dude I have never heard of that one... I think is a tire thing,,, because things are new doesn`t mean that they are perfect,,,don`t believe me, ask someone that bought a new car and had to go back to the dealer several times for several problems, that "Has" been known to happen, those tires might be defective from the manufacturer, I would go back to the tire folks & tell them about the vibration you are experiencing..
