The invention relates to a tyre comprising a crown ply formed by at least two working layers each formed by reinforcing elements inserted between two rubber blend skim coats, a first layer S of polymer blend being in contact with at least one working layer and in contact with the carcass ply, and the crown ply comprising at least one layer of circumferential reinforcing elements. The tensile modulus of elasticity at 10% elongation of at least one skim coat of the working layers is less than 8.5 MPa, the maximum value of tan(δ), denoted tan(δ)max, of the first skim coat being less than 0.100. The first layer S is formed by a loaded elastomer blend having a macro dispersion rating Z greater than or equal to 65 and a maximum value of tan(δ), denoted tan(δ)max, less than 0.100, and the complex dynamic shear modulus G* of said first layer S, measured at 10% and 60°C on the return cycle, is greater than 1.35 MPa. |
