An aircraft tire (1) comprises a working reinforcement (2) radially on the inside of a tread (3) and radially on the outside of a carcass reinforcement (4), comprising at least one working bi-ply (5) made up at least in part of two working layers (6, 7) and comprising, at each axial end, an axial-end additional thickness (51). Each working layer (6, 7) is made up of an axial juxtaposition of strips (8) of width W, a strip (8) having a mid-line (81) extending circumferentially along a periodic curve (9) forming, in the equatorial plane (XZ) and with the circumferential direction (XX′), a non-zero angle A and a radius of curvature R at its extrema (10). The ratio R/W is at most equal to N/(1−cosA)+½, such that each axial-end additional thickness (51) comprises at most (N+2) working layers.
