I may not have the perfect solution for you, but I had the same noise in a truck I own. A humming noise off the tires, but came and went on speed or bounce. Also, I noticed it got louder the hotter the tires got. Final solution to recovery: my driver's side tire, although it had plenty of tread and my truck was aligned correctly, had a cupping of the tread on the outside of the tire. Basically as the tire expanded and shrunk, the tire edge tread would rise and shrink, therefore, it was a cupping action against the pavement which created the humming noise. Once the tire was replaced, it's been as calm and quit as the morning son! BUT was very frustrating until I figured this out. Check your tires, mine was barely noticeable, but I could definitely hear it! Good luck, let me know what you find.
