Welcome to the forums, I think you will fit right in here.
Studded tires are great when you need them. I am guessing that Norway is one of those places that you are likely to need them. I sure do here in Saskatchewan (Canada)
Only problem is, studded tires are expensive and of limited selection. You could make your own with some basic tools. I wrote a tutorial here for studding tires but unfortunately the pictures disappeared with our gallery.
