I have a set of winter wheels and tyres - necessary when driving to some
countries in the winter. They are specifically designed to collect snow
in the sipes. Apparently the best thing to grip to snow is more snow. As
you say, they do very well in snow, but I don't have much experience of
driving with them on significant ice.
