A tire comprising a tread. This tread comprises at least one elongate block delimited by at least one lateral wall (5) and a contact face (7). The lateral wall (5) makes a non-zero angle with a transverse direction and the contact face contacts a road surface. The tire comprises at least one channel (19) extending through the elongate block and leading onto the lateral wall (5) of this elongate block. The tire also comprises a sipe extending from the channel towards the contact face, this sipe leading onto the lateral wall of the elongate block in a lateral wall outlet region. The lateral wall of the elongate block is inclined with respect to a radial direction (Z), at least in the lateral wall outlet region of the sipe, at an angle θ of between 20 degrees and 60 degrees with respect to this radial direction (Z).
