I have the standard 10 bolt with 8.25 X 20 tires. I've not been able in the last few months of looking to find 22.5 rims. I'm sure there are new ones out there, but I am a teacher, and that means no money for new stuff. For my other truck I have been able to barter for many things and buy only a few. That could be why it is taking so long to get things done. Weather permitting, I plan to go tomorrow and pull one wheel from the 19.5 set to try on my truck. Then we will go from there.
Another question: It looks like the frame isn't full length on the tilt bed, it is filled with big timbers for strength. Is that normal?
