Patent ID: 7299843

Claim:
A tire comprising a crown extended by two respective sidewalls and two respective beads, a carcass structure anchored in each side of the tire in said beads, said crown comprising: at least one reinforcing ply having parallel reinforcements oriented at an angle α relative to the circumferential direction ranging between 10 and 45 degrees; a first crown reinforcement having cords substantially oriented in the circumferential direction and being high elastic modulus at 4% strain organic fiber cords; and a second crown reinforcement having cords substantially oriented in the circumferential direction and having a ratio τ of the tensile strength at a strain of 2.5% and a temperature of 180° C. to the tensile strength at a strain of 1% at 80° C. inferior to 1.5, the second crown reinforcement further being low elastic modulus at 4% strain cords, wherein neither the first nor the second crown reinforcements are edge plies.
