The pic of my 65 had 275/60-15s on a 10" rim. It was tight! I went to a Hoosier QTP 29x10.5-15 and had to mount on a 8" rim (which was the minimum recommended in their catalog) and it fit great with room to stick your hand in between tire and qtr. I think it was 4.5 backspace. It looks great now, really fills the well. Sorry no pics yet of new set up. Springs in stock location and only the lip of quarter had been rolled a lil.
