Could be wheel bearings, could be choppy tire wear, could be a pulley. IF the noise changes when turning one way or the other, I would suspect bearings. IF the noise is present when at idle and pitch changes as accelerator is pressed, I would suspect a pulley.
If you run your hand around the tread of the tires, it should be smooth, not choppy or sawtoothed etc.
