摘要： The present invention relates to a crown for a tire for an aircraft, and the aim of the invention is to decrease the size and thus the weight of the pieces of the tread, in the event of an accidental separation thereof from the tire, without the use of additional devices external to the tire, and thus without reducing the payload of the aircraft. A tire for an aircraft includes a tread (2), and the tread (2) includes separate recesses (5) extending radially between a bottom surface and the rolling surface (3). According to the invention, each recess (5) has, in the rolling surface (3), an open surface (6) inscribed in a circle (7), the centers (O) of the circles (7) circumscribing the open surfaces (6) of the recesses (5) being axially distributed over at least a portion of the axial width (1) of the rolling surface (2).

摘要： The present invention relates to a tire for an aircraft and in particular to the crown of a tire for an aircraft, and the aim of the invention is to decrease the size and thus the weight of the pieces of the tread, in the event of an accidental separation thereof from the tire, without using additional devices that are external to the tire, and thus without reducing the payload of the aircraft. An aircraft tire (1) includes a tread (2) which is to contact the ground via a rolling surface (3) and which is radially arranged between a bottom surface (6) and the rolling surface (3), the tread (2) including at least two circumferential ribs (4) adjacent to at least one circumferential groove (5), each circumferential rib (4) extending radially between the bottom surface (6) and the rolling surface (3) and axially between two ridges (7) in the rolling surface (3), and a crown reinforcement (8) which is radially interior to the bottom surface (6). According to the invention, a separation layer (9) is arranged radially inside at least one circumferential rib (4) between the bottom surface (6) and the crown reinforcement (8), axially between the two ridges (7) of said circumferential rib (4), in the rolling surface (3), and circumferentially over at least a portion of the circumference of the tire (1), and the radial distance (d
1 ) between the separation layer (9) and the bottom surface (6) is equal to at most 1 mm.-
