Charlie,
Depending on the backspace of the Pontiac wheels. that will determine how close the tires will come to the frame rails. 255/ 60 is a pretty wide tire..
You might have to do the wheel spacer trick...

I tryied on 235 70 15, on a 15x7 rim had only 3"of space from the frame rails to the tire

If you have the same backspacing as my Monte SS alloy wheels, (I think it's 3.75") the 255/60R15s fit fine. That's what I run.

Thanks. If it ever quits raining I'll go out and measure them. Looking for front size recomendations. It's gonna get driven. I'm thinkin' 205/65 or 215-225/60-15's.
I know the Monte SS had 215/65's but I dont want to run quite that tall a front tire.
thanks

I run 235/60R15's on the front. No problems with lock-to-lock, very minor rub on the "lip" of the inner wheelhousing if I ran over speed bumps at 40 MPH with the stock mushy springs. I don't know how it'll be with the B-body spindles yet, but Doug @ Global West says it'l be fine.
