A heavy-duty vehicle tire tread to improve resistance to chunking of the oblique sipes opening into the external cavities thereof and having at least one substantially longitudinal cut (3) with at least one external cavity (6) open onto the tread surface (2) along an open section (7) having a closed contour (8). Each cavity (6) is connected to two substantially longitudinal sipes (91) and to an oblique sipe (92) having a mean plot (M2) intersecting the contour (8) at a connection point (I). The mean plot (M2) forms an angle (A1, A2) strictly greater than 90° with at at least two straight lines (T1, T2) tangential to the contour (8) respectively at two points (I1, I2) of the contour (8) that are positioned on either side of the mean plot (M2) and at a curvilinear distance (d1, d2) from the connection point (1) at most equal to 2 mm.
