If you’re living in an area that typically gets heavier / colder winters you should consider investing in winter tyres or snow socks.
WINTER TYRES
Winter tyres prevent accidents and give much better grip on the road in icy / snowy conditions. Many manufacturers suggest that winter tyres will perform better than conventional tyres once the temperature drops below 7 degrees Celsius, and that even at low speeds of around 30mph you’re stopping distance is reduced by about 22%.
SNOW SOCKS
Snow socks are typically much cheaper and can be a very good alternative to winter tyres. There are some drawbacks in that your maximum speed should not exceed 30mph and they will be damaged by driving at higher speeds on tarmac roads. That said, you should not be driving at high speeds on icy or snowy roads in the first place. They are also much easier to fit and remove.
