33's would probably rub a little..

 

So 31s without a lift maybe?

 

If you put 2" spacers and shackles/blocks then you can clear 31s maybee 32s or 33s if you do some smart fender trimming.

 

On the chip i wana note that if u get a diablo chip its 299 u can change ur map o get better mpg then to pay it off do it to other cars for some cash back

 

im lookin into that jeep fashpaq from Superchips. i like it. i might have to try it. 31's would probably clear maybe a little rub but i dont think it would be to bad. My buddie put 31's on his stock wrangler and you have to crank the wheel completely to get them to rub..

 

When I first had my 93 zj it had 31s and they fit fine but would rub when turned really hard and I little on the wheel well but it's fine

 

31's will rub like crazy, I had to trim the bumper after a 2" BB (with upcountry at that) and 31's, if it was stock it would rub BAD.

and I have one of the higher sitting upcountry ZJ's I have seen so no spring sag

 

It won't rub bad you could trim your fenders but on my zj it was fine no matter what else people thought

 

if you have to trim your fenders, that means it rubs pretty bad. if it didnt rub bad, you wouldnt have to trim your fenders.....

 

I'm telling you it was fine and I didnt have to trim my fenders I'm just saying that he could and if you don't think that this is possible well I've seen it on my jeep and flexed it hard and it was fine
