None dude, check my Jeep site. I have an 03' with no lift and 31 m/t's on there on the Paragon Pages. The 04 mod page shows the same tire with a lift on it.
Yeah, you don't need a lift to clear 31's, but a small lift (2" maybe) wouldn't hurt and will give you some room for flex when the swaybar is disconnected.
I have a 2000 Sahara and with stock alloys and 31s my front tires rubbed at full lock. I bought new rims with more offset so they don't rub anymore. I also installed a 2" coil spring lift after.

Hey, welcome to the board. I figured I'd chime in as well as I just put 31s on my 04 TJ. I have the factory 15x8 wheels and don't experience any of the problems at full lock that derrelw did. I got the Goodyear MT/Rs.
Oh and just a point of interest. My speedometer is more accurate now with the larger tires than with the stock 30s according to my GPS.
you only think that LOL I did it and found out the hard way that I was 8 mph over what I thought I was. I had cruise set at 70 and clocked at 78 UGH that was my Christmas presant from South GA Sherrifs Office.
go with the 2" either way .. gives it a lot better stance if you throw in some rims with the right offset .. cant beat the mickey thompsons for about $100 a piece
