The St. Petersburg suburbs are where I make my home. In the winter, I drive on the highway every day. The tires have great stopping power and maneuverability on any terrain. They make traveling at speeds of over 130 kilometers per hour possible in the winter. When 40 or 50 automobiles crashed into each other on the Kievskoye highway in February 2022, I was able to slow down for 100 to 150 meters on the ice before losing control (although at the end I had already put out the fire with the help of a snowdrift near the bump stop on the left). I have purchased winter tires from Pirelli before. Strongly suggest.
