Mikla:

Cups are great when warm. I was talking with a Porsche service guy about the lack of "winter" tires for the GT4. For winter I mean sport tires like PZero (no real M+S). My winter rides on the Spanish mountain roads with temperatures of 10-12 degrees are not suited for the Cups.

Listen, I had traction issues with my PZero road tires at around 12°C (yesterday in Bavaria) and my car has AWD, so... Tire temperatures around 30°C or lower, not exactly OK for them. I need at least 50°C for them to be really sticky. Cup tires need even higher temps, I think 60°C upwards are great...(Trofeo loves around 70°C and I think the Cup 2 is between 60 and 70...not really sure). They are OK up to 50°C or so but under...not so much. Cold and rain? Deadly. Smiley
