While driving 70 miles per hr on the highway a loud noise and slight vibration was felt. After slowing down, the noise was not as loud and the vibration was less. On exiting the highway onto a busy road driving no more than 45 to 50 mile per hour the noise was not noticeable and the vibration seemed to be gone. On getting out of the car and looking at all four tires it was determined that the noise and vibration was coming from the highway surface. On pulling out of the garage the next morning the noise was back and the vibration was very noticeable. Road service was called to check to see if their was a flat tire or a problem with the wheel lugs. On arrival the service technician drove the car and discovered the back right tire had separated in several places causing the sound and the vibration. His statement was "someone up there must love you", this would have killed you if you had continued to drive on it. The tire was removed and will be taken back to the place of purchase. This is a Firestone tire purchased 11/27/2010 31.
