Yes on the level kit, and about 5.5" backspacing should do it along with a positive offset == no rubbing.:thumbsup

Backspacing and offset go hand in hand - it all depends on the wheel width you want. If you have specs on the wheel you want we can help ya out.

Hey guys, this is a question I have also, I want to run the BFG KM2 in 35x12.5, and I was going to run the stock aluminum wheels, but with some newly aquired funds, I want to upgrade. Will these wheels work? Also what bolt pattern do we have? Is it the 8x6.5 or the 8x170?? Thanks guys!

- Bolt pattern is 8x6.5
- Those wheels have zero offset or 5" of backspacing.

Not sure if you will rub or not with your leveling kit, but I think you will.

skidooman · 02-08-2008, 01:29 PM

damn, what do the factory wheels have for offset, and backspacing?
oh and where do they rub at if they do?

Stock wheel is 17x8, +43.1mm offset (or 6.19" backspacing)

You would rub the rear inner fender of the front wheels while turning and articulating.

You will be close with that setup, maybe someone else here has that setup and can give ya a better answer.

A positive value. Mine is +14mm. My backspacing is 5 5/8". Just to clear any confusion from the other posts backspacing and offset are not the same thing.

Those values are really a close call. The only sure way to tell is a test fit. I was told to try to get a backspacing value as close to 6" as possible and have a positive offset---again they are not the same.
