If they're 8.5" wide and +25mm offset, yes. So they either have the wrong width, backspace or offset posted on their site.
And 5.75" backspace could cause the interference referenced in this thread, which makes me believe they have the wrong backspace posted.
An 8.5 wheel has a centerline (0mm offset) at 4.75" backspace. Add 25mm offset, which is ~1" and that changes the backspace to 5.75".
Just a quick note.... if that is indeed the root cause and the wheels are 5.75" backspace as opposed to the 5.3" backspace they [seemingly incorrectly] claim, you probably have grounds to have them swap out the wheels for the JK series which *should* work better.
Superlift clearly states in their application notes:
New wheel with maximum backspacing of 5.5" is required for installation. Factory spare can be used as a temporary spare in emergency situations.
They are definitely 17x8.5 inch wheels. I talked to AEV a while back because I noticed what they had posted online was incorrect. Whatever they posted for the offset didnt mathmatically add up to what they posted for the back spacing. If I recall corectly they said the offset was correct and they posted the wrong back spacing. I havent been on their website to see what its listed as lately. Ill check now.
EDIT: The website says +25 offset and 5.3 inches of back spacing. Obvioulsy they havent corrected it. Maybe next time trailbyfire has a wheel off he can just measure it. Or did he do that already and i missed it.

They still claim 8.5" wide, +25mm offset and 5.3" backspace: http://www.aev-conversions.com/shop/...-beadlock.html
I remember this came up a while ago because someone on JF was arguing with me, they claimed I didn't know what offset and backspace were because "according to AEV...." lol you fill in the rest
That's funny cause AEV admitted their website was incorrect.

Wouldn't the centerline of an 8.5" wheel be at 4.25"--not 4.75"?

I did measure it (crudely) at one time but it is difficult to get an accurate measurement when the tire is mounted. All I could determine was that the offset was closer to 25mm than it was to 10mm.
No because backspace is an external measurement and width is internal.
