Tire Size for 5.5 small bolt rally wheels on 64 Valiant 200

You think 245s on a 14x7 wouldda fit?
if i had a rim with more backspace and rolled the inner fender lip and went to stock, or nearer-er stock height, i think so.

the biggest limiting factor on the early bodies is how the quarter curves in, so for wide stuff you need to either jack the *** end up all stink bug, relocate the springs or run a deep backspace or offset, or a combination of any or all of those.
