I see what your saying. If you make the white walls bigger and change out the centers it will set the tire off enough that it will look custom but still classic stock. It's not that old of a Caddi but just enough to keep it kinda stock and pull it off.
It would be cool if you could get the old stock Caddi spoke rims from the late 70's and 80's on that thing but i don't think anyone makes them to fit.
