The invention relates to a tyre including a crown reinforcement formed of at least two working crown plies (41, 43) of reinforcement elements and at least one ply (42) of circumferential reinforcement elements. According to the invention, the tread has at least one cut-out with oblique orientation (7), the depth of said at least one cut-out with oblique orientation, measured on a new tyre, being no lower than 40% of the thickness of the tread, the ratio of the width of said at least one cut-out with oblique orientation, measured at the bottom, to the width of said at least one cut-out with oblique orientation, measured at the surface of the tread, being greater than 1.2, the modulus of elasticity under tension at 10% elongation of at least one liner layer of at least one working crown ply being greater than 9 MPa, and the maximum value of tan(8), noted as tan(8) max, of said at least one liner layer of at least one working crown ply being lower than 0.100. |
