Tire having a crown, a crown reinforcement, sidewalls and beads, a carcass reinforcement passing into the sidewalls and anchored in the beads. The anchoring is accomplished, in at least one bead, by a circumferential alignment of an anchoring reinforcing member oriented circumferentially and cooperating with a rubber composition. The anchoring reinforcing member is a metal cable having a construction M+N with an inner layer Cof M wires of diameter dwound together in a helix at a pitch p, this layer Cbeing surrounded by an outer layer Cof N wires of diameter dwound together in a helix at a pitch p. This anchoring cable satisfies (d, d, pand pbeing expressed in mm): 2≦M≦4, M+3≦N ≦M+7, 0.25 <d<0.40, 0.25 <d<0.40, 3.5 <p<7<p<14.
