You may have a bad wheel bearing. Does the noise change when you turn right or left? It may also be bearings in the differential, which is more serious. Or it could be something as simple as rust on the brake rotor rubbing on the backing plate. It's tough to diagnose a noise through a computer, so you should get it checked out.
