Abstract
Tire comprising a crown reinforcement formed of two working crown layers having unequal axial widths, layer C of rubber compound between ends of the working crown layers, layer S of polymer compound in contact with at least one working crown layer and in contact with the carcass reinforcement and the crown reinforcement comprising a layer of circumferential reinforcing elements arranged radially between two working crown layers. Distance d between the end of the axially narrowest working layer and the working layer separated from the axially narrowest working layer by the layer C is 1.1ø<d<2.2ø, ø being the diameter of the reinforcing elements of the layer of circumferential reinforcing elements, in a meridian plane. The thickness of layer C is substantially constant and the complex dynamic shear modulus G*, measured at 10% and 60° C. on the return cycle, of layer S is greater than 1.35 MPa.
