Which leads me to a question I have asked myself of late. . . all Scandi countries (& Germany ) recommend, or mandate by law , the fitting of Winter tyres on cars , yet. . . .I use exactly the same tyres to land a 737 in Malaga in Summer @ 37c as I do to (try to ) land one in February in Tromso with braking action that is (as advised by the Norwegian CAA ) at best "unreliable" am I missing something here
