I thought it was my tires, which were close to needing replacement. After installing the new tires the noise is still there, and they are inflated to 30psi, which Honda recommends. It started a few weeks ago, and it came on fairly quicky. Although I could be somewhat oblivious since I usually have the stereo up fairly loud.

Mine's a '98 Accord with 138K miles. The rear wheel bearings were done 15-20K ago, but I don't believe the fronts were ever done. I can't really pinpoint which end the noise is coming from because it just it completely fills the cabin.

I'll have the wheel bearings checked out -- does anybody have any other ideas?
