    Abstract: A tire for a vehicle wheel, comprising two sidewalls joined by a crown zone provided on its radially outer portion with a circumferential tread, a bead arranged at the radially inner portion of each of the sidewalls, each bead comprising a seat and an outer flange which are intended to come into contact with the rim. The bead seat has a generatrix, the axially inner end of which lies on a circle of diameter greater than the diameter of the circle on which the axially outer end is located. A carcass-type reinforcement structure extends substantially radially from each of the beads, along the sidewalls, towards the crown zone, such bead being reinforced by a substantially radial arrangement of circumferential cords arranged in stacks. A portion of the carcass-type reinforcement structure is arranged in the immediate vicinity of at least one portion of a stack, and the space between these portions is generally occupied by a rubber mix of high elasticity modulus.

    Abstract: The invention concerns a tire whose crown contains a ply of circumferentially oriented cords. That ply is so arranged that in sensitive zones, as, for example, at the side ends of the adjacent crown reinforcing ply, the laying pitch of the circumferentially oriented cords is markedly increased. That considerably lessens the risk of damage to the circumferentially oriented cords in those zones.

    Abstract: The anchoring of the carcass reinforcing elements 1 is assured by circumferential cables 2, with the interposition of a connecting rubber composition 3. The circumferential cable 2 is arranged in several turns forming one or more helices. These circumferential cables have an operational elongation rate Af=Ae+Ap of more than 4%. This operational elongation rate does not include the specific elongation As of the “cable” effect. The maximum stress Rm of the cable 2 is preferably more than 2000 MPa. The cables have undergone a heat treatment which has, in combination, the features of being a recovery annealing treatment and which is carried out directly on cable comprising wires previously separately covered by an adherent coating.
