I have a '00 GT with 18X9 wheels with Kumho tires.....have been getting excessive noise from the rear end. Sounds like tire noise.... the whoom-whoom-whoom as the the tires turn, but when I switch back to the factory tires, it's still there. I replaced both axle bearings, put synthetic oil in the diff, inspected the axles when there were out, all which were no help. Anyone else have this experience? The posi seems OK, I still get 2 turning on a burnout. I've had this car since new, and it has never been abused.....any suggestions would be appreciated.....

I get that same noise in my car. Just recently I did a little burnout and I only spun one tire.. What does that mean.. ?

Could be a warped rotor. The brake pads drag on the rotor in one place causing a noise like you describe.
