Tyres, explained for UK drivers
All-Season or Winter Tyres for UK Driving
7 November 2026
For most UK drivers, the choice between all-season or winter tyres comes down to where you live and how you drive in the colder months. Winter tyres give the most grip in snow, ice and cold, while all-season tyres are a year-round compromise you don't need to swap. Neither is a legal requirement in the UK. Here's how to choose all-season or winter tyres for UK driving.
Quick answer: Winter tyres suit drivers who regularly face snow, ice or very cold mornings, and who are happy to swap tyres twice a year. All-season tyres suit drivers who want better winter grip than summer tyres without changing them. There's no legal requirement to fit either in the UK.
Key Takeaways
You don't have to fit winter or all-season tyres in the UK.
Winter tyres use softer rubber and deeper, heavily siped tread for cold, wet, snowy and icy roads.
All-season tyres are a compromise designed to cope with all four seasons.
The mountain and snowflake symbol (3PMSF) shows a tyre has passed a standard snow test.
Some European countries have winter tyre rules, so check before you drive abroad.
Summer, all-season and winter tyres
Most cars in the UK leave the factory on summer tyres. They give good grip and handling on warm, dry and wet roads, but the rubber hardens in the cold and the tread isn't designed for snow.
Winter tyres use a softer rubber that stays flexible in the cold, with deeper tread and lots of small slits, called sipes, that help grip on snow and ice. Tyre makers commonly describe them as performing best in cold conditions, often quoting around 7°C as the point below which they have the advantage.
All-season tyres sit in between. They're designed to cope with summer and winter conditions, so you can leave them on all year.
Summer | All-season | Winter | |
|---|---|---|---|
Best for | Warm, dry and wet roads | Mixed UK conditions all year | Cold, snow and ice |
Swap twice a year? | No | No | Yes, unless fitted all year |
Snow grip | Poor | Better | Best |
Look for | No winter marking | Often 3PMSF | 3PMSF |
What the markings mean
M+S means mud and snow. The tyre maker chooses to apply it, and it doesn't on its own prove snow performance.
The three-peak mountain and snowflake (3PMSF) shows the tyre has passed a standard snow performance test. Most winter tyres and many all-season tyres carry it.
Our guide to reading a tyre's sidewall explains the other markings too.
Which suits you?
Winter tyres may suit you if
You live in an area that regularly gets snow or ice, such as higher or rural parts of the UK.
You have to travel whatever the weather, for example for work or care duties.
You have space to store a second set of tyres, ideally on their own wheels.
All-season tyres may suit you if
Most of your driving is on main roads in milder parts of the country.
You want better grip in cold weather without swapping tyres twice a year.
You'd rather keep one set of tyres for the whole year.
Rules, insurance and practical points
Whatever you choose, the legal rules are the same: at least 1.6mm of tread across the central three-quarters of a car tyre, and no cuts, bulges or exposed cords. Our guide to UK tyre law covers them all.
Your tyres should meet the size, load and speed ratings your car's maker specifies. Some winter tyres have a lower speed rating than the summer tyres they replace, so check the handbook and ask your fitter.
If you're not sure whether your insurer treats a change of tyre type as a modification, ask them before you swap.
Cold weather also lowers tyre pressures, so check them more often in winter. Our guide to TPMS warning lights explains why the warning light often comes on during the first cold snap.
Driving abroad
Some European countries have rules about winter tyres or snow chains in certain conditions or at certain times of year. If you're taking a car abroad in winter, check the rules for every country on your route before you go.
Are winter tyres a legal requirement in the UK?
No. You can fit winter tyres if you want to, but the UK doesn't require them.
Can I use winter tyres all year round?
You can, but the softer rubber tends to wear faster in warm weather, and summer or all-season tyres usually handle better on warm roads.
Should I fit winter tyres to all four wheels?
Fitting them to all four wheels keeps the grip balanced front and rear, so that's the usual advice from tyre makers.
Do all-season tyres work in snow?
Many do better than summer tyres, especially those with the 3PMSF symbol, but a dedicated winter tyre usually grips best in snow and ice.
Before the cold weather arrives, check the tread on your current set using our tread depth guide, and talk to a tyre fitter about which option fits the way you drive.
