<p>Tyre comprising a crown framework formed from at least two working layers each formed of reinforcement elements inserted between two calendering layers of rubber mixture, a first layer S of polymer mixture being in contact with at least one working layer and the carcass framework, and the crown framework comprising at least one layer of circumferential reinforcement elements. The modulus of elasticity under tension at 10% elongation of layer C is greater than 9 MPa, the maximum value of tan(5), denoted tan(5) max, of said layer C is less than 0.100, said first layer S consists of a filled elastomer mixture having a macro dispersion score Z greater than or equal to 65 and a maximum value of tan(5), denoted tan(5)max, less than 0.100 and the complex dynamic shear modulus G* thereof, measured at 10% and 60°C on the return cycle, is greater than 1.35 MPa.</p> |
