Patent ID: 7461678

Claim:
A tire comprising: a radial carcass reinforcement radially surmounted by a crown reinforcement comprising a working reinforcement, the working reinforcement comprising: at least two working crown plies of calendered inextensible metallic reinforcement elements and rubber mix, the 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 the radially inner and outer working crown plies being parallel to each other within each working crown ply and being crossed from one working crown ply to the next, the metallic reinforcement elements of the radially inner and outer crown plies 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 the radially outer working crown ply; and a layer of cohesive rubber mix GB which is disposed radially inward of the working reinforcement, wherein an axially outer end of said layer of cohesive rubber mix GB is at a distance from an equatorial plane of the tire greater than L 1 /2, wherein L 2 is less than L 3 , and wherein L 2 is less than L 1 , and at least in each shoulder, an additional ply of reinforcement elements, which are parallel to each other in the additional ply and forming with the circumferential direction an angle of between 70° and 110°, wherein an axially inner edge of said additional ply is radially adjacent to at least one edge of one of the plies of the crown reinforcement, and an axially outer edge of said additional ply is radially internal to both the axially outer end of the layer of cohesive rubber mix GB and an edge of the ply to which the additional ply is adjacent.
