Winter Tires on a Supercar?

Winter tires help cars stay mobile in wintery and snowy conditions, but at what price?

Due to the siping needed for the winter tires to work in snow and ice, a winter tire often makes a cars steering feel light and vague, which is the last thing you want on a supercar like the Porsche 992 911 Carrera 2S. Modern ultra high performance winter tires promise to retain steering and handling feel, while allowing the car to be used in the snow, and the new Michelin Pilot Alpin 5 is one of the best at this.

To find out exactly how good they are, I drive a Porsche 992 911 Carrera 2S from England, to the Swiss part of the Alps, and document the journey including steering feel, snow and ice performance, handling, comfort, noise etc.
