Noise coming from the tire left rear tire at a moving speed about 5 miles or more

I had this problem two years ago. While the car was moving slow I could here a problem with the rear tire. The reason was that I had replaced the rear tire with a new one and the tires did not match. The computer was trying to compensate for the miss match I took it to the dealership and they reprogrammed the computer at no cost and all is well.

See if the tire is if good condition .How long have you use this tire,some when using it too long it loses it's shape,that why it make that noise,it loses the circular shape,this is one possibility,second possibility is you near two check the wheel bearing may be it need to be lubricate with grease.Hope that clear your mind and help you.
