I'm another cold weather tyre advocate I'm afraid.
Rear wheel drive cars with high performance summer tyres are a bad idea in the snow and ice. I've had lots and its not fun.
Buy cold weather tyres and forget about it.
Leave the car at home and walk and pray you won't get caught out and about during a snowfall.
My personal opinion is that we should all be forced in the uk to have cold weather tyres fitted just like our European neighbours. There really is no constructive argument that can be made not to use the correct equipment at the correct time .
