I am on my second set of BFG AT's and I really like them. Got 60K+ on the first set, 4 tires, rotating every 6K. I have 52. 8K on my second set, this time rotation 6 tires (don't ask) and I will get another 40K out of them. Run 50 lb front/40 lb rear when empty; 50/50 with a load. I don't tow but do a lot of 'fire road' and trail running with a 1000lbs of camping/prospecting/spares in the bed. When air'd down (15 lbs front/rear) the BFG AT's provide very good off road traction. I know the BFG's have been blamed for contributing to 'death wabble' but I think that would have to be on a heavly loaded truck.
I'm so old I can remember when, in high school, if you got 10K miles on a set of tires you were doing well! I even remember getting flat tires... anyone had one of those lately? Today, we can get 60K on a set of 4 on a very heavy truck! Life is good!
