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

Appreciate the info Mike. From what I have determined via research and comparison with other pictures is that I have 10 lug 8.75" bolt circle wheels that are hub piloted. Not sure on center bore yet, likely need to get back to the shop at the other farm and physically measure them. My guess is that its either the 5.25 or 6 inch center bore. I assume that rear wheels should be the same as fronts for the trucks? As in they wouldn't have made different lug bolt pattern/center bore/lug piloted on the rear axle from the front axle on the same truck? I don't care about single piece wheels, im fine with 2/3 piece lock ring style so long as they are rated for my loads.
