When to change to summer tyres: timing the spring switch

Calculator →

Deciding when to change to summer tyres is the mirror image of the autumn switch. Change too early and a late frost or snow shower can catch you on the wrong tyres. Wait too long and your winter tyres wear quickly on warm roads and brake less well than summer tyres. This guide explains how the 7 °C rule works in spring, why the last frost matters and how the TyreSwitch calculator finds your personal window for the 2026/2027 season.

The short answer

Switch back to summer tyres once the average daily temperature has settled above about 7 °C and stays there, and once the last frost and snow of the season are behind you. TyreSwitch turns that into a concrete window based on your location, the roughly 10-day forecast, climate averages and the way you drive. As always, the final decision is yours.

The 7 °C rule in reverse

In autumn, the 7 °C threshold marks the point where summer tyre rubber becomes too hard for good grip. In spring, the same threshold tells you that the soft compound of winter tyres is no longer an advantage. On warm, dry roads, that soft rubber flexes more, wears faster and generally gives longer braking distances than a summer tyre designed for those conditions.

TyreSwitch looks at the rolling 5-day average of the daily mean temperature and finds the first day from which it stays above 7 °C. The best days start the day after the last frost or likely snow, so a single warm week in March followed by a cold snap does not trigger a premature switch.

How the spring window is labelled

Once the weather has warmed up for good:

  • Best: the first 7 days after it warms up.
  • Good time: 8 to 21 days after it warms up.
  • Overdue: more than 21 days after. At this point your winter tyres are wearing faster than necessary and braking less well than summer tyres would.
  • Too early: while the 5-day average is still below the threshold or frost and snow are still expected.

Days beyond the roughly 10-day forecast are climate-projected estimates and are never labelled better than “good time”. The recommendation becomes sharper as the season moves into the forecast range, so it is worth checking back every few days.

How your driving changes the spring date

The same profile you use in autumn also adjusts the spring recommendation, this time pushing the date later rather than earlier where extra caution makes sense.

Driving experience

If you have been driving for less than two years, TyreSwitch uses a threshold of 8 °C instead of 7 °C and moves the window about 5 days later. A little more time on winter tyres gives extra margin against a late cold spell.

Roads you use

  • Mountain roads: treated as 1.5 °C colder than your location, so the window comes later. Snow can linger at altitude long after valleys feel like spring.
  • Rural roads: the window moves about 2 days later, because untreated country roads can stay icy on cold mornings.

Time of day

If you drive early in the morning or at night, TyreSwitch uses the temperatures at those hours, which are often well below the daily mean. Beyond the forecast range, it uses the average daily minimum from climate data. Early starters may therefore see a slightly later window than drivers who only travel at midday.

How often you drive

Occasional drivers get the same dates with softer wording.

Workshop timing

Spring is the second rush season for tyre fitters. TyreSwitch suggests booking 7 to 10 days before your best window starts. If you change wheels yourself, it is a good moment to clean and inspect your winter set before storing it.

Before you store your winter tyres

  • Check the tread depth and look for damage, so you know in good time whether you need a new set next autumn.
  • Mark each tyre with its position on the car, which makes it easier to rotate them next season.
  • Store tyres in a cool, dry and dark place, away from fuel, solvents and direct sunlight.
  • Check the condition and tread of your summer tyres before fitting them.

All-season tyres and the off-season

If you use all-season tyres, there is nothing to change in spring. Between 16 June and 14 August, TyreSwitch shows that no change is needed and gives you an outlook for the next expected window based on climate data.

In countries with fixed winter tyre periods, you must keep winter tyres on until the period ends, even if the weather has already warmed up. The weather-based recommendation and the legal requirement are shown separately in TyreSwitch. See our overview of winter tyre laws in Europe for country summaries. This is general information, not legal advice; please check the current local rules.
