Abstract: An object is to improve durability without increasing the tire mass.An aircraft pneumatic tire (10) includes: a carcass ply (12) that straddles between a pair of bead portions (24); an inside belt layer (14) that is provided at a tire radial direction outer side of a crown portion of the carcass ply (12); an outside belt layer (16) that is provided at the tire radial direction outer side of the inside belt layer (14) and that is configured by a cord of cord configuration elements that have been twisted together; a belt protection layer (18) that is provided at the tire radial direction outer side of the outside belt layer (16) and that is configured by a cord of cord configuration elements that have been twisted together; and a low elasticity portion that is provided at at least one of the cord of the belt protection layer (18) or the cord of the outside belt layer (16), and that has a lower elasticity than other length direction portions of the cord (32).
