28 inch tires on 68 barracuda.
I have a 67 Barracuda with stock spring running a 275/60/15 with no problems... it is a 28" tall tire. I had to use offset shackle kit to get the beefs under there however but a 28" did fit.
I have around a 1/2 from the quarter fender. I have yet to rub and I have abused this car pretty good LOL!
I thought I had a better picture.
