Patent ID: 7252128

Claim:
A tire P comprising a radial carcass reinforcement radially surmounted by a crown reinforcement composed of at least two working crown plies formed of metallic reinforcement elements crossed from one ply to the next and forming, with the circumferential direction, angles of between 10 and 35°, and by at least one additional reinforcement, formed of circumferentially oriented metallic reinforcement elements, wherein the additional reinforcement is formed of at least two layers of metallic elements of a compacted diameter at most equal to 0.6 mm, wherein the length per turn of the reinforcement elements of the additional reinforcement is, in the plane of each layer, greater by 0 to 3% than the laying length of said elements, wherein the reinforcement elements of the additional reinforcement undulate in the plane of each layer, the wavelength of the undulations being between 20 and 100 mm and wherein the additional reinforcement is positioned radially between the two working plies.
