Abstract: The tire has a single layer of cushion compound between the cords of the carcass reinforcement that are furthest radially outward in the crown and the cords of the belting that are furthest radially inward in the crown. The single layer of cushion compound may have either a high modulus of elasticity of between 7 and 25 MPa for high crown rigidity or a low modulus of elasticity of less that 6 MPa for reduced hysteresis energy loss.

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 A.sub.f =A.sub.e +A.sub.p of more than 4%. This operational elongation rate does not include the specific elongation A.sub.s of the "cable" effect. The maximum stress R.sub.m 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.
