The tires need to be made for where you wheel, are you a mud guy or a rock guy?
Mostly on/or mostly off road?
Care about noise or handling?
Etc.
So - Tell us, and we can make rec.
(W/o knowing, Thorn's are a waste no matter what you wheel.)
If you just want bigger tires, a 2" BL is the way to go...no suspension issues, and minimal change to center of gravity, etc. (A 2" BL lets the tires go up about 4" diameter with the same room)
A Tbar crank pre-droops the tires, you can get about 1.5" that way...which you can match out back w/a 3" lift shackle (~$50) or an AAL (Another 1.5" & an other $100 or so)
You'll also need an alignment after a tbar lift.
