18 inch wheel

On my 18" Simmons wheels, 4.32 backspacing on the front (18"x8.5") and 4.75 on the back (18"x9.5"). That back spacing would be fine on a 18"x8.5" rear as well without rolling the fender, because I still use a 1/4" spacer to fill the wheel well with a 325/40/18 tire.

Will 4.5 backspace work all around
 
ttypewhite: Are you running 18x9.5 with a 325/40-18 tire?
I tried my 325/30-19, but it touched the notched frame and just kissed the rolled fender.
However, it was on a 19x12 rim.

Yes sir . No frame notch, just a rolled lip and 1/8th " spacer, not 1/4", my mistake earlier.
