How much backspacing for XX tires?

I just got my TJ and I've been saving money to start 'improving' it.
I'm trying to make a list of all the things I want/need (having just gotten the jeep, I think 'need' is more appropriate), but since I am so new to this I need ALOT of help. That being said:

I want to run a 2" lift with 32X11.5s, but I don't want them to rub. Right now I have stock wheels (I think they have 4" of back spacing), but I am thinking of buying a set of Cragar Soft 8s (15X8s). I want to make sure I get the correct back spacing so I won't have ANY rubbing. My jeep is my DD and I don't have alot of cash to put into new sets of tires because I'm burning them off on the inside of my wheel wells when I turn. I've not overly worried about the tires sticking out past the fenders....it just gives me an excuse to buy new ones.

Any help that anyone can provide would be appreciated. Pictures TJs with a similar setup would be great too.

Thanks

Stock wheels have 5" or more.Get 3.75-4.5" backspacing.The less backspacing,the farther the wheels will stick out.

Thanks for the help

I do have one more quick question....if I run 32X11.5s with the 4" of back spacing, how much extra coverage (if any) will I need for my fenders? (I'm pretty sure I need the wheels to stay completely covered here in MA)

Will it be enough to have an excuse to pick up some Bushwacker or Xenon flat fenders?

11.50 wide tires on 4" backspaced wheels will stick out about 3".

You'll need 6" wide flares in order to cover them.

I have a 2" lift with 32x11.50 (BFG AT's) on ARA767 15x8 with 4" of BS and that's pretty much standard I think.

Like wheelin' said above, you'll need 6" wide flares yep. I installed a set of Xenon Flat fenders this past summer (after getting 2 tickets for the tires not being covered) and they look great.

I got 4.75" backspacing with 32s and a 2" lift and rub on the control arms at full lock. Disconnected I rub on the sway bar, but that's more of a lift height issue exaggerated by the deep backspacing. Go with 4.5" or less, perfect would be about 4.0".

please for the love of god do not buy bushwacher pocket flares, unless you are a street queen. the bushwackers are known to be brittle when cold and break offroad, i would look into the zenon flat fenders or warn fenders

Don't worry I would NEVER get the bushwacker pocket flares. I've heard their reputation and I know to aviod them. I was thinking of the Bushwacker flat fenders tho....I was reading up on them, they use a different type of plastic that they claim is much more durable (and alot less brittle) then what they used in their old pocket fenders. But I'm still on the fence whether to go with the Bushwacker flats or the Xenons. I only found one guy(on the forum) who wrecked them while wheeling, they didn't break, only creased, but he said he used a heat gun to straighten them out.
