ABSTRACT:
A tire includes a radial carcass reinforcement surmounted radially by a crown reinforcement including a working reinforcement having two working crown plies of calendered inextensible metallic reinforcement elements and rubber mix. The reinforcement elements are parallel to each other within each ply and are crossed from one ply to the next, forming with the circumferential direction respective angles α1and α2of between 10° and 45°. The working crown plies have respective axial widths L1and L2. The tire also includes a protective ply of metallic reinforcement elements with an axial width L3such that L2<L3, L2being the width of the working ply adjacent to the protective ply. A layer of cohesive rubber mix GB is arranged radially internal to the working reinforcement such that the axially outer end of the layer GB is at a distance from the equatorial plane greater than L1/2.
