2005 Acura TL vibration

I just bought 05 Manw/Navi and high perfomance tire (Bridgestone Potenza). I feel a vibration when I am at high speeds of 60mph plus, I gave the car in for service and they balanced my wheels yet I still feel vibration. When I asked the service tech they advised me that all 04 05 tls have that problem! I just bought this car and I am really bummed out. Is anyone else having this problem and if so what have you done to fix it? Please need some advise and big time help

Thanks
