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 a zone of axial bearing 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 said structure, arranged in the bead, towards said sidewall, at least in the end portion said at least one structure being axially separated into at least two portions, at least one arrangement of main cord windings along a substantially circumferential path being arranged substantially adjacent to at least one of the portions of said at least one structure 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, the arrangement of the main cord windings of said at least one arrangement being such that the surface density of main cord windings arranged on the axially inner side relative to said at least one structure is greater than the surface density of main cord windings arranged on the axially outer side relative to said at least one structure, all of said main cord windings having a radial position not extending beyond said zone of axial bearing.
