Tyre for an aeroplane, comprising - 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 independent cavities that are not connected to one another, - each cavity having, in the tread surface, an opening surface inscribed inside a circle, where the centres of the circles, circumscribed at the opening surfaces of the cavities, are distributed axially, over at least part of the axial width of the tread surface, with an axial spacing (p Y) at least equal to 0.02 times and at most equal to 0.12 times the circumferential length of the periphery of the tyre, where the centres of the circles, circumscribed at the opening surfaces of the cavities, are distributed circumferentially, over at least part of the periphery of the tyre, with a circumferential spacing (p X) at least equal to 0.02 times and at most equal to 0.12 times the circumferential length of the periphery of the tyre where the cavities, distributed respectively axially and circumferentially with axial pitch (p Y) and circumferential pitch (p X), constitute a two-dimensional network of cavities made up of rectangular or square mesh cells, characterized in that the opening surfaces of the cavities have an oblong shape, and in that, each cavity having a mean plane (P 1, P 2) oriented perpendicular to the opening surface and along the longest dimension of the opening surface, the mean planes (P 1, P 2) of the cavities are distributed between a first family of mean planes (P 1) that are mutually parallel and make an angle (i) with the circumferential direction (XX'), and a second family of mean planes (P 2) that are mutually parallel and perpendicular to the mean planes (P 1) of the first family. - 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 independent cavities that are not connected to one another, - each cavity having, in the tread surface, an opening surface inscribed inside a circle, where the centres of the circles, circumscribed at the opening surfaces of the cavities, are distributed axially, over at least part of the axial width of the tread surface, with an axial spacing (p Y) at least equal to 0.02 times and at most equal to 0.12 times the circumferential length of the periphery of the tyre, where the centres of the circles, circumscribed at the opening surfaces of the cavities, are distributed circumferentially, over at least part of the periphery of the tyre, with a circumferential spacing (p X) at least equal to 0.02 times and at most equal to 0.12 times the circumferential length of the periphery of the tyre where the cavities, distributed respectively axially and circumferentially with axial pitch (p Y) and circumferential pitch (p X), constitute a two-dimensional network of cavities made up of rectangular or square mesh cells, characterized in that the opening surfaces of the cavities have an oblong shape, and in that, each cavity having a mean plane (P 1, P 2) oriented perpendicular to the opening surface and along the longest dimension of the opening surface, the mean planes (P 1, P 2) of the cavities are distributed between a first family of mean planes (P 1) that are mutually parallel and make an angle (i) with the circumferential direction (XX'), and a second family of mean planes (P 2) that are mutually parallel and perpendicular to the mean planes (P 1) of the first family.
