I thought vibration, shakes, out of round are features of BFGs! Costco tried to tell me it's normal. It would start about 15-20K miles, I would take in for balancing once a month, they would get tired of that, and tell me that my rims were bent because the tires aren't running true. Wrong answer! Then they would say that all big offroad tires do that and if I am going to run them get used to it. Wrong answer! They wound up replacing them twice, it's nice to get new tires every two years, but not worth the hassle. This was on my '90 4Runner, I had really bad luck with them, don't know if it was the tire/truck combo, my driving, the hot Arizona summers, but it turned me off on BFGs.
