I'am bit curious. Here in Sweden you have to have snow/winter tires from 1 december - 31 march or earlier/longer if the temperature is below 0 degrees. We have two different types of wintertires, the european one without spikes and the more common with spikes, about 70% of Sweds drives with spikes. My car arrives in January and I have ordered tires with spikes, the besttires when you want to drift and use the quattro on frozen lakes! How is it in other European countries like the UK and so on?
