I little update after driving 600 miles on my new F1 A/S IN THE RAIN.
My drive from Nashville to Kansas City had 90% rain.

- The ride is smoother than my OEM Mich Pilot Sport.
- Tires handle well at 110 mph on wet road and changing lanes in the rain.
- Tires handle great at 125 mph on damp road.
- Tire noise didn't seem to be any louder/quiet.

I never hydroplaned, though I didn't hit any "puddles". My little orange traction light never came on.

Hope this helps.
