I just bought (online) the new 21 inch Pirelli Sottozero 3 winter tires. Am I the first? Pirelli said they wouldn't come out before mid-november, but I saw them on stock (just 4 tires) at a big Dutch/German online tire shop and didn't hesitate. I should get the tires this week and will have them installed next month. They're pretty expensive at €465 each (ex. VAT), but there are advantages: - I can keep using the (beautiful) 21 inch rims in winter - I don't have to buy an extra set of rims - I don't have to buy an extra set of pressure sensors. Ofcourse 21 inch rims with winter tires are not the best choice in a harsh climate with lots of snow and ice, but our winters are not that long and severe. However, it does snow and freeze occassionaly, so I don't want to take any risks with summer tires in winter (in combination with the torque my P85 produces). I will rotate the tires when going from winter to summer tires and vice versa, hopefully prolonging the life of both sets.
