Advise on Rims/tires 67 Barracuda FB

I think it should fit fine. I have 15x10s on the back of mine with the same backspacing and a 265 tire and it fit with a slight roll of the fender lip. The 255 on a 8" rim should be in a full inch from where mine are. Lots of folks running that 215/60-15 on the front with no problems.
