As conditions dried out I was reminded of the fact that they were street tires, but I still walked away thoroughly impressed. Dry grip was just shy of some typical track-day tires out there, and it was really only under heavy braking that they may have fallen a bit short of R-compounds, but not by a huge amount.
Overall, the best street tires I've ever used, and apparently they should also offer a significant life expectancy considering what they're capable of. I have a feeling some of the newest street tires geared towards fast laps for the autocross crowd might have a bit more ultimate dry grip, but I doubt any of them can check off every box quite like these Michelins.
