Winter tyres are not really suited to all year round use though – summer tyres will give better performance when temperatures are higher and roads dry – so you'll need two sets of tyres if you're going to choose specialist tyres for winter.
Why are winter tyres not compulsory here?
There are several practical and economic reasons:
- many parts of the country never or only rarely experience weather conditions that would justify use of winter tyres
- many drivers choose not to use the car when snow or ice are around
- assuming that the industry could supply tyres in sufficient volume, the overall cost would be prohibitive – estimated at £500/car x 30million cars = £15billion for wheels/tyres plus storage and fitting costs
Should you buy winter tyres?
Winter tyres make sense if you live in a remote area where winter conditions are likely to be worse for longer.
Elsewhere it may be harder to justify the cost, though this has to be a personal decision depending on the risk of bad weather, your confidence when driving and how much you have to drive when snow and ice are around.
Winter tyres are made by most of the main manufacturers. Some suppliers will provide these pre-fitted to a set of steel wheels too.
If changing from alloy wheels to steel wheels you may have to change the design of wheel nuts used too. Ask the wheel supplier or car manufacturer for advice.
Winter tyres must be fitted in sets of four. Fitting only one pair will affect the balance and stability of the car.
All Season Tyres
As an alternative you could consider buying 'All Season Tyres' which also have a high silica content for low temperature flexibility and a tread pattern somewhere between a normal summer tyre and an out-and-out winter tyre. Like all compromises they're unlikely to be as good as the best specialist tyre but can be expected to work better on wintry roads than a summer tyre and you will avoid the hassle and cost of swapping wheels/tyres twice a year.
Snow chains
If winter tyres are just too expensive you might consider carrying snow chains for use in an emergency.
Snow chains are of limited use in this country though because you can only use them where the road surface is covered in a protective layer of compacted snow/ice.
Snow chains can be awkward to fit and remove in the cold and when the wheel arches are packed with snow and your gloved hands are cold and wet.
Insurance implications - winter tyres
If you fit winter or all-season tyres in place of your standard 'summer' tyres there should be no need to tell your insurer – even though the speed index might be lower.
The lower speed index is still likely to exceed all national speed limits by a considerable margin – with the exception of some German autobahns – and is not checked as part of the passenger car MOT test.
If you follow the standard European practice of keeping two sets of wheels, one with winter tyres and one with summer tyres, then you shouldn't need to tell your insurer as long as the winter tyres are fitted to wheels of the correct specification.
- 'Correct specification' means that the wheel size – diameter, width and offset – conforms to the vehicle manufacturer's specifications.
- Check the handbook for details of wheel/tyre sizes suitable for your car and refer to the car manufacturer or dealer for further advice.
Over the winter of 2010/11 we did hear reports of some insurers increasing premiums or remarkably even refusing cover if winter tyres are fitted. As a result we recommend talking to your insurer if you are considering fitting winter tyres.
According to the Association of British Insurers (ABI)
If anything winter tyres should reduce the accident risk and, by implication, drivers who fit them are likely to be more risk-conscious too.
The major motor insurers have all confirmed that they would not class fitting winter tyres as a material modification and it would not impact on the premium. The one condition would be that they would expect such tyres to be fitted by reputable garage/dealer, in accordance with the motor manufacturer's specifications.
Some said that they would not require the policyholder to tell the insurer these tyres had been fitted, but the ABI's advice is to play safe and tell your insurer anyway.
Tread depth and pressure
Whatever tyres you fit they must have enough tread – at least 3mm is recommended for winter, and certainly no less than 2mm.
Check tyre pressures too but don't be tempted to try reducing pressure when there's snow and ice about – it doesn't help with grip and can affect handling.

The AA is supporting the Highways Agency's 'Make time for winter' campaign.
The HA has more than 500 winter service vehicles on standby but crews need time and space to get ahead of traffic and keep the network clear. You can help by planning your journey around the weather.
- Be informed - check traffic and weather
- Be prepared - check your vehicle and carry an emergency kit
- Be aware - winter teams need time and space to do their job
- Be wise - conditions may change, drive with care
