RE: 265/70-18 - Not without trimming. It can be done, but unless you're willing to break out the cutting tools I'd recommend going with 265/65-18s. That's my 'default' tire size recommendation for these rigs.
(as a side note, I have a set of 275/70-18 Cooper STT Pros arriving in about a week, but I'm not averse to a little cutting)
Do you have a thread to discuss the plan and results? I did a test fit of both 305/60x18 and 275/70x18 and found both to be seriously problematic in articulation and turning. Even if you were to cut more fender liner it wouldn't be enough, the actual outer fender edge will have to be "relieved" or else the tire will just grind into it up front and in the rear it will be right against the 3 and 9 o'clock positions. I'm excited to see what you end up doing !
