A tire comprising a crown reinforcement formed of at least two working crown layers each one 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 the layer C is greater than 9 MPa, the maximum value of tan(δ), denoted tan(δ)max, of the layer C 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.
