Tyre comprising a crown framework formed from at least two working crown layers having unequal axial widths, one layer C of a rubber mixture being disposed between at least the ends of said working layers, a second 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 radially arranged between two working layers. The distance between the end of the axially narrowest working layer and the working layer separated from same by layer C is such that 1.1∅< d < 2.2∅, ∅ being the diameter of the reinforcement elements of the circumferential layer; in a meridian plane, the thickness of layer C is essentially constant and the complex dynamic shear modulus G* of said second layer S, measured at 10% and 60 °C on the return cycle, is greater than 1.35 MPa. |
