Zusammenfassung:PROBLEM TO BE SOLVED: To provide an aircraft tire which is improved so as to adapt high speed and high load, with reduced weight.SOLUTION: A pneumatic tire comprises two annular bead parts having a bead core. A carcass extends between both bead parts through both side wall parts and tread parts, and the carcass includes at least two axial inside plies extending downward toward inside of an axial direction of the bead core, from the tread. The at least two axial inside plies form folding parts by being wound to the bead core respectively. The respective folding parts are positioned on outside of the axial direction of the bead core. The carcass further comprises first axial outside plies extending from the tread to the bead core downward, and disposed on outside of the axial direction of the bead core, and at least one of the axial outside plies is formed of a reinforcement material having breakage strength higher than that of reinforcement material of the axial inside plies.SELECTED DRAWING: Figure 1 【課題】低減された重量で高速かつ高荷重に適合することができる改良された航空機用タイヤを提供する。【解決手段】空気入りタイヤは、ビードコアを有する2つの環状のビード部分を有する。カーカスが、両方のビード部分の間を両方のサイドウォール部分とトレッド部分とを通って延びており、カーカスはトレッドから下方にビードコアの軸方向内側に延びる少なくとも2つの軸方向内側プライを含み、この少なくとも2つの軸方向内側プライは、ビードコアの周りを巻かれてそれぞれの折り返し部を形成し、各折り返し部は、ビードコアの軸方向外側に位置する。カーカスは、さらに、トレッドから下方にビードコアに向けて延びてビードコアの軸方向外側に位置する第1の軸方向外側プライを有し、軸方向外側プライの少なくとも1つは、軸方向内側プライの補強材よりも高い破壊強度を有する補強材から形成される。【選択図】図1
