I think there are enough "show" jeeps already, where tire size seems to be the biggest concern.
I say wait til you can afford to put them under something wortwhile.
i am already pushing the 34's. and no, if youve seen my jeep, and know me, youd know im not about cosmetics. I am so under geared right now its fricken rediculous. but at the same time, im not getting traction in 4x in the front open diff... so i dont know whether gearing is a bigger advantage than up front traction... if i dump a cheap locker in for now, then i'd have to ditch it later to regear, or ditch the gears and locker later to get a dependable diff in the rear w/ proper gearing (5.13+)... or wheel it now with sh*t gears and no front traction till i get new f&r diffs... which might take some time, and more time is less fun.
i know this is more a personal choice, but i everything is vetoing everything to me, so i thought id throw it to the jeep masses and maybe get something to tip me into one direction or another... might even do something completely different, but it's just talk over a campfire and some beers.
just shooting the sh*t.
