All season Pirelli P-Zero Nero M + S here in Chicago for the past 2 winters with no trouble. I drive it year round in all types of weather...I just make sure not to venture out when the snow is REALLY coming down. This usually happens at night and I'm already home from work. The roads in Chicago are cleared off very well and for the most part very quickly. Weather reports seem to be much better in predicting snow and this makes it a bit easier to plan my next day!
