A tyre includes a tread with at most 30 channels distributed substantially evenly circumferentially about the tyre. Each channel is arranged so that, beyond a predetermined wear threshold, the channel satisfies the following conditions: (A) the channel opens into a tread pattern element of the tyre, and (B) the channel includes a mouth opening radially to outside of the tyre and is delimited by at least two edge corners that come into contact with a ground surface as the edge corners pass through a contact patch in which the tyre is in contact with the ground surface, in which a circumferential distance separating the edge corners from one another is greater than or equal to 2 mm, and preferably is greater than or equal to 4 mm. Before the predetermined wear threshold is reached, at least one of the conditions (A) and (B) is not met.
