We had snow - one night of it. The roads were a bit slushy in the morning, but that's all.
Kinda disappointed, because the Tiguan had a set of well used Bridgestone ditchfinders fitted when I bought it, so I replaced them with four Cross Climate+. The Michelins are excellent in the wet, that much I know, and are supposed to be pretty decent in the snow, although I doubt I'll find out down here.
