I think it all depends on where you will be driving. If you are going to be on the road more than off the road then the BFG's are the way to go. I ran BFG'S for years, but i have a 2 wheel drive, i loved the BFG'S,great tread ware, i had 295 50r 15's 10 in. Wide rotated them every 3 thousand miles, did alot of burnouts and still got almost 30 k miles out of them.
But if your going to be off road alot they're not to good in the mud. I've been out of the off road picture for quite some time now, i went from 8 inches of lift on my old 77 chevy to a 2/4 drop on my 92 chevy.
If off roading, you need tires that will clean themselves out when in the mud. Back when i had my 1980 Jeep cj7 it was in the mud 95% of the time, i ran Denman ground hogs, now that was a good mud tire, i rarely got that thing stuck in the mud, but they were real noisy on the highway.
So it all depends on what type of terrain you'll be driving the most!
Hope this helps.
