22.5's
I have seen a fjord with 22. 5's on it and it looked great! I have seen a signature on here that said he had them on his w350 I believe. But, both these trucks were dually's I don't think you could find single 22. 5 rims very easy. Regardless the truck I looked at had special machined adapters to bolt them to the stock hubs. Hope this helps. I would love to run a 19. 5 or 22. 5 myself but can't justify the expense!
