PROBLEM TO BE SOLVED: To provide a heavy load tire that is improved in durability of a bead part.SOLUTION: In a heavy load tire, a bead core 10 has a shape of a hexagon inclined relative to a tire axial direction on a cross section in a tire width direction and a relationship between a length A in the tire axial direction to a center 12 of the bead core 10 from an end part on an inside in the tire axial direction of a bead base part 18 and a length B in the tire axial direction to the end part on an outside in the tire axial direction of the bead base part 18 from the center 12 of the bead core 10 satisfies 0.6≤B/(A+B)≤0.7.SELECTED DRAWING: Figure 1

    【課題】ビード部の耐久性が向上した重荷重用タイヤを提供する。【解決手段】タイヤ幅方向断面上でのビードコア10の形状がタイヤ軸方向に対して傾いた六角形であり、ビードベース部18のタイヤ幅方向内側の端部から前記ビードコア10の中心12までのタイヤ軸方向の長さAと、ビードコア10の中心12からビードベース部18のタイヤ幅方向外側の端部までのタイヤ軸方向の長さBとの関係が、0.6≦B/(A+B)≦0.7である。【選択図】図1
