If I was buying wheels new, I'd get the OEM 16 inch wheels and run 265/75R16. The 17 inch wheels from Thor look great if you have the cash. Then you can run same tire sizes as a JK since they are coming with 17s.
My 463 LWB has the stock 18s on it and I just installed 265/70r18 on it after looking/ delaying for about a year. I haven't seen any rubbing, but it sure looks like I need a lift now.
