Basically which would be better/get me further offroad? I was finallizing my plans to run 33s, and would end up costing me around $1300, plus money back from selling my 17s within 31x10.5 AT2's. Then realized a locker or more likely LSD in the rear would be less/same price.
We play in the mud where I live so I feel like the MTs would be better for when you bog down, as the AT2s turn into slicks and its hard to judge how both rear wheels spinning would help in that situation.
Have a 2004 sport, stock D44 rear with 3.73s, I6. BB, 1.25" BL, 1"mml, and soon to be zj/3 inch lift springs up front
The issue with doing a locker before tires is if you plan on regearing for tire sixe XX then you'll need to pull the locker back out when you do the gears. IMO Tires first then a locker and gears together and then the winch. I still dont have a winch on my YJ and I'm putting a pair of 60s under it. Not having one has never held me back.
Though when I read locker vs. lsd, it seems an lsd would be better for my location with driving in winter snow and all. Though I'm not too worried. If i could handle it in a mazda 3 I feel like I would be good trying to feel out full time locker.
