TREAD LAYER FOR A TYRE COMPRISING CHANNELS

摘要

The invention relates to a tyre, comprising a tread layer. Said tread layer comprises at least one elongate block. The elongate block is delimited by at least one side wall (5) and a contact face (7). The side wall (5) forms a non-zero angle with a transverse direction and the contact face is intended to come into contact with a roadway. The tyre comprises at least one channel (19) extending into the elongate block and opening out on the side wall (5) of said elongate block. The tyre also comprises an incision extending from the channel towards the contact face, said incision opening out on the side wall of the elongate block at an output zone of the side wall. The side wall of the elongate block is inclined with respect to a radial direction (Z), at least in the output zone of the side wall of the incision, at an angle θ of between 20 degrees and 60 degrees with respect to said radial direction (Z).
