I think you are asking 2 questions though.....you don't need to duplicate the exact back spacing of your factory wheels (unless you are asking about the Helo wheels in your sig line....then I'm not following you) on your new ones.....there are advantages to having less back spacing. Read the thread and let us know if you have another question.

Guy at summit said he has to know in order to
know if the rims I order are right.
Am putting BFG 255/75R17'S on the Cragers.
Thought I could order the 5x5 pattern 17's and all would be good.
Do I have to pull the tire to determine backspace or?????

Guess you didn't even look at the "Wheels & Tires" FAQ he linked?
Let me help you, here are a few excerpts from that link...
255/75R17'S are a stock tire size. You can use factory backspacing on the new rims. If you want a wider stance/look, then get something in the range above.

and/or are still running factory wheels which have 6.25" of back spacing.
Backspacing on all factory wheels is 6.25"
What back spacing will I need on my wheels in order to clear 12.50 wide tires?
A: I would recommend that you do not exceed 4.75" of back spacing and even at that, you may still have some minor rubbing up front at a full turn. Also, I would recommend that you do not go any less than 3.75" as anything less would cause your tires to stick out very far past the fender flares. Any back spacing within this range should work out great.

it also makes sense to get rims with 4.75 BS so that if you do decide to get wider/larger tires you won't have to use spacers or get new rims with the right BS and spend more money. These stock rims have BS like a front wheel drive car requires. Why jeep did that i'll never know. STooooopIDdd!!!

So in the end, did you find your rims? ...and how much did they cost? I actually have a set of Spidertrax Spacers but am considering switching to a set of Soft-8's. I guess in my case, that would be 17x7.5x4.75bs (for the stock Rubi tires).....if I understand everyone correctly.
