I recently bought a new 2006 Passat. I only have one complaint. When driving on a smooth highway there is no road noise inside the car. But when I drive on rough (the old tar and crushed rock patch work stuff) I get so much road noise inside the car I can't hear the radio. I have the Goodyear Eagles on the car. Anyone have the same problem? Is it the tires or a trait of the Passat? Thanks
