The invention relates to a tyre comprising a crown ply formed by at least two working crown layers of reinforcing elements, cross-laid from one layer to the next and forming angles of between 10° and 45° with the circumferential direction. A first layer S of polymer blend extends axially at least to the axial end of the tread and is in contact with at least one working layer and in contact with the carcass ply. 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. |
