I ahve checked the other posts by doing a search and all problems sound similar, but am not sure if my is the same. So here goes:

Last week changed back to "winter wheels" which are the stock SS wheels and Bridgestone Blizzaks and as I coast or come to a stop I get a rubbing noise like the brakes are rubbing, but unevenly. It happens as I am rolling but as soon as I hit the gas or brakes it stops, but gets louder the slower I go. The brakes on both fronts do not seem to be rubbing, and cannot see anywhere else where there could be rubbing going on. Can anyone tell me what this is?

 

Check the torque on the lug nuts, could be loose. Also try cleaning the rotors, maybe got them dirty or greasy when changing wheels.
