ABSTRACT:
A heavy loading tubless tire comprising a bead portion which has a buried bead core bundled of a plurality of bead wires and having a polygonal section contour and which has its bead base composed of two regions: a region W.sub.1 located at the side of the bead heel and inclined at an angle substantially equal to the angle .theta. of inclination of a rim base with resepct to the axis of tire rotations; and a region W.sub.2 located at the side of the bead toe and inclined at a larger angle than the angle .theta. of inclination of said rim base, wherein the improvement resides: in that the width of the region W.sub.2 at the side of said bead toe measured in the axial direction of tire rotations is within a range of 30 to 70% of the total width of the bead base measured in the axial direction of tire rotations whereas the width of said bead core measured in the axial direction of tire rotations is at least 40% as large as the total width of said bead base; and in that the bottom side of the polygonal contour of said bead core at the side of the bead base is composed of a bottom side a.sub.1, which is located at the side of the bead heel and inclined at an angle .theta.a substantially equal to the inclination angle .theta. of said rim base, a bottom side a.sub.2, which is located to merge into said bottom side a.sub.1 and inclined at an angle .theta.b larger than the inclination angle .theta. of said rim base, and a bottom side a.sub.3 which is so located at the side of the bead toe as to project from the extension of said bottom side a.sub.1 toward said bead base.
