Key takeaways
- Winter cold, road salt and a season of potholes leave tyres more likely to show damage by spring, so it is the ideal time to check.
- Cold weather lowers tyre pressure, so many cars run under-inflated by the end of winter and need resetting as temperatures rise.
- Look for pothole damage in particular: bulges, cuts and buckled wheels from winter's worst road surfaces.
- The legal tread minimum is 1.6mm, but check now so worn tyres are replaced before the summer driving season, not during it.
Winter is the toughest season for tyres. Months of cold, road salt, standing water and a fresh crop of potholes leave their mark, and a lot of it goes unnoticed until spring. A proper check as the weather warms finds the damage early, resets pressures that have drifted with the cold, and gets you ready for the summer miles ahead. Here is what to look at and why spring is the right moment.
Why check your tyres in spring?
Spring is the ideal time to check because winter is hard on tyres in ways that show up slowly. Cold lowers pressure, salt and grit accelerate wear and corrosion, and the freeze-thaw cycle leaves roads full of potholes. A tyre that survived winter may be carrying impact damage, a slow puncture or simply low tread that you would rather find now than on a summer trip.
Doing it in spring also means any worn tyres get replaced before the busy driving season, not during it. You avoid the rush, and you head into longer, faster summer journeys on tyres you have actually looked at. Think of it as the tyre equivalent of a spring service.
How does winter damage tyres?
Winter damages tyres mainly through cold, salt and potholes. Low temperatures drop tyre pressure and make rubber stiffer and more brittle. Road salt and grit speed up wear and can corrode wheels and valves. Worst of all, the freeze-thaw cycle breaks up road surfaces, so winter is peak season for the pothole impacts that bulge tyres and buckle wheels.
Standing water and slush also hide hazards, so it is easy to clout a deep pothole without realising. The damage, a small bulge or a slow leak, may only become obvious weeks later. That is why a deliberate spring inspection catches things a quick winter glance missed. Our guide on potholes and tyre damage explains what to look for after an impact.
Should you reset your tyre pressures?
Yes. Air contracts as it cools, so tyre pressure falls in cold weather, and many cars run under-inflated by the end of winter. As temperatures climb in spring, check and reset every tyre to the correct cold figure on your door placard. Under-inflation wastes fuel, wears the edges and reduces grip, so this simple reset is worth doing.
Check cold, before you drive, because the figures assume cold tyres. If a tyre needs noticeably more air than the others, or keeps dropping after topping up, suspect a slow puncture rather than normal seepage. A winter pothole or a corroded valve are common culprits. Our guide on checking your tyre pressure covers it step by step.
| Spring check | What winter does |
|---|---|
| Reset pressures | Cold weather lowers pressure over the season |
| Inspect sidewalls | Potholes cause bulges, cuts and splits |
| Check tread and wear | Salt and wet roads accelerate wear |
| Look at the wheels | Impacts buckle rims; salt corrodes alloys and valves |
| Review tyre age | Cold and damp can worsen cracking on older rubber |
What tread and wear should you look for?
Check tread depth and the wear pattern, because winter often reveals both. The legal minimum is 1.6mm across the central three-quarters, but most safety bodies advise replacing at around 3mm for wet grip, which spring and summer rain still demand. Use the 20p test across the inner, middle and outer grooves on every tyre.
Look closely at how the tyre has worn. Heavier wear on one edge usually means the alignment is out, which a winter pothole can easily knock askew. Centre or both-edge wear points to pressure being wrong. Catching an alignment fault now stops it ruining your tyres over the summer. Our guide on reading tyre wear patterns helps you find the cause.
Is spring the time to swap winter tyres?
If you fit winter or cold-weather tyres, spring is the time to swap back to summer or all-season tyres. Winter tyres use a softer compound that wears faster and feels vaguer once temperatures climb above around 7C, so running them through summer costs you tread and fuel. The changeover point is roughly when daytime temperatures stay consistently mild.
When you swap, it is also the moment to inspect the tyres coming off, check the ones going on for age and cracking, and store the set you are removing correctly. Many drivers in milder parts of central England run all-season tyres year-round and skip the swap entirely, in which case the spring check still applies, just without the changeover.
Found winter damage?
A spring check is only worth doing if you act on what it finds. A bulge, a tyre that keeps losing air or tread that will not last the summer all mean replacement. For the bigger seasonal picture, our long-drive tyre checklist is a useful companion before the first big trip of the year. If you find damage, Fast Tyre brings mobile tyre fitting to your home or roadside across London and central England, so winter's toll is sorted before summer begins.
Frequently asked questions
Winter is hard on tyres: cold lowers pressure, salt accelerates wear, and potholes cause impact damage. A lot of it shows up slowly, so a spring check finds problems early and lets you replace worn tyres before the busy summer driving season rather than during it.
Yes. Air contracts as it cools, so tyre pressure falls over winter and many cars end the season under-inflated. As temperatures rise in spring, check and reset every tyre cold to the figure on your door placard, since under-inflation wastes fuel and wears the edges.
Look for bulges, cuts or splits in the sidewalls, buckled or cracked wheel rims, and tyres that have started losing air. A bulge means internal damage and the tyre must be replaced. Winter's freeze-thaw potholes are the main cause, and damage can appear weeks later.
If you run winter tyres, yes. Their softer compound wears faster and feels vaguer above about 7C, so running them through summer costs tread and fuel. Swap to summer or all-season tyres once daytime temperatures stay consistently mild, and inspect both sets as you change over.
The legal minimum is 1.6mm, but aim to replace at around 3mm for good wet grip through the spring and summer rain. Use the 20p test across the inner, middle and outer grooves on every tyre, and check the wear pattern for alignment faults from winter potholes.
