Allegedly... it goes away again at 85mph and stays quiet until 110, but that's speculation on my part. Hopefully the hum will go away as the tire breaks in. All that said, i'd recommend the switch. Also pieced together the 19in space saver spare kit for piece of mind.
Good observation. It does go away after 1k miles for me.
