The invention relates to a tyre including a crown reinforcement made up of at least two working crown plies (41, 43) of reinforcement elements and at least one ply (42) of circumferential reinforcement elements, a ply C of rubber mixture being arranged between the ends of the working crown plies. According to the invention, the tread has at least one longitudinal cut-out (8) and at least one transverse cut-out (10), the depth of said at least one longitudinal cut-out and at least one transverse cut-out, measured on a new tyre, being no less than 40 % of the thickness of the tread, the ratio of the width measured at the bottom of said longitudinal cut-outs to the width measured on the surface of the tread of said longitudinal cut-outs being strictly greater than 1.2, the ratio of the width measured at the bottom of said at least transverse one cut-out to the width measured on the surface of the tread on a new tyre of said at least one transverse cut-out being no lower than 1, the distance d between the axially narrowest end of the working ply and the working ply separated from the axially narrowest working ply by the ply C of rubber mixture being such that 1.1o < d < 2.2o, o being the diameter of the reinforcement elements of said at least one ply of circumferential reinforcement elements, and in a meridian plane, the thickness of the ply C of rubber mixture being substantially constant across the axial width between the axially inner end of the ply C and the end of the axially narrowest working ply.
