Well, after what has turned out to be a horrific winter here in Chicago (and everywhere), I have to say that I am VERY happy with my 19" Sottozero's. I mounted these 19's on a set of 997.1 Turbo OEM rims, and they have performed above and beyond in these ridiculous wintry conditons. I commute into the City ~40 miles a day in my C4S Cab as my DD, and this car on these tires is an absolute beast in the cold, ice, snow and sleet that we've been having this winter.

And I have to say that I have thoroughly enjoyed blowing past all the SUV's on AS tires on the highway as they have struggled in these conditions!

All in, I would rate these Pirelli's with 2 thumbs up in what has been a pretty extreme winter this year
