Even if you find the original 56-59 Chevy 22.5 wheels you more than likely can't run the tires you want without first having the rims swapped for wider ones.

On the quote from wheelsnow,
I'm curious how they'd make them, what parts would they use, and how would it look?
So far I haven't seen a 22.5" wheel center with 10 on 7.25" pattern that looks right (other than the real thing). Any other wheel center adapted to that bolt pattern is to large on the flat surface in the center and looks odd.

That price is expensive, but if it's a good looking and professionally made "new" wheel it's probably a reasonable price.
On a different yet similar matter I've gotten a quote from Mike for some Dayton rims, and was happy with the price, just haven't found the money yet...
