Patent ID: 7500501

Claim:
A tire comprising a radial carcass reinforcement radially surmounted by a crown reinforcement comprising at least one working reinforcement, wherein the at least one working reinforcement comprises: at least two working crown plies comprised of calendered inextensible metallic reinforcement elements and rubber mix, said at least two working crown plies comprising a radially inner working crown ply having an axial width L 1 and a radially outer working crown ply having an axial width L 2 , the metallic reinforcement elements of said radially inner and outer working crown plies being parallel to each other within each working crown ply and being crossed from one of said at least two working crown plies to the next, forming respective angles α 1 and α 2 of between 10° and 45° with the circumferential direction; a protective ply comprising metallic reinforcement elements and having an axial width L 3 , the protective ply being adjacent to said radially outer working crown ply; and a layer P of cohesive rubber mixes arranged between at least the ends of the at least two working crown plies, wherein L 2 <L 3 <L 1 , wherein a radial distance between the radially inner and outer working crown plies, separated by the layer P, is equal to d, at an end of the radially outer working crown ply, and wherein an end of the protective ply is separated radially from the radially inner working crown ply by the layer P at a distance d′ , such that d≦d′<d+ 4φ 2 where φ 2 is the diameter of the metallic reinforcement elements of said radially outer working crown ply.
