It seems as if there are a few threads going on about tires right now, and I thought would add my opinion. I am a firm believer in the ability and styling of the BFG M/T. Unfortunately, I have been through two sets and they have both done the same thing. They ride, perform, and look great for the first 25k but then they get a shake in them that will drive you crazy. I rotate every 5k and the wear looks normal on all 4, it even looks like I could get another 10k tops out of them-bringing total mileage to about 35k for a set. My pressures are 55psi front and 45 psi rear. The shake, I believe, is caused by them going out of round. I cannot find a complaint with the tires except for them becoming unbearable with good tread still left. I have been through 4 sets of the BFG A/T's on a Toyota with no problems. I am needing a new set of tires, but am reluctant to spend the $$$ on M/T K/M's if they do the same thing as the old M/T's. I am beginning to lean towards going back to the A/T KO's, has anyone else had their BFG M/T's do this?
