Tire comprising a tread (3), with a tread surface contacting the road surface, a shoulder region (5) partially delimiting the tread (3), and a plurality of complex cutouts (6) extending through the tread (3) and through the shoulder region (5). Each complex cutout (6) comprises a sipe (7) that leads onto the tread surface and a channel (8) that extends the sipe (7) into the depth of the tread and leads onto a surface (9) of the shoulder region (5). Channel (8) of sipe (7) has a main part (11) extending through tread (3) and a widened part (12) extending through shoulder region (5) from the main part of the channel to surface (9) of shoulder region (5).
