The sound associated with noisy tires and bearing is very simmilar. They both have a similar deep moaning sound. At first I thought it was my tires due to it being half way worn down and my car only had about 35,000 on it so I did not think my bearing would already be going bad. One thing that was apparent is the noise was consistent on any surface and got louder as I swerve side to side. Tire noise will often vary depending on the road surface. Also tire noise can be alterred depending on the tire pressure. Kumho's I know does tend to get noisy especially when you are down to less than 50% tread life (this is from my experience with my old car GTI)

The other method about jacking the car up and feeling for play side to side on the wheel only works when the bearing is really worn, In my case I tried this test and could not feel and play. Also healpfull is having the top up when trying the swerving test, it helps you better hear the moaning noise. I also remember reading on Renntech that it was common for bearing on driver side to go out...
