A tire, designed to carry heavy loads, having a radial carcass reinforcement formed of at least one ply of inelastic reinforcing elements and anchored in each bead to a bead wire so as to form a turn-up whose end is a radial distance HRNC away from the base of the bead, each bead being reinforced by at least two additional reinforcement armatures, at least one first armature being formed of radial reinforcement elements and at least one second armature being formed of elements that make with the circumferential direction an angle alpha such that 0°<=alpha<=45°, the first reinforcement armature being formed of radial elements and being wrapped around the bead wire outside the carcass reinforcement while the second armature is not wrapped around the said bead wire. |
