To provide a pneumatic radial tire having a bead core that is lightweight without sacrificing strength and is improved.SOLUTION: A pneumatic radial tire has a bead part having a bead core 30, in which a flipper 60 is wound around the bead core 30, the flipper 60 is formed of a reinforcement material, the flipper has an axial inside leg 62 extending to radial outside from a reference line XX' to a radial distance Li, the line XX' extends through a geometrical center of the bead core, and the radial distance Li is equal to or larger than a bead radius when measured in a radial direction from the line XX'.SELECTED DRAWING: Figure 3

    【課題】強度を犠牲にすることなく軽量である改善されたビードコアを有する空気入りラジアルタイヤを提供する。【解決手段】ビードコア30を備えたビード部分を有する空気入りラジアルタイヤであって、ビードコア30にはフリッパー60が巻き付けられており、フリッパー60は補強材料で形成されており、フリッパーは基準線XX’から半径方向距離Liの位置まで半径方向外側に延びる軸方向内側レッグ62を有し、線XX’はビードコアの幾何学的な中心を通って延び、半径方向距離Liは線XX’から半径方向に測定したとき、ビード半径と等しいか、またはビード半径よりもより大きい。【選択図】図3
