You want stock like performance with 35's, you're going to have to regear to 5.13's or 5.38's. That's the sweet spot to shoot for on a 2.5L. You can run 4.88's but you'll really want to go lower. Although that requires an axle swap. You'll probably want to consider an axle swap or upgrade of some kind to beaf up the rear axle. Don't forget to address the rear driveshaft. The angle to run 35's will require a SYE. Like what was mentioned by the others, 35,s with enough lift to clear them will make your brick into a bigger brick. You'll need at least 5" of lift.
Honestly, if you want to go bit without doing too much, I'd consider going with 33x9.5R15's. They are still 33's but they are narrower so there is less rolling and wind resistance. Not to mention they are lighter then standard 33's. You won't need to regear. If you do though 4.88's would be good. You'll need less lift which means it will be a bit lower and act less like a sail. If you get the proper wheel BS your tires won't stick past the stock flares and act more like a sail.
Once you move to 35's, the Jeep becomes less of a Daily Driver. If you don't have to commute then all the better. I run 35's with 6" lift and 4.56's. Commuting was always a PITA since I don't have enough power to pass unless I really plan it ahead of time. It gets frustrating and wears you down as well. My commute was 40 miles.
