Re: What backspace are you running on your 2's wheels, pics??
I still don't get it...according to this (and just about every other image I find) a 0mm offset means that your backspacing is exactly 1/2 of the wheel width.
So...why does every offset/backspace calculator I find say that a 9" wide rim with a 4.5" backspacing is a -12mm offset?

Re: What backspace are you running on your 2's wheels, pics??
Exactly my point, I get backspacing-its a no brainer. Bring offset into that equation and it makes absolutely no sense.
You are correct though, a 0mm offset would put the mounting face at exactly the middle of the wheel. So a 9" wheel would indeed be a 4.5" backspace.
You mentioned yours sticking out about 2 inches so the method wheels I'm looking at with the 4.25 (which also says a -12 offset lol) backspace would come out a little farther and should be perfect with my offroad flares.
I'm going to call TireRack right now and see what they say about these measurements. If they are what their site says I'm going to order those wheels with the Kumho Road Venture MT's in 315.

Re: What backspace are you running on your 2's wheels, pics??
I also appreciate commenting on this thread. I have posted a few wheel threads and never gotten many replies.
So Charlie at TireRack did confirm those backspaces I mentioned on these Method wheels. I placed an order for the 17x9 with the 4.25" backspace. I'm going to measure the backspace when they arrive next week. According to various calculators a 4.25" backspace on a 9" wide wheel is a -19 offset.....we shall see!
