Grigg you bring up good points - for those considering 22.5 tires here is what i am running up against.
22.5 tubeless wheels run about 300 per 6 in the Kansas City area, then they need the old tires taken off, 10 per tire, then the old tire disposed of, 7 per tire, then sand blasted and powder coated, found a place for 23 per wheel but that was the exception, most were 50 to 65.
9r-22.5 tires are the only non-obsolete tires that show as being able to be mounted on a 22.5 rim. In the Michelin truck tire book the 9r is measured on a 6" rim.
9r tires are available but Expensive. $265 was the cheapest I was quoted for a new tire. I found 2 General take off's for steer tires at 180 each and will most likely be running caps on the rear.
Used 9r tires are not real common because many old farm trucks still use them. If you do find them used, prices have been pretty reasonable - 50 - 100 per tire usually still on a rim. Finding 6 that match, good luck.
I would have been money ahead finding the useable split rim 20's with lock rings and running them.
