Heavy Goods Vehicle Tire with Complex Tread Pattern

A tire () for a heavy-duty vehicle having a tread () with at least one complex circumferential cut (), consisting of an alternation of external cavities (), which open onto the tread surface (), and of internal cavities (), which are hidden inside the tread (), and aims to reduce its sensitivity to irregular wear. At least one complex circumferential cut () has only one of its two walls () substantially planar, such that the intersection of said wall () with the tread surface () forms a line () the amplitude of axial variation (A) of which is at most equal to 2% of the axial width (L) of the tread ().
