Abstract

The invention concerns a vehicle tyre, comprising two sidewalls, the beads including a seat and an outer edge designed to be urged in contact with an adapted rim, a reinforcing structure, at least one of said beads comprising: a substantially circumferential wire structure, divided into two zones; a zone anchoring the reinforcing structure in said tread, comprising an arrangement of circumferential wires arranged substantially adjacent to a portion of the reinforcing structure and comprising at least two stacks distributed on either side of the reinforcing structure, a binding mixture arranged between the circumferential wires and the reinforcing structure; a clamping zone, radially inside relative to the anchoring zone, comprising an arrangement of substantially elastic circumferential wires distributed in a rubber mixture.
