I switched from Yokohama slicks to Michelin N1's last weekend at Miller. The car is set up to have a very slight push and that has worked well for me all year. We reduced the camber a small amount after doing temps and pressures and initially the tires worked very well. After the 3rd heat cycle (#3 being a 1 hour enduro) the car started to push a lot more and braking distances grew considerably longer. No changes mechanically, the tires...especially the fronts, got really greasy.
Is this a typical Michelin issue???
Or is it my problem as in too much sliding around and over heating the tires??

They should be fine after 3 heat cycles in my experience.

+1.... My experience with Michellin's is that they want more camber than the Yokes. I run the Yokes at -3.5/-3.0 while I ran the Blues as much as -4.5/-4.0.

With respect to pushing, I've found ride height and more specifically, rake to play a instrumental role in how these cars turn-in and handle in general. Do you know your ride height specs?

PS: Was it windy at Miller and were there a lot of 'offs'. I've run there 4 times and have always encountered sand on the track which makes conditions slippery. Its such a smooth track, any surface material really messes with grip...

In my limited experience, with the same setup, just changing tires:
Yoko = overstereer
Michelin = understeer
