I did it on my '98 TJ with the stock Gamblers (5.75" backspacing IIRC) -- added a washer or two to the steering stops to prevent lock-to-lock rubbing. Had about a quarter to half inch clearance to the rear spring perch, which was fine on the street.
Offroad I always aired down which allowed the tire to shrink (like a balloon) giving me adequate clearance from the spring perches. Had a slight amount of rubbing (just enough to 'shine the paint') on the front CAs during full articulation.
This was with BFG muds, a RE 3.5" lift on a 4.0l, auto, D44 equipped '98. YMMV.
