Abstract
Tire comprising a crown reinforcement formed of at least two working crown layers of reinforcing elements, crossed from one layer to the other making with the circumferential direction angles comprised between 10° and 45°. A first layer S of polymer compound is in contact with at least one working crown layer and in contact with the carcass reinforcement, the first layer S of polymer compound extending axially as far as at least the axial end of the tread, the first layer S of compound polymer compound is made up of a filled elastomer blend having a macro dispersion coefficient Z greater than or equal to 65 and a maximum tan(δ) value, denoted tan(δ)max, less than 0.100 and its complex dynamic shear modulus G*, measured at 10% and 60° C. on the return cycle is greater than 1.35 MPa.
