Yes tires can become 'cupped' where each little segment of the tread is curved a bit.
It happens from really endless hours on a freeway, driving on cruise control IMO.
The curve in the tread makes noise.
You can: Rotate the tires. Increase the air pressure..
Turn up the radio..
buy new tires..
Another way is to drive around a LOT* of corners fast.. that will alter the tread blocks some and stop the whine.
*thousands... well at least hundreds.. LOL
If you tend to drive in the city a lot, the problem may wear away.
If all YOU do is straight freeway.. then you are out of luck. (though rotating them might help.)
