I can't even hear my Michelin Defenders, except on places where the Highway Dept. of different States have done test patches, using different finishes on the Concrete Road.
There is one such test patch on Interstate 10, east bound, about 20 miles from El Paso.
When i drive on that test patch, it sounds like a knobby off road tire is driving right next to me, surprises me every time.
There is another place in San Diego, on South Bound 805, EXIT 18, Murray Ridge Road / Phyllis Place
There is a series of test patches in the concrete, my tires make noise there too
The Michelins are also great at gripping the road, even when it is damp
