255's on the front of my Demon, 25" tall. It all depends on your wheel backspace, ride height, front suspension, brake offset.....These have 8" wide w/ 6.5" of BS, nothing stock on this car though.
I have full turn w/ the racknpinion. I bought a couple of craigslist mustang wheels measured the backspacing and ordered my wheels accordingly. The pic is about 1/2" lower than ride height
