A tread (12) for a tire (10) which has a tread surface intended to contact a road surface during running. The tread (12) has at least one cavity opening onto the tread surface when new, called external cavity (14), which has length L, width W and central plane P. The external cavity (14) has bottom (16) and at least two opposite lateral walls (18a, 18b) extending from bottom (16) and a mechanism (20) for ejecting stones during running, which has two protuberances (22a, 22b) from bottom (16) of external cavity, which are disposed at least partially opposite one another at a distance d. Each protuberance (22a, 22b) is inclined respectively from a lateral wall (18a, 18b) of the external cavity (14) towards the central plane P.
