I just got 2 free 16" rims so I was wondering, will 255/50/16 BF Goodrich drag radials fit on the back of of my 92? It has 15's on it for every day driving. I just want these for when I go to the track.

Are we talking about F-body 16" x 8" wheels? If so, 255/50/16 drag radials should fit fine. That's only about a 1/2 inch more than a stock tire.

i have 285/40/17's on a 17x9 rim out back, plus my iroc is lowered aproxamately 2 inches. you will be fine but you have to be careful with back spacing. but with 8 inch wide rim you should be fine the stock irocs are 16x8 with a 245/50/16 and there is plenty of room left.

Sweet, Thanks
