Good idea to get 33's?

So I have a 98 TJ with a 4inch lift and 31s on it. It has the 2.5 in it and I will be needing new tires soon but want to go bigger, can I run 33's without major loss engine wise? It will not be on the highway\freeway. It only runs on the street and trails, advice please

On the trails and on the street you may be ok without regearing, It seems I've read its mostly problems in fifth gear. However, since you have an se you likely have the d35 which most wouldn't recommend running 33s with, but if you wheel carefully you could probably get away with it.

The consensus is that doing 33's with a 2.5, with stock gearing and a D35 is ill advised. You CAN do it, but you won't be happy with it.

What transmission does it have? With the 2.5L and open diffs you're in no real danger of snapping the D35. One of my god friends runs 33s on his 4.0L but he has 3.07s so not as much torque is applied to the shafts. That said, as long as you're not trying to do burnouts or anything, you most likely won't break it. It won't be too fun to drive though. The 2.5L is under powered as is without adding larger tires. That said, lots of people do it. Does another jeeper you know have 33s he'd let you borrow for an hour or two to see what it would be like driving it?

I have a 2.4 with 33" tires and it runs perfect. Of course I regeared to 4.88 with a Ford 8.8 swap. Get a better axle before getting the tires.
