My 2 cents of speculation would be Michelin, Pirelli, Dunlops. I'm a Trofeo R fan - will be running them 2 sets of them in the early part of this season as the mornings are still cold and I've got to work off winter rust with a new car. You give up some durability, Dunlop R compounds are pretty average so far but they might have improved them for the RS.

Once you track on slicks or Hoosiers, R-comp tires are lame with much lower performance/grip levels. It's a joke that Porsche is marketing these as trackable cars, yet limit the tires to overpriced Michelin/Pirelli street tires. I don't care what people say, these are not true track tires.
