I have a 2009 PW and just switched tires to Yokohama AT-S in a 315 70 17 size and D rated. My BFG tires were not worn out but I was contemplating getting new tires because I had slight DW. I wanted the Toyo MTs in an E rating but just could not pull the trigger on the purchase at that price.
The Yokohama AT-S tires have way better dry and wet weather traction when compared to my BFG AT tire. The ride is great and at 40 PSI front and 35 PSI rear I still do not get even a hint that it wants to go into a DW condition. The truck from new never felt very good over choppy bumps and always seemed to continue even after the bumps in the road were gone. Not any more so draw whatever conclusion you want but I'm convinced the BFG AT is susceptible to DW at the best and causes it at worst you make the call.
I have run only BFG on our YJ, XJ and our latest WJ with good if not excelent results. On my PW they suck beyond belief!
