Whenever a modest amount of snow falls in the UK and our motorways grind to a halt, it is never the weather that is to blame, but our lack of preparation.
In this comprehensive guide to preparing yourself and your car for the winter months, we’ll look closely at winter tyres and discuss whether or not they are worth the outlay, before considering every other aspect of driving during the cold season.
Winter tyres
Even as winter tyres become increasingly popular here in the UK, many drivers still misunderstand exactly what they are for and why they should be fitted in a country that rarely sees snow. The truth is, winter tyres are not only designed for snow and ice. They are also grippier and therefore safer than summer tyres in all weather conditions - even in the dry - so long as the ambient temperature is lower than 7deg Celsius.
What are winter tyres?
The most important thing to understand about winter tyres is that they are not ice tyres, or even snow tyres. They do not have metal studs of any sort poking out of the tread. Instead, winter tyres are simply designed to be used when temperatures are low and the roads are slippery. Of course, they are far more effective than summer tyres on snow and ice, but they will provide more grip and traction even on a bone dry surface just so long as the ambient temperature is less than 7deg Celsius. They are better at clearing standing water, too, so winter tyres are also safer than summer tyres when it’s raining.
Between the end of November and the start of March, then, winter tyres are almost certainly going to generate more grip than summer tyres.
How do winter tyres work?
Winter tyres are different from summer tyres in three specific ways. The first is that the tread pattern has many more grooves, or sipes, cut into it, which displace water and help the tyre to bite into snow and ice.
Secondly, winter tyres are made from a compound that has more silica in it, which means they stay soft and supple even in freezing temperatures. In very cold conditions, the rubber of a summer tyre becomes extremely rigid, meaning it slips across the surface of the road rather than clinging onto it.
Finally, a winter tyre’s rubber blocks are designed to vibrate when on the move, which means any snow they might have picked up will be shaken out. A summer tyre, meanwhile, will become clogged up with snow and ice and in effect become completely smooth and entirely useless.
Can you use winter tyres in summer?
There is no legal reason why you cannot use winter tyres in summer, but we certainly wouldn’t recommend it. In warm weather, winter tyres will wear out much more quickly than summer tyres, hitting you where it really hurts - the wallet.

Autocar quite often concentrates on ultimate performance. It makes for good reading, even if most of us will rarely demand such performance from our cars. It's what sells Land Rovers - it's nice to know it can do it.
This piece on winter tyres falls exactly into that mould. It has appeared before so I suppose its really a remould, but it argues for ultimate performance in Winter. Most people don't want that. Most people can't or don't want to afford the investment of £400-500 in a second set of tyres. Plus a £60 fee twice a year to take them on and off. Plus a £40 fee each year to store the other set. Most people will be safe enough using their normal rubber with a safe tread depth and driving more carefully in extreme conditions. Those of us that live in the Northern hills may find that All Season tyres give that extra safety margin to get home or get somewhere vital, particulary in snowy conditions. I have used all three types and now fit All Season tyres as normal. I don't drive to need ultimate grip in the summer and they are better in all conditions in the winter without the huge expense of snow tyres (as I will continue to think of them).
Totally uneccessary expense. They are just a recent gimmick. All that is needed is for the driver to drive according to the conditions. I used to travel over thirty thousand miles a year in all sorts of adverse conditions. If drivers take note of the conditions then do not buy them
I've often considered getting winter tyres, but couldn't justify the outlay, until it's explained that although you are paying for two sets of tyres (and probably a set of wheels) they obviously last twice as long, so make economic sense if you plan on keeping the car for three or four years. Having said that i' ve never "needed" them and you still can't really travel if the car in front hasn't got them.
