Backspacing

How much backspacing do I need to get for 15x8 eagle alloy 102 wheels with 33x12.50 BFG All Terrain K/O's in order to get a mean look without having the tires stick out too far past my 01 sahara flares but also not rubbing the frame?

I think 4" BS is perfect. Doesnt stick out too far yet still has a wider stance.

I think the Eagle Alloys have a 3 1/4" or 3 1/2" BS. I got them on mine with 35" tires. For the bigger tires I like less backspacing, but for 33" AT's I would have to agree the 4" would be better. Mine stick out about 2" beyond the flares.
10" wide rims will do that too, stick with 8".
Axis makes a nice wheel called the REGULATOR. They run about a 4.25" BS. They work really well on a TJ. I had them on my last jeep.

My album shows tires sticking out pretty good with Eagles.

I've yet to find an AE 15x8 wheel that fits a Jeep with any more backspacing than 3.25". That's why I stopped using AE wheels on Jeeps, their wheels stick out more than I think is good with that small amount of backspacing. At the minimum, I'd use wheels with 3.75" of backspacing which is a pretty common backspace dimension. American Racing and ProComp's XTreme wheels are available with that amount of backspacing, among other brands.

Why is that bad? They're still not as wide as a full width axle, plus you're only talking about half to three quarters of an inch over a 12 1/2" tire. That's like 5%. I fail to see much difference (having had both) you just get a little more clearance between the tire and spring/control arms.

Help me out here.....???

unless your jeep has tube fenders, a wheel with less backspacing can get hung up on the edge of the flares, instead of staying on the "inside"

Yeah, that makes sense. I think I've heard that somewhere before. I have a lot of clearance and no rubbing issues, at least not yet. But I haven't tried a ramp or to try and get all the flex possible and then get out and look. Guess I need to do that.

Jerry: we did John Bull last saturday, my first hard trail with the build up. Not a wimper or skid running through, worked awesome. My first time with a locker too!

I have 4.0" Backspacing on my rubicon and they stick out about 1" - 1 1/2" and that's with the stock fender flares that are 4 inches wide rather than the 3 inch on the other TJ's.

I run Bart 15x8's with 2" of backspacing with a 33x12.50 BFG mud terrain, it is nice and wide, really nice on side hills and other really sideways thing on the trail, plus its looks pretty mean comin down the road, I have a digital camera but I dont know how to post a pic so I cant show you how its looks, 2" BS is bad on bearings though, so 3.75" is prolly about right for what you want.
