i was wanting to know if a 16 inch wheel with 5 1/2" backspacing would work and not rub.so anyone with aftermarket wheels chime in.or of course if you know the stock backspacing let me know.thanks

 

well i have a set of 15x10s with a 5 inch backspacing and 275/50/15 and there is no rubbing

 

5 1/2 backspace should be fine on the rear. But I don't thing they will work in the front.

Stock 16x8 wheels have:
Front - 0 mm offset or about a 4 1/2 back space.
Rear - 16 mm offset or about a 5 1/4 back space.
