Yeah, with a 30, or 31" tire you should be fine, just put some gear in it (4:56) and the 4.0 tb, spacer, intake, header and efan. It will make a big difference. A 2" lift will help with clearence, you should be set. I've had a few 4 cylinder jeeps over the years and enjoyed them very much. With good gears they will climb tree's off road and open the engine a little to let it breath and there not bad on the road either.
