I'm new to this forum, but my Norwegian is excellent (I am Norwegian...). I am very much into winter driving in the sense I have no choice. Where I live there can be 1 meter of snow overnight, there can be solid transparent ice on the roads for moths if nature is in the right mood. I own 3 miles of private narrow gravel road, which goes up and down and in sharp turns. Most winters I drive at least once in one foot of snow on my way home from work.
So, if you know a topic that could be of interest here in this forum , give us a tip. I can help you with the Norwegian. The latter article which you didn't how how related to the other three is just briefly describing how the tire tests are performed. No interesting details, really.
