We totally caved in today. For a couple of weeks now, we've had an increasingly hard time of traversing the ~1.5 slippery and icy kilometers from the main road to our house. There are three major 90+ degree turns and one speed bump to traverse - all while climbing pretty steeply - before we get to the final plain and turn down to our place. Ever since we moved to Trondheim, we've rolled with regular snow tires, but today we had a hard time getting up our own driveway, so we loaded up the car with our summer tires (which were due for replacement come Spring anyway) and left for getting proper snow tires. With spikes this time - the biggest and most pointy we could find.
