Like fclaridge said from the little research that I have started to do on this seems like you can but 22.5 steel or aluminum wheels and buy adapters from ET machinery and run the 235/80 or 245/75 22.5 on the big trucks, I have by no means done this but something that I was going to look into doing to get away from split wheels. I think I will have a hard time finding someone to work on them. Also the tubeless 22.5 may turn out cheaper in the long run.
