Abstract:
1. A tire, comprising at least one reinforcement structure 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 base of the bead and a radial position of the 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 the structure, arranged in the bead, towards the sidewall, at least one arrangement of main cord windings along a substantially circumferential path being arranged substantially adjacent to the 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, wherein a number of main cord windings arranged on the axially inner side relative to said at least one reinforcement structure is greater than zero, and a number of main cord windings arranged on the axially outer side relative to said at least one reinforcement structure is equal to or greater than zero, the arrangement of the cord windings of the at least one arrangement being such that the number of main cord windings arranged on the axially inner side relative to the at least one structure is greater than the number of main cord windings arranged on the axially outer side relative to the at least one structure, all of the main cord windings having a radial position not extending beyond the axial bearing zone.
