I have had several sets of BFG AT's on differant trucks all with straight axle fronts, dodge and F350's. I have gotten 82,000 out of the best set and 65,000 plus out of all. I currently have a set on my F350 now.
I have a set of E range 285 16 duratracs on the Rubicon right now, their is 12,000 miles on them and they are half worn out. I know I beat the shit out of them and spin them on stuff, so it is not a fair comparison. The Duratracs have been good on every thing except mud, they will not clean out.
The TA's are by no means a mud tire, but they clean out better than the dura tracs.
