Fishtaker, not this time!
mskelly, do you have new springs? If I had tried to put 31's on my 91 YJ last year without new springs, the tires would hit the fenders! The bigger tires will surely add to the lift and clearance of the Jeep, but the clearance issue comes into play.... My daily driver is also my Jeep most of the time. I was thrilled to have the bones to put the 2.5 inch lift and a set of 31X10.50 spurs under there and it "looks" great and handles quite well. I don't do mountain hopping or swamp runs. Most of my trails have creeks to cross, a few rocky spots and lots of ruts and slick mud and plenty of steep angles and tight turns through the woods. This handles great on the road, on these logging "roads" as well as keeps the fuel bill down. Anything larger would kill me, anything smaller would look "cute"....
4x4david, If you want, you can put coil-over shocks on there or a slight body lift and get by with up to 31's without any trouble at all. You will more than likely want the spring lift pretty soon though. It may look a little silly for a little while, but I would put the money into a suspension lift first, then put the next batch of money in tires.....
kmoney, sure, you can do it, but you will most likely not have much clearance at all up in the fenders... You'd most likely have to be really careful when going over speed bumps and not be able to hit too many bumps or rocks or trees or whatever on a trail and surely not be able to hop the dunes....
sunder's about right, but the rubbing is damaging something that can be avoided... Just something to think about....
Putting the wider tires on will naturally be different than the stock sized tires.... Adjusting the bump stop will keep your tires from getting ground down by your springs. The hitting the flares/"plastic fender trim" won't be avoided unless you do something to get them higher or out of the way, like remove them, and then risk the tires sticking out past the fenders and getting a ticket in some states, or put a lift of some sort under it and get the trim up higher and away from the tires...
Summing up a bit, You really will have to consider what you want to get out of your Jeep. If you just want something for riding on flat stuff, then you can get away with a little grinding noise.... If you want to get ground clearance to actually clear obsticles that are in your way of getting to a scenic spot way up a canyon or top of a mountain or down in a valley at a lake or wherever, you will need to consider putting a little adjustment in your altitude.
