The 22.5" one piece rims with the 5/10 lug and the 5.25" center hole are getting hard to find. That lug pattern is available in the 19.5" rims, but they will look small in your wheel openings.
The 22.5 tubeless rim is the direct replacement for the 20" tube type rim. To keep the same tire diameter you go UP one tire size number when going from 20 to 22.5.
7.50x20 = 8.25x22.5
8.25x20 = 9.00x22.5
9.00x20 = 10.00x22.5
10.00x20 = 11.00x22.5
