I have driven 3 winters in my 997 C2S. I have a set of OEM Turbo 19's with 235/33/19, 295/30/19 Pirelli Sotto Zero II snow tires. That car stays planted through every snow storm. It is my daily driver and most every other car I have sits. When my buddies see me pull up in my 911 over my H2 during a snow storm they laugh. It really is actually fun in the snow. A C4S should be a tank in the snow.

 

I have a C4S and live in Toronto. I also have rental properties in Northern Ontario (Sudbury & North Bay) and drive my car up there at least once a month all winter long, on my 3rd winter with this car and never had any problems.

Running Pirelli winters and the last me about two seasons, just put a fresh set on this winter, tire run great

The one thing i will add is I run 18's in the winter, i found they made a huge difference on ride quality.
