Still sort of trying to figure out what direction to go in. I've found some 16.5" rims that I think would work (will they clear the brakes?) and Some 22.5" rims that I think I'll need to measure to see if they are too tall.

Anyone have any thoughts on either of these?

The seller of the 22.5" rims claims they are 8-bolt but I'm waiting for photos to confirm. This seems like it would be an odd size.
