A 1952/53 GMC 450-30 came equipped with hub piloted wheels made by the Motor
Wheel Corporation. They were either MW 83692 (GMC 2267606) which was a 20" x 7.00" having a Firestone RH5 locking style rim, or a MW 83638 (GMC 2263243) which was a 20" x 6.5" having a Goodyear LBW locking ring rim design. Being hub piloted the wheels have a 6.25" center hole.
The Accuride #28157 mentioned above is stud piloted with a 6.5" center hole, so you'd have to have a spacer made to allow its use. If you want to do the search, Motor Wheel Corporation began production of tubeless 22.5s in 1956 that will be exact replacements having the 6.25" center bore and using their compression washer lug nuts. There were four made, #84820 that is 6" wide, #84923 that is 6.75" wide, #84823 also 6.75" wide but with slightly more offset, and #84826 that is 7.50" wide.
I have a 1970 National Wheel and Rim Association reference showing them in use through 1969 (and likely beyond since it's a 1970 reference) under the NWRA cross reference code
X46170 for the 6.00" rim, and X46180 for the 6.75" rim. I have no record of Budd or K-H having ever made such a wheel, but it's possible they did and they fall into a gap in my references.
I have a 1979/80 Accuride catalog showing there were two made by them matching the description. Both 6.00" wide with part numbers 25702 and 26494. I don't know why two of the same width, unless it's again because of differing offset designs. This is the last reference I find for a hub piloted wheel having the 6 lug x 8.75" pattern. My references go up to 1990.
