Unlike other countries such as those in Scandinavia, nothing about our climate, is guaranteed. We can end up with a mild winter, where to a be fair a summer tyre will get you through the winter. Or it can go pear shaped, and a summer tyre is useless.
I run my winter tyres when the average temperature drops below 7°C. Online data is widely available. This example is for Fife. Its reassuring to know that I've got rubber appropriate for the conditions and also should the, quick everybody run out and buy 27 pints of milk and 70 loaves of bread, for the 2 days of Daily Express apocalyptic end of the world frost, then I'll be able to get out of Tescos car park ok. As long as happens between end of November and the middle of April.
