TIRE HAVING IMPROVED WEAR PROPERTIES The invention relates to a tire including a crown reinforcement formed of at least two working crown layers (41, 43) of reinforcing elements and at least one layer (42) of circumferential reinforcing elements, a rubber mixture layer C being placed between the ends of the working crown layers. In accordance with the invention, the tread has at least one diagonally oriented cut (7), the depth, measured on a new tire, of said at least one diagonally oriented cut being greater than or equal to 40% of the thickness of the tread, the ratio of the width measured at the bottom of said at least one diagonally oriented cut to the width measured on the surface of the tread of said at least one diagonally oriented cut being greater than 1.2, the distance d between the end of the axially narrowest working layer and the working layer separated from the axially narrowest working layer by the rubber mixture layer C being such that l.lo < d < 2.2o, 0 being the diameter of the reinforcing elements of said at least one layer of circumferential reinforcing elements, and in a meridian plane, the thickness of the rubber mixture layer C being substantially constant over the axial width between the axially inner end of the layer C and the end of the axially narrowest working layer.
