Abstract
Tire comprising a crown reinforcement formed of at least two working crown layers each formed of reinforcing elements inserted between two skim layers of rubber compound. First layer S of polymer compound is in contact with a working crown layer and the carcass reinforcement. The crown reinforcement comprises a layer of circumferential reinforcing elements. The elastic modulus under tension at 10% elongation of a skim layer of a working crown layer is less than 8.5 MPa, the maximum value of tan(δ) of the skim layer of a working crown layer is <0.100. First layer S comprises a filled elastomer blend having a macro dispersion coefficient Z≥65 and a maximum tan(δ) value <0.100 and its complex dynamic shear modulus G*, measured at 10% and 60° C. on the return cycle is >1.35 MPa.
