Aircraft pneumatic tire

An aircraft pneumatic tire comprising:

• a pair of bead cores (6);
• a radial carcass (7) including one or more carcass plies (7a) extending toroidally between both the bead cores (6);
• and
• belt layers (10) that are disposed on an outer circumferential side of a crown region of the radial carcass (7) and reinforce the radial carcass (7),characterized in that
• the belt layers (10) include
• a spirally wound belt layer (20) that has one layer or a plurality of layers (21, 22, 23) stacked and in which a ribbon-shaped first strip material (26) with a first belt cord (26a) including organic fibers and being covered with rubber is spirally wound, and
• zigzag belt layers (30) in which a ribbon-shaped second strip material (36) with a second belt cord (36a) including organic fibers and being covered with rubber extends and is wound in a circumferential direction while bending zigzag by being folded back at width directional end edges (30a) to an outer circumferential side of the spirally wound belt layer (20) and in which a plurality of layers (31, 32, 33, 34) are stacked,
• a maximum width Ws of the spirally wound belt layer (20) is wider than a maximum width We of the zigzag belt layers (30), and
• a width Wse of the second strip material (36) is wider than a width Wss of the first strip material (26).
