Patent ID: 10399385

Abstract:
Tire comprising a crown reinforcement formed of at least two working crown layers each being formed of reinforcing elements inserted between two skim layers of rubber compound, a first layer S of polymer compound being in contact with at least one working crown layer and in contact with the carcass reinforcement and the crown reinforcement comprising at least one layer of circumferential reinforcing elements. The elastic modulus under tension at 10% elongation of at least one skim layer of at least one working crown layer is greater than 9 MPa, the maximum value of tan(δ), denoted tan(δ)max, of the at least one skim layer of at least one working crown layer is less than 0.100 and the complex dynamic shear modulus G*, measured at 10% and 60° C. on the return cycle, of the first layer S of polymer compound is greater than 1.35 MPa.
