You can run 275/50R-17s on an 8" rim. That's what I have on mine. You can either run Falken's, Nitto's or M&H Drag radials in this size. My backspacing is either 4.5" or 4.75" but my rear is about .75" - 1" narrower than stock.
 235/40R-17's on the front.  The 9.5" will fit and some folks have run 285's on them. http://www.highperformancepontiac.co...tiac_firebird/ .

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.
