Low-noise tire for a heavy goods vehicle

A tire for a heavy-duty vehicle, comprising a tread, intended to come into contact with the ground via a tread surface, and comprising at least two juxtaposed complex circumferential cuts which, with a circumferential direction (XX′) of the tire, form a mean angle at most equal to 30°, and which are separated from one another by a single circumferential row of raised elements,

• each complex circumferential cut comprising an alternation of external cavities, which open onto the tread surface and are distributed at a circumferential pitch (Pc), and of internal cavities, which are hidden inside the tread when the tread is new, two consecutive respectively external cavities and internal cavities being connected to one another,
• each circumferential row of raised elements, which is delimited by two juxtaposed complex circumferential cuts, comprising raised elements, pairs of which are separated by sipes, distributed at a circumferential pitch (Pi) and each sipe having two ends (I1, I2) opening into an external cavity of each of the two juxtaposed complex circumferential cuts,
• wherein the circumferential distance (Di) between the respective two ends (I1, I2) of any each sipe in each circumferential row of raised elements is equal to the circumferential pitch (Pi) of the sipes (8) and wherein the circumferential pitch (Pc) of the external cavities of each of the two juxtaposed complex circumferential cuts is equal to the circumferential pitch (Pi) of the sipes.
