The invention relates to a tyre that comprises a crown reinforcement made up of two working crown plies, in which the inner-liner plies comprise carbon black, and a ply of circumferential reinforcement elements. According to the invention, the reinforcement elements of the working crown plies are metal cables having a diameter smaller than 1.3 mm, at least one wire of each metal cable of at least one working crown ply is of at least UHT grade, the modulus of elasticity of the inner-liner plies of the working crown plies is lower than 8 MPa, and the inner-liner plies of the working crown plies have a volume resistivity ρ such that log(ρ) is higher than 8. |
