摘要： The present invention relates to an airplane tire and, particularly, to the crown reinforcement thereof. An airplane tire (1) includes a working reinforcement (2) located radially inside a tread (3) and radially outside a carcass reinforcement (4). The working reinforcement (2) includes at least one working dual ply (21) consisting of two radially stacked working layers (211, 212). The working dual ply (21) consists of the circumferential zigzag winding of a strip (5) having a width W over a cylindrical laying surface (6) with radius R and having, for a rotational axis, the rotational axis (YY') of the tire along a periodic curve (7). The periodic curve (7) has a period P and forms an angle A with the circumferential direction (XX') of the tire within the equatorial plane (XZ) of the tire. The circumferential zigzag winding of the strip (5) includes N periods P of the periodic curve (7) over a number T of circumferences 2πR of the cylindrical laying surface (6). According to the invention, the number N of periods P of the periodic curve (7) is an integer that fits the following conditions: (a) N*(W/sinA)=2πR; (b) Ν*Ρ=2πR *Τ, where T is an integer, (c) N*T is the lowest common multiple of N and T, and the ratio T/N is 1.8 to 2.2.
