A heavy equipment tire rim is constructed from stock shapes of metal. The base is a right cylinder. Flat radial annular disks are welded to the cylindrical base and support a steel cone having a cone angle of 15 degrees from the surface of the cylinder to support the tire bead. There are two disks for each cone to support the cone at its smallest diameter and at its largest diameter. Additional intermediate disks may be used. In another version bar stock lengths span the diagonal between the base of the outermost annular disk where it meets the cylindrical base and the periphery of the smaller radial disk where it meets the smallest circumference of the cone. The bars are in closely spaced annular series. The tire bead stop is welded to the outer circumference of the cone or to a cylindrical skirt extending the outer circumference of the cone. The stop is made of round, semi-round, or quarter-round stock. The tire bead is retained by an arc which is a quarter of a circle. All of the parts are in compression rather than tension.
