to check if you have a bad wheel bearing jack up the side you think it's on. once the wheel is off the ground, grab the wheel north and south and jiggle it. if there is play(movement) in the wheel then it's more than likely a bearing.
it's probably just your tires. i have the same problem. my bearings are new and i have that noise due to poor tire wear and being just plain poor. 
I'll check that out. And its kinda hard for me to hear the noise. I never really noticed it until he pointed it out to me. And recently I just changed my wheels/tires out, so I'll have to see if it was the tires or something. Thanks!
