I was wondering what size of wheels and tires you have and what backspacing you have for the fronts and rears? I plan on getting these wheels for my trans am and I want to fit the fattest tires I can all the way around.

This may get moved to another section but....

Boze Pro Touring
17 x 8 (Front) with 4.5" bs - 255 40 17
17 x 10 (Rear) with 5.5" bs - 275 40 17

18 x 8 (Front) with 4.5" bs - 245 40 18
18 x 9 (Front) with 5.5" bs - 275 35 18
18 x 10 (Rear) with 6" bs - 295 35 18

These measurements are for stock brakes and calipers. Aftermarket brakes may affect bs (backspace) measurements.
