you have two issues...
the first is getting the Jeep to move in general...assuming you have 4.10 gears? (you didn't say auto or 5-spd, and some of the autos had 3.73 paired with the 4-bangers)...it'll be sluggish around town either way, but somewhat livable with the 4.10's...
the other is clearance, and you'll be all into the fenders (assuming they're stock) if you wheel it and disconnect the front sway bar...you'd be a lot better off if you really wanted 33's to add a 1" or 1.25" BL...
31's would be a great setup, and you could do a belly-up skid instead, which would be the equivalent of going from say 31's to 37's as far as breakover angle goes...
