Yeah, they feel like they are going to wash out under you when riding hard in corners. Takes a bit of time to get used to it. I'm thinking, considering and reconsidering... for now it's Michelin City in 35 mm up front, and CST slick in 35 mm rear. Might just leave it that way for some time, and see how that setup fares. I have more City tires in stock, but am really reluctant to try them again. Front did not blow off (at least not yet), so I kept it on. Time will tell how it behaves. Maybe it was only a fluke, but then this report of other riders having similar problems doesn't quite inspire confidence in that tire.
