I'm running that size rim with a 275/60-15 tire on my '68 Barracuda. No rubbing even on the roughest roads or hardest launches. I used two passenger side 3200lbs SS springs, sway bar, properly adjusted slapper bars and Koni shocks.
When it becomes time to replace those Koni's I'll buy the QA-1 single adjustable shocks like I did on the front. Great shock for the money and the adjustment range is spot on.
