What kind of road tyres should I go for winter commuting? I currently have kevlar vittorio rubbino tyres on my road bike, but they don't have enough grip for the oncoming uk winter conditions. What level of tyre tread do I need for road commuting on uk winter roads and any recommendations welcome. I would still like to maintain a low weight and good rolling resistance.
I used Swalbe Marathon's last year without too many problems. As has been previously said, the narrow (25mm) tyres do help cut through snow, but when you are on ice nothing is very good.

I liked Continental Top Tourers previously.
