I run 34x10.50 LTB's on my YJ and love the way they wrk only thing I don't like is the tread life, they wear very quickly, so I picked up a second set of tires and wheels and now I run 33x9.50 BFG AT's on road and the LTBs off, this to me is a great way to have a Jeep set-up, I personally wouldn't want a wider tire 99% of the time, only time I want wider is when I'm in a bottomless mud pit, then I would like to have more floatation, but that isn't where I spend most of my time, so I deal w/ it, heck thats what staps and friends are for, lol.
Now w/ that said, how do you use/plan to use your Jeep, that will make a big difference on what you want for tires.
