Does anyone know what the correct backspacing is for 22" X 9.5" wheels? I see them listed with like +40mm and +12mm? I don't understand that stuff. I assume the +40mm would stick out, so the +12mm is what I would be looking for? I DO NOT want the wheels to stick out past the fender.

This would be on an 07 NNBS Tahoe, which I would think is the same as all the 99 & up NBS?

TIA,
S.C.

 

stock for nnbs is 30 offset and 6" backspace
pre 07 was 18 mm and 5.5

 

The more offset the more the wheels tuck into the fenders. You will want to go with a +40 if you don't want them to stick out.

And the 07+ trucks/suvs use a larger offset than the pre 07s to tuck. A lot of the pre 07 guys are actually using the cast 07+ wheels since they are cheaper than billets and still tuck.

 

Thank you very much guys!

 

the 07's have a wider track, hence more offset needed to keep the wheels inside the
fenders
