The present invention relates to a tyre (1) for a trailer of a heavy duty vehicle and aims to increase its grip performance on snow, without degrading its mechanical strength with respect to scrubbing stresses. According to the invention, the tread (2), having at least one complex circumferential cut (7) in a median portion (4), comprises a first family of transverse cuts, called transverse through-sipes (81), having a thickness (E1) at most equal to 0.8 mm, a depth (P1) at least equal to 20% of the maximum cut depth (H), and being at a distance (D1), with respect to the nearest external cavity (71), at least equal to 7 mm, and/or a second family of transverse cuts, called blind transverse cuts (82), stopping in the vicinity of an external cavity (71), having a thickness (E2) at least equal to 1 mm, a depth (P2) at most equal to 20% of the maximum cut depth (H), and being at a distance (D2), with respect to the external cavity (71), at least equal to 3 mm.
