Any tubeless would be in the half inch sizes, i.e 16.5, 17.5, 19.5, and 22.5. Nobody makes normal looking ones today. A company called American Wheel Specialist in Pasco, WA, sells new wheels in the 19.5 x 6" size having the 5 lug x 8" pattern, but they have a much wider wheel face. We think they were designed to clear disc brake calipers. I can post a pic if you want.
Grigg told me his 22.5s are the 5.25" (4ea) and 6.00" (4 ea) sizes. That says they are the earlier ones made probably by Budd and should have part numbers 69930, 76310, or 76320 respectively. Could be K-H part numbers 40159 (5.25") or 41778 (6.00"), but I doubt you'd ever find those numbers since K-H only put them on paper tags on the inner mounting surface. The later 22.5s were made in 6.75" width and are Budd #s 72540 or 89810, or Accuride #27759.
If he wants the used 19.5s, the only manufacturer I've found having made them is Budd. The earliest 5.25" wide ones were part #s 72070 and the 6.00" wide variety were #s 73160, and most common #89340. Stu
