Abstract
A tire with a radial carcass having a breaker structure that comprises two radially overlapped layers of metallic fabric reinforced by cords transversely disposed with respect to the circumferential direction of the tire. These cords are crossed over each other and, on each axial extremity of the two layers, there is positioned at least a rubberized fabric strip reinforced by metallic cords of high elongation (HE) or very high elongation (VHE) in combination with Hybrid textile cords (Aramide/Polyamide) disposed in the circumferential direction and having, in the vulcanized tire, a modulus of elongation of non-increasing value passing from the axially outermost cord to the axially innermost one. This strip is suitably constructed by the coupling of cords of (axially from the outside to the inside) HE-VHE (High Elongation--Very High Elongation), HE-Hybrid (High Elongation--Aramide/Polyamide) and VHE-Hybrid.
