As this will be my first winter in the Rocco, and as it seems we are destined for a lot more freezing temperatures and lots of snow, (sorry for being depressing

Last year where I live in the north west, we had a ton of snow and temperatures for a couple of weeks that dropped to -10° to -17°C. At the time I had a MK5 Golf 2.0 GT TDi, running 225x40x18 GoodYear Eagle F1 Assymetrical's (were brand new in November of last year so only had about 2k miles on them when the snow hit, so almost new). TBH, the Golf was crap in these conditions, and gave me more than one heart in the mouth moment. Even the slightest incline would defeat the Golf with the front wheels just spinning. My local council (Warrington), had obviously not heard of a thing called grit, so even some quite major "A" roads near me were death traps for quite a few weeks.
Now I appreciate that the F1's are not a winter tyre and that had a huge amount to do with it, but is the Rocco worse, and did anyone drive last year in these conditions on the Pirelli self sealers that I have on the Rocco ?
Anyone use a dedicated set of winter wheels and tyres, or is it a case of park the Rocco up and use public transport or Shank's pony ?
Cheers.
