@EdPruss how did you make sure to get the hols drilled hub centric? Or did you have a machine shop do it?
Given the easy availability of modern 22.5" wheels in 8.75" pilot, (I have a set, there is plenty of metal there for strength) this seems like a good option if you don't care about the looks of the other set of holes. While getting all this done would be kinda expensive, it would be a one-time expense that would ensure permanent, easy availability of modern tires-even used ones that you can find for $100 each-for as long as 22.5" wheels and tires remain a common thing.
