Since I had the F1s all of last summer and winter, and into the first summer with the Michelins, my opinion is... well, my opinion Note that I am only familiar with these All Season tires, not having had the luxury of keeping different tires for different seasons.

It's hard to fairly compare grip between F1s which have gone 28k, and Michelins which have 2k only. Having said that, I use less brake when making tight corners because the car feels sturdier and more glued to the ground. In the little rain we had had in the past few months, the grip has remained shockingly good up and down steep slopes and tight curves. It is said that All Season tires compromise much to fit all seasons. I have yet to notice any disadvantage or performance hit.

Just a small observation: the vote is for the All Season model of the GoodYear F1 I believe. Not the Assymetrical, which is a Summer tire. Hope this is clear to all... Hard to believe such contrasting opinions of the GoodYear F1 A/S tires...
