Minnesota driver. Shocked at how a change of tires can so drastically affect a cars handling, road noise, and stability. Had these for a week and my car feels like a totally, completely, different car. Background: bad previous tires (admittedly Hankook Icebear winter tires driven all year), or great current tires (Michelin Pilot Super Sport 18 245/45), the difference is astounding; incredible grip, very quiet, surprisingly smooth and creamy ride, and much less harshness from the suspension. Love these tires so far and am beginning to think there's a reason that these tires seem to be the benchmark for summer performance tires. WOW!
