I am fitting a 275/50/15 currently with 3 5/8 backspace with the stock small bolt pattern offset. It needs the fenders rolled but just barely, if my car didn't sit so low rubbing would not be a problem.
Ages ago I ran a 265/50/14 I believe on a 3 3/4 back space 14x7 slotted mag. I also ran a 26x8.5 slick on a 14x8 rim.
The pic was 1997 or so, I miss those rims. I'm not sure what tire was on it then. Either a 245/60/14 or 265/50/14
