This appears to imply the 17x8 is 4.5" of back space, but the terminology is one I am not familiar with. http://www.cragarwheel.com/images/me...7B3CEB5AA8.pdf

Man, those are really heavy!

As the tire size increases, you need to move the rim/tire further out. There is a lot of variance in size between different mfg's, so just because someone elses tires that have the same number stamped on the sidewall fit without rubbing, does not mean that yours will. So when you choose a backspace (or offset) err on the side of lower numbers.

For what fits with no lift, a 33x10.50 is the general recommendation with stock flares. With flats, you might fit 35's. With MC's flares, maybe 37's.

Stock backspace is in the 6.25-6.0 range. As that number goes down, the rim moves further out.

If you open the thread stuck right to the top of this modified area, you will find some recommendations. Some people report that they are fine with more backspace than these numbers, but again, tire sizes will vary quite a bit. And lift height. And axle centering. And ...

Offset is another formula to give you the same information, but it uses the rim width in the calculation, so it is not as straight forward as backspace. Use an online calculator to convert offset to backspace. Positive offsets sit further into the wheel wells, negative offsets move the rims further out.
