I have a 2005 with a similar problem. I would describe the noise more like a tank than a train. Sonds like you have a real set of knobby tires but in fact you can hear verry little of that noise out the window. When I get up over 55 you can feel it start thumping through the floor and pedals. Really odd. I was going to guess it to be a wheelbearing or something but is missing classic simptoms (like noticable during cornering etc.) Would really like to know if someone has figured this out before I start my exploratory surgery.
