I've have four 225/50/15 p-zero's on 15x7 4.25 bksp on my 68 once. My car is very lower so it looked OK, but still a little small.
That short tire with my low ride height setting made the car seriously low. Like the front k-member would slam head onto to those parking space curb stop. No scraping, just thud and stop. Would scrap my exhaust in the middle of the car do to high centering.
