    摘要： 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).

    摘要： Provided is a pneumatic tire which may have a reduced weight and increase fuel efficiency while securing durability.Provided is a pneumatic tire which comprises, as a skeleton, a carcass 2 extending toroidally between a pair of bead cores 1 individually embedded in a left-and-right pair of bead portions, and is provided with an oblique steel belt layer 3 which is arranged on the periphery side of a crown portion of the carcass 2 and in which a plurality of cords extending obliquely with respect to the tire circumferential direction are arrayed, and a circumferential direction belt layer 4 which is arranged on the periphery side of the oblique steel belt layer 3 and in which a plurality of cords are arrayed substantially in parallel with the tire circumferential direction. The cords 5 of the oblique steel belt layer 3 are placed side by side in a belt width direction in a unit of a bundle of a plurality of parallel steel filaments and the cords 6 of the circumferential steel belt layer 4 are placed side by side in a belt width direction in a plurality of twisted filaments.
