I just lifted my xj 4.5" and put 32" BFG muds wrapped around American Racing 767's with 4" of backspacing on about a week ago. I've only wheeled it twice with the lift and tires, but I absoloutlely love them so far. I dont know if your looking at mud terrains, but thats what I would reccomend. They wear virtually the same as all terrains, aren't loud at all (as far as BFG's go at least), and offer better traction throughout a broader range of environments.
I paid a little over 900 bucks out the door including tax and new lugs. As for the SYE....well, Im still looking for one myself. HTH man
