I looked very hard at those but was turned off by the price, and decided to get the Cooper ST Maxx in a 255/80/17, which is very similar to the 34x10.5/17 size-wise. I then decided to get new wheels too and went with the ST Maxx in the 255/85/16. I know that didn't really answer any of your questions, but both the KO2 and the ST Maxx in those sizes fit the stock 17" wheels. I also have a Teraflex performance leveling kit and quick disconnects. There appear to be people with the setup you are asking about on some of the other Wrangler forums.
