Heisann!
It is amazing how big a difference the right tires make in the snow, the UK comes to a stop with a covering of snow, I've been driving on permafrost for the past 4 months! Where were you? West coast would be Stavanger/ Bergen area? I'm in Trondheim in mid Norway, its a lot drier here than the west coast, roads are not too bad condition, especially compared to Edinburgh!!
