Patent ID: 8096335

Claim:
A heavy vehicle tire, comprising a radial carcass reinforcement, radially surmounted by a working crown reinforcement, made up of at least four continuous working crown plies formed of reinforcing elements which, from one ply to the next, cross one another making the angles α 1 , α 2 , α 3 , α 4 of between 5 and 30° with the circumferential direction, the working crown reinforcement being radially surmounted by a protective reinforcement made up of at least one ply of elastic metal reinforcing elements that make an angle γ of between 10 and 30° with the circumferential direction, the end of the said protective ply being axially on the outside at the ends of the working plies, wherein the working crown reinforcement is supplemented on each side of the circumferential mid-plane by a single working half-ply the reinforcing elements of which make an angle β greater than 30° with the circumferential direction, wherein the working half-ply is radially on the inside of and adjacent to the radially outermost continuous working ply, wherein its axially outer end is axially on the outside of the ends of the continuous working plies, and wherein the reinforcing elements of the working half-ply, the reinforcing elements of the radially outermost continuous working ply and the reinforcing elements of the protective ply the end of which is axially on the outside of the ends of the working plies are oriented in the same direction.
