Default Strange & Scary Sounds From Rear Wheel

Wish it was Halloween and I don't have a problem. I've got 6,700 miles on this baby. I went on a 200 mile trip today and about mile 50 I noticed a "wheel" noise. It is not related to engine speed, but vehicle speed. At speeds below 5 MPH there is no noise I can hear. Then about 10 MPH it becomes noticeable. Above 50 MPH the other noises cover over the sound. It is a frequency of a flat spot on the tire. The sound is like a scraping sound, oh like a disk rotor that is scraping on one side. Maybe the Cobra does slow down slightly, but not noticeably. You hear the sound much more than the sense the Cobra is slowing down. I looked a little underneath and only found some fine white dust at the bottom of the coil-over spring. Nothing seemed any hotter on one side or the other. The brakes are smooth and even and don't change the sound. Any guesses? I wana get 'er fixed ASAP as a lot happening in the NW in August!
