An elongated metal strap is formed having a length, width and thickness approximating the circumference, width and depth of the rim groove. A series of spokes are welded endwise to that strap at spaced-apart locations therealong and then the strap is bent into a hoop with the spokes extending radially inward and seated snugly in the rim groove.
