I am in Chicago and the last few winters have been pretty harmless...But...I do have the Pirelli P-Zero Nero M+S tires and love them! They stay on my car year round and since I don't track or have many "twisty" roads here they are great year round. The Boxster does take a snow fall of +/- 4 inches from my personal experience as long as you take it easy as you should anyhow. Here's how I think about it--they were built in Europe where it snows, tested in the snow, are rear wheel drive like all BMW, Mercedes, and now lots of American cars and they are in the snow! So...No Problem!
