Abstract

L'invention concerne un pneumatique à armature de carcasse radiale, constituée d'une unique couche d'éléments de renforcement ancrée dans chacun des bourrelets par retournement autour d'une tringle. Selon l'invention, le retournement de la couche d'armature de carcasse et la partie principale de la couche d'armature de carcasse sont couplés, le retournement de la couche d'armature de carcasse et la partie principale de la couche d'armature de carcasse sont les seules couches d'éléments de renforcement dont l'allongement à rupture est inférieur à 6 % présentes dans le flanc et l'agencement et le choix des mélanges polymériques de la zone du bourrelet du pneumatique favorisent les performances d'endurance quelles que soient les conditions de roulage après un vieillissement sur une longue période en étant gonflés avec des teneurs en agents oxydants élevées.
