PROBLEM TO BE SOLVED: To provide an improved aircraft tire having durability to high speed and heavy load, and satisfying weight saving requirement.SOLUTION: The carcass of a pneumatic aircraft tire has: at least two inner plies 1, 2, 3, 4 which are wound around an annular bead member 14 from inside toward outside in an axial direction and extend to outside in a radial direction toward a crown to form folding parts 10, 20, 30, 40; at least one outside carcass ply 5, 6 extending inside from the crown in the radial direction and outside the annular bead member 14 in the axial direction and partially wound around a bead to end at terminal parts 50, 60; and a barrier ply 100 positioning between an inner liner 13 and an innermost ply 1 in the axial direction. The barrier ply 100 has a first end part ending in the shoulder area of the tire and a second end part 120 having a terminal part positioning below the outside carcass ply.SELECTED DRAWING: Figure 2 【課題】高速と高負荷と軽量化とを満たす、改良された航空機タイヤを提供する。【解決手段】空気入りタイヤのカーカスが、環状ビード部材１４の周りに軸方向の内側から外側に向かって巻かれ、クラウンに向かって半径方向外側に延びて、各折り返し部１０，２０，３０，４０を形成する少なくとも２つの内側プライ１，２，３，４と、クラウンから半径方向内側に、環状ビード部材１４の軸方向外側に延び、ビードの周りに部分的に巻かれて、末端部５０，６０で終端する少なくとも１つの外側カーカスプライ５，６と、インナーライナー１３と軸方向の最も内側の内側プライ１との間に位置するバリアプライ１００と、を有する。バリアプライ１００は、タイヤのショルダー領域内で終端する第１の端部と、外側カーカスプライの下方に位置する終端部を有する第２の端部１２０を有している。【選択図】図２
