Abstract: A process for the manufacture of a tire the beads of which are without anchoring bead wires and are reinforced by complexes of layers of reinforcement elements of low angle, around which complexes the radial carcass reinforcement is anchored by winding, said process being characterized in that each complex is produced independently of the carcass reinforcement blank, the manufacture of said complex including using at least one raw blank of reinforcement elements which are oriented at a higher angle than the angle to be obtained in the vulcanized state, subjecting said ply to pre-extension before formation of a two-layer sleeve, the pitch, angle and width characteristics of which are obtained by pantograph effect upon a second extension.

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
