The first suspect would probably be tire balance. A broken tire belt will also be felt at lower speeds. The people at tire and alignment shops are experts at finding the causes of noises and vibrations. They will inspect the steering and suspension systems, and "read" the tire wear patterns for clues. They will usually start with a test drive with you, then balance the tires if that appears to be appropriate.
