Tire comprising a layer of circumferential reinforcing elements

Tire with a radial carcass reinforcement 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 of rubber compound being placed between at least the ends of said at least two working crown layers, a second layer of polymer compound being in contact with at least one working crown layer and in contact with the carcass reinforcement, said second layer of polymer compound extending axially as far as at least the axial end of the tread, said tread radially capping the crown reinforcement and being connected to two beads by two sidewalls, the crown reinforcement comprising at least one layer of circumferential metal reinforcing elements, wherein the elastic modulus under tension at 10% elongation of the first layer of rubber compound is less than 8 MPa wherein the maximum value of tan(δ), denoted tan(δ)max, of the first layer of rubber compound is less than 0.100, and wherein the complex dynamic shear modulus, measured at 10% and 60° C. on the return cycle, of said second layer of polymer compound is greater than 1.35 MPa,

• wherein the tire comprises an additional layer of polymer compound axially in contact with the second layer of polymer compound radially between the carcass reinforcement and the radially innermost layer of reinforcing elements of the crown reinforcement, and
• wherein the complex dynamic shear modulus, measured at 10% and 60° C. on the return cycle, of said additional layer of polymer compound is greater than 1.35 MPa.
