A tire for an aeroplane and, in particular, to the crown of a tire for an aeroplane, having reduced dimensions and mass of the pieces of tread in the event of accidental tire tread separation, without the use of additional devices external to the tire and therefore without penalizing the payload of the aeroplane, having a tread intended to come into contact with the ground via a tread surface, and extending radially between a bottom surface and the tread surface, the tread comprising at least two circumferential ribs adjacent to at least one circumferential groove, each circumferential rib extending radially between the bottom surface and the tread surface, axially between two lateral faces and circumferentially around the entire periphery of the tire, wherein the tread comprises rows of cavities formed in at least one circumferential rib and opening onto the tread surface, the rows of cavities, which are parallel to one another, are inclined with respect to the circumferential direction (XX′) of the tire at an angle (i) at least equal to 45°, and the rows of cavities are distributed circumferentially over at least part of the periphery of the tire with a circumferential spacing (p) at least equal to 0.02 times and at most equal to 0.12 times the circumferential length of the periphery of the tire.
