Manufacturers are now producing a hybrid all-season tyre. They can be left on the car all year round, but on the whole, you don’t get the performance of an actual summer tyre. You also have snow socks and snow chains; these are excellent for getting you out of an unexpected situation, for example waking up to find 5cm of snow on your drive or if you have to go on side-roads that haven’t been treated. But be aware they’re not designed for prolonged use, once you are on treated roads they should be removed.
