Wheel backspacing/offset

I'm shopping around for wheels and tires but can't figure out proper backspacing and offset. I want to get some 235/75r15 on 15x7 but I can't figure out the proper backspacing. I've read the other forums and I know 3.75" backspacing will work but the wheels I want are 4" backspacing with zero offset.

Anyone have any experience fitting wheels and tires?
