3 inch is all your gonna be able to do with out getting into a bunch of other stuff.
I have 3inch ome heavy kit , I use 265/75/16 tire on stock wheel
285 gonna push to close to upper control arm when you air down for 4 wheelin... Just me ....Tire size has never been the reason I get stuck .. high center etc . pick a good line and take your time and wheel with experienced wheelers and you ll be amazed where you can go .
