The present invention relates to a low-noise tyre (1) for a heavy goods vehicle, the tyre comprising a tread (2) that has at least two complex circumferential cuts (41, 42) arranged next to one another and separated from one another by a circumferential row of raised elements (5). Each complex circumferential cut (41, 42) comprises alternating external cavities (61, 62), distributed according to a circumferential pitch (Pc), and internal cavities (71, 72). The raised elements (5) are separated in pairs by incisions (8) that each have two ends (I1, I2) and are distributed according to a circumferential pitch (Pi). According to the invention, the circumferential distance (Di) between the two respective ends (I1, I2) of each incision (8) is equal to the circumferential pitch (Pi) of the incisions (8) and the circumferential pitch (Pc) of the external cavities (61, 62) is equal to the circumferential pitch (Pi) of the incisions (8).
