We had a set of AT's on our shop truck and they were some of the worst tires Ive seen. 2 of the 4 had to be sent back right away due to being out of round and even the "acceptable" tires always had vibration issues. We swapped tires to different trucks and the vibration always followed the tires not to mention poor traction. I would have a very hard time ever spending money on Falken tires after seeing the poor quality control.
