Hey deepblueQ, I gave you a belated thanks. All you have to do is listen to a few episodes of Car Talk to see how difficult it is to describe car noises. It was a hum/rumble with a vibrato
that changed in frequency when the car speed changed. That's the best I can do.
The majority of the noise did in fact come from the worn tires. When I first replaced the tires, I thought the problem was solved. I had to find a smooth road, turn off the music and let the car coast to still hear the noise (and my hearing is still pretty decent). I'm guessing the original alignment issue and this problem was from a related event that happened prior to me getting the vehicle. It was new, but had 112 miles on it. The service advisor told me he thought a flat spot developed in the bearings from the car sitting too long from its manufacture date (Nov 2010) until I bought it (Aug 2011). Sounds absurd to me. Personally, I think it got a rough test drive that just left no visible damage.
