Here is a thought: The tread pattern on the Avon Storm has a slight variation in the spacing of the tread grooves. This is designed so that there will be no speed at which a resonant vibration can occur.
The ST1300 OEM Dunlop tires have a uniform spacing of the tread groove pattern, and at about 50mph, the frequency of the grooves hitting the pavement is also the resonant frequency of the front fender, and it will "howl."
While the non-uniform spacing of the Avon Storm ST will not excite a resonant frequency in the front fender, there is wavering input to the bike once per tire revolution and it can feel a little like a very mild "head shake" at a certain speed. If you don't wear earplugs, and are on a good smooth pavement, you can hear the tread pattern noise wavering slightly.
