Key takeaways
- Stopping distances can be up to ten times longer on snow and ice, per the Highway Code — leave a far bigger gap.
- Tread and the right tyre compound matter most: cold-weather or all-season tyres grip far better below 7°C than summer tyres.
- Drive with gentle inputs — smooth acceleration, early braking and slow steering — to keep the tyres from breaking traction.
- Do not drop tyre pressures for snow; it is a myth and reduces overall grip and safety.
- If you are stuck or stranded, mobile help can reach you rather than risking driving on dangerous tyres.
Snow and ice strip away grip just when you need it most, and no driving technique fully compensates for the wrong tyres. The good news is that a sensible combination of suitable rubber and gentle inputs keeps most UK drivers moving safely through cold snaps. This guide explains how your tyres behave on snow and ice and how to drive to their strengths.
How much longer does it take to stop on ice?
Stopping distances can be up to ten times longer on snow and ice than on dry tarmac, according to the Highway Code (rule 126). That means the gap that keeps you safe at 30mph in the dry could be dangerously short on a frozen road. The single most effective response is simply leaving far more space and slowing down well in advance.
Tyres do the actual stopping, so their compound and tread depth decide how much of that distance you can claw back. Worn or summer-compound tyres lengthen it further still.
Which tyres grip best on snow and ice?
Cold-weather and all-season tyres grip far better than summer tyres once the temperature falls below about 7°C, because their softer compound stays flexible and their fine sipes bite into snow and ice. Look for the 3PMSF snowflake symbol, which means the tyre has passed a severe snow-grip test — the M+S marking alone is a weaker indicator.
Tread depth still matters hugely: aim for at least 3mm in winter. If you have not decided between tyre types, our guide to all-season vs summer vs winter tyres sets out the trade-offs, and preparing your tyres for winter covers the wider checklist.
How should you drive on snow and ice?
Drive as gently and smoothly as possible: everything you ask of the tyres should be gradual. Sudden acceleration, hard braking or sharp steering all break the thin film of grip available on a slippery surface, which is what causes skids. Treat the controls as if there is an egg under each pedal.
- Pull away in second gear where possible to reduce wheelspin.
- Brake early and gently, leaving up to ten times the normal gap.
- Steer smoothly and slow down before bends, not during them.
- Keep momentum on hills — avoid stopping on the way up.
- Use a high gear on packed snow to limit wheelspin.
Should you lower tyre pressure for snow?
No — lowering tyre pressure for snow is a myth. Running tyres under-inflated reduces overall grip, makes the car handle unpredictably, wears the edges of the tread and raises fuel use. Stick to the pressures in your handbook or door pillar, and check them when the tyres are cold for an accurate reading.
What about black ice and bridges?
Black ice is a thin, transparent layer that looks like wet road, and it forms first on bridges, flyovers and shaded spots because cold air circulates above and below them. The Met Office warns that these structures freeze before ordinary roads, so treat them with extra caution even when the rest of the route looks clear.
If you feel the steering go unusually light or the car drift, ease off the accelerator without braking hard, keep the steering steady and let the tyres find grip again. Reacting calmly matters more than reacting fast.
| Surface | Grip vs dry road | Driving response |
|---|---|---|
| Cold, wet tarmac | Reduced | Slow down, leave more space |
| Packed snow | Much reduced | Gentle inputs, high gear, big gaps |
| Sheet or black ice | Very low | Avoid braking and steering at once |
What should you keep in the car in winter?
A small winter kit turns a stressful snowy breakdown into a manageable wait. Even on short trips, the AA and Met Office both advise carrying a few basics in case you are delayed, stuck in traffic or unable to drive on safely after a tyre problem.
- Warm layers and a blanket in case you have to wait for help.
- An ice scraper and de-icer for clearing glass and mirrors fully before setting off.
- A charged phone and power bank to call for assistance.
- A torch, water and a snack for longer delays.
- A high-vis vest and warning triangle if you have to leave the car.
Clearing all your windows, lights and the roof of snow before you drive is also a legal expectation — driving with restricted vision or snow likely to fall onto the road can land you in trouble as well as being dangerous.
Do four-wheel drive and ABS replace good tyres?
No. Four-wheel drive helps you pull away and climb, but it does nothing extra to help you stop or steer on ice — braking and cornering grip still come entirely from the tyres. Likewise, ABS shortens stopping distances on many surfaces but cannot create grip that the tyre compound does not have on snow and ice.
This is the trap that catches confident 4x4 drivers: strong acceleration masks how little stopping grip is available until the moment they need to brake. Suitable cold-weather tyres remain the single biggest factor in winter safety, whatever the drivetrain. See our 4x4 and SUV tyres guide for more.
Should you avoid driving in heavy snow altogether?
Yes, where you can. Both the Met Office and the Highway Code advise not driving in snow and ice unless your journey is essential. No tyre fully removes the risk on a badly affected road, and the safest blowout, skid or stranding is the one you avoid by waiting for the gritters and the thaw.
If you must travel, check the forecast and traffic before setting off, tell someone your route and expected arrival, and allow far more time. Plan a way home and a fallback if conditions worsen. Good tyres make the journey safer, but judgement about whether to go at all is the first line of defence.
If you get stuck or stranded
If a tyre fails or you find yourself stranded in bad weather, do not risk driving on a damaged or unsuitable tyre to reach a garage. Fast Tyre's 24/7 emergency callout brings a fitter to your roadside or driveway across London and central England, usually within 30 to 60 minutes, with the right tyres for the conditions. Keep warm, stay with the vehicle where it is safe, and call for help.
Frequently asked questions
Up to ten times longer than on a dry road, according to the Highway Code (rule 126). The safe gap that works at speed in the dry becomes dangerously short on ice, so slow down early and leave far more space behind the car ahead.
They are not a legal requirement, but they help enormously. Cold-weather or all-season tyres with the 3PMSF snowflake symbol grip far better below 7°C. At minimum, make sure your existing tyres have plenty of tread — aim for 3mm or more.
No. Deflating tyres for snow is a myth that reduces overall grip and makes handling unpredictable. Keep tyres at the pressures in your handbook, check them when cold, and remember that cold weather already lowers pressure naturally.
Pull away gently in second gear to reduce wheelspin, and use higher gears than usual on packed snow to keep the wheels from spinning. Smooth, low-revving inputs help the tyres maintain the small amount of grip available.
Bridges and flyovers freeze before ordinary roads because cold air circulates both above and below them, as the Met Office notes. Black ice often forms there first, so slow down and avoid braking or steering sharply when crossing them.
