front tire height '69 GTO
what is the tallest 15" tire I can put on the front of my 1969 GTO without worrying about the tire hitting on turns?
I have 275-60-15 on the rear which are 28" tall thanks rrrbeee |

I would say the 215/70-15 at 26.85" tall.
Provided of course that your wheel has enough backspacing, say at least 4.25" of backspacing for a 7" wide wheel which is pretty much equivalent to a factory 15X7" Rally II wheel. |

I'm running 235/60/15 on a 4" back space on the front...255/60/15 rear 69 GTO I think they are 27".

Agree with all the others. 27" tall 70 or 75 series is about the max.
