I am running 31's on my 03 with no lift with after market wheels and have no rubbing issues so far and I have been out on the trails several times. Welcome to the club. Take your time and go wheeling with some groups and see what you want to do and it will also give you a chance to see other jeeps. You can spend a ton of money on the obsession so take your time so maybe you don't have to spend money on the same thing. A 2" lift maybe all you will ever need but you may want taller. Also bigger tires are going to effect your gearing. My 31's with 3.07 gearing gets by on the road though 5th gear is basically useless, In 4Low I have been doing fine for the trails that I go on. I want a lift but then I need to go to bigger tires but before I do that I need to deal with the gearing first.
