Abstract: A tire with radial carcass reinforcement having two beads, the carcass reinforcement extending from one bead to the other, each bead having no anchoring bead wire and being reinforced by an armature including at least two plies (2) and (3) turned up over themselves to form four reinforcement layers (21, 31, 32, 22) axially close to one another, the two axially innermost layers (21, 31) being composed of elements parallel to one another from one layer (21) to the next (31), and the two layers (31, 32) axially at the center of the reinforcement being composed of elements crossed from one layer (31) to the next (32), such that the said elements make with the circumferential direction an angle null such that 0null

Abstract: A tire with a carcass reinforcement ply, anchored within each bead by winding around an annular element, the tensile strength of which is less than the tensile strength of a conventional tire bead wire of the same dimension, and an assembly of at least two textile bead reinforcement layers which are arranged in contact with the annular element, wherein the annular element is metallic, has a tensile strength of between 3 and 5 times the tension imparted to the carcass reinforcement by the recommended inflation pressure, and the elongation at break of which is at least equal to 6%, all the reinforcement layers formed of elements of aromatic polyamide having a tensile strength of between 0.5 and 1 time the tensile strength of the annular element, and the total of the tensile strengths of the annular element and of the assembly of the reinforcement layers being between 6 and 8 times the tension imparted to the carcass reinforcement.
