type reinforcement structure form a progression from the axial position of each of the windings relative to the carcass-type reinforcement structure, wherein said plurality of circumferential cord windings directly cooperates with the adjacent portion of the carcass-type reinforcement structure, wherein the winding closest to the reinforcement structure is the radially outermost of the progression.
