OK gotcha, I reckon those rears might just about clear, mainly as a result of the stretch. They're basically 6mm further out than mine at the edge of the tread but mine sit quite square on the shoulder as they're on a 9.5" rim. You also might help the situation with a narrower tyre such as a FK452. However, they should fit easy with a roll
Your What tyre are you thinking for the front? I reckon the widest you could go would be a 245 and then it would probably need to be a 35 profile.
How hard is your suspension? All my stuff relates to relatively soft Bilstein based suspension - rock hard suspension makes life easier with aggressive offsets (but has countless other downsides as most people know).
