Any normal tyre doesn't work properly below 7 Degrees, But I have never used any form of snow tyre on any car I have had, and didn't need too, winter tyres is/are a marketing gimmick the same as Christmas and Easter, all you really need to do is adjust your driving style to the weather conditions and you'll be good, easy really.

Well said - worth some rep.

Have a trusty mate who works for a well known tyre/exhaust company ... and his words are :quote there are some right easy sales out there that spend dosh on "winter tyres" for what reason !! ... I have always gone bye his advice on wheels and tyres and so far has always come up trumps ... if only I could get it to moove ...

Lot of money for what you'd actually need for a very limited period. I don't doubt they are a bit better in snow, I assume deeper tread pattern similar to off road, but ice is ice and nothing but spikes work on that.
