I have a '04 with 28,800 miles. I'm just starting to get the same hum. The dealer blamed the tires, just as I expected they would, but the complaint is registered. I have another question that relates to dealership service, but I'm not trying to hijack the thread.

I purchased my '04 used. When I tried to transfer the 7/70 warranty I was told that the original buyer did not buy it so I couldn't. Has anyone else heard this & is there a way to get it?
