Patent ID: 8037912

Claim:
A tire, comprising at least one reinforcement structure of the carcass type anchored on either side of the tire in a bead, the base of which bead is intended to be mounted on a rim seat of a standard rim for the tire, each bead being extended radially towards the outside by a sidewall, and comprising an axial bearing zone extending substantially between the bead base and a radial position of said bead substantially corresponding to the position of the radially outer edge of a hook of the rim, the sidewalls radially towards the outside joining a tread, on the circumference of the tire the at least one reinforcement structure extending from an end portion of said structure, arranged in the bead, towards said sidewall, at least one arrangement of main cord windings along a substantially circumferential path being arranged substantially adjacent to said end portion so as to form an anchoring zone, the main cord windings anchoring the at least one reinforcement structure in the bead and/or clamping the bead, each main cord winding arranged on the axially inner side relative to said structure having a Young's modulus E I and a surface S I and each main cord winding arranged on the axially outer side relative to said structure having a Young's modulus E e and a surface S e , the arrangement of the main cord windings of said at least one arrangement being such that Σ(E I ×S I ) int >Σ(E e ×S e ) ext , all of said main cord windings having a radial position not extending beyond said axial bearing zone.
