Summary: | The present invention relates to a tyre (1) for a heavy goods vehicle comprising a tread (2) having at least one complex circumferential cut (41, 42) consisting of an alternation of external cavities (61, 62) that open onto the tread surface (3), and of internal cavities (71, 72) that are hidden inside the tread (2), and aims to improve the sensitivity of the tread to uneven wear. According to the invention, at least one complex circumferential cut (61, 62) has just one of its two walls (81, 82) substantially planar so that the intersection of the wall (81, 82) with the tread surface (3) forms a line (811, 821) of which the amplitude (A) of the axial variation is at most equal to 2% of the axial width (L) of the tread (3). |
