The invention relates to a tyre comprising a tread layer (3), said tread layer comprising a running surface suitable for coming into contact with the roadway, a shoulder area (5) partly delimiting the tread layer (3), and a plurality of complex cutouts (6) extending into the tread layer (3) and into the shoulder area (5). Each complex cutout (6) comprises an incision (7) opening out on the running surface and a channel (8) extending the incision (7) into the depth of the tread layer and opening out on a surface (9) of the shoulder area (5). The channel (8) of the incision (7) comprises a main portion (11) extending into the tread layer (3) and a wider portion (12) extending into the shoulder area (5) from the main portion of the channel up to the surface (9) of the shoulder area (5). Viewed in cross-section, the wider portion (12) makes an output angle [Delta] of less than 90 degrees with the surface (9) of the shoulder area (5). 本发明涉及种轮胎，其包括胎面层(3)，所述胎面层包括适合于与道路接触的行驶表面，部分地限定胎面层(3)的胎肩区域(5)，以及延伸通过胎面层(3)并延伸至胎肩区域
