On a 4 cylinder TJ the general consensus is that you shouldn’t go over 33”. Not only that, but if you go that big, you’ll need to gear it really deep (5.13 usually) in order for it not to suck.
The 4 cylinder sucks as it it on the highway, throwing 33s or 35s on it is going to make it worse. If it were me, I would stick with 31s.
