You are one of the lucky ones then. In my case, and many other postings on here many also concluded it was not the tires. In my case, they replaced all four tires. It still vibrated. Then they Road forced and had to replace one of the new ones they just installed. Yes, when they replaced and RFB's the tires, the vibration was better, but it time, the vibration came back. I still have a vibrator. Been a GM guy all me life, but I think I may need to bend over and get a Ford. I cringe when I say this!
