PROBLEM TO BE SOLVED: To provide an improved pneumatic tire which can stand high speed and high load, and which can be made lightweight.SOLUTION: A pneumatic tire of the invention comprises: two annular bead parts; a carcass; and a belt reinforcement layer. The carcass extends between the two bead parts, through side wall parts and tread parts. The carcass contains at least two axial inside plies extending downward in inside of an axial direction of a bead core from the tread part. The at least two axial inside plies are wound to the bead core respectively to form a turned up part. The respective turned up part is disposed on outside of the axial direction of the bead core. The carcass contains a first axial outside ply extending downward toward the bead core, from the tread part, and disposed on outside of the axial direction of the bead core. The axial outside ply is separated from at least one of the turned up part by a first spacer layer.SELECTED DRAWING: Figure 1

    【課題】高速および高負荷に耐え、かつ、軽量化を図ることが可能な、改善された空気入りタイヤが必要である。【解決手段】本発明に係る空気入りタイヤは、2つの環状のビード部と、カーカスと、ベルト補強層とを有する。カーカスは、サイドウォール部およびトレッド部を介して2つのビード部間を延びている。カーカスは、ビードコアの軸方向内側をトレッド部から下方に延びる少なくとも2つの軸方向内側プライを含み、上記の少なくとも2つの軸方向内側プライは、それぞれターンアップ部を形成するようにビードコアの周りに巻かれ、各ターンアップ部は、ビードコアの軸方向外側に配置される。さらにカーカスは、トレッドからビードコアに向かって下方に延び、かつ、ビードコアの軸方向外側に配置される第1の軸方向外側プライを含み、軸方向外側プライは、第1のスペーサ層によってターンアップ部の少なくとも1つから離れている。【選択図】図1
