Question about rear wheel size/backspacing/tire size
If I put 255/60-15 BF tires on a 67 GTO, what would be the best width...7" or 8", and how much backspacing??? 4.5? I was thinking about getting some Cragars. And for the front I would want 15"x7's for sure...wonder what size tire for front. I like the wide rear and narrower front look. Any pics, or comments would be awesome, thanks

I have the exact same question so I thought I'd bring this post back.
I want to use 15x7 Rally II wheels with a 4 1/4" backspace. will it work? looks like it would be close. |

I have 17x8 with 255/45 17 on all 4 corners with 5.5" back space. Stock width 67 rear...no fitment issues, no rubbing, wheel well lips are not modified. The front has 12" Baer discs on B body spindles. I can't say if that changes the front track width or not, but if it does it can't be by much.

I recommend using an online wheel & tire fitment calculator such as WillTheyFit.com. Enter your current wheel & tire specs, then enter your desired wheel & tire specs, and it will show you how/where the dimensional fitment will change. You can then take that info and look at your car to determine if you will have clearance issues.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
