Winter TyresFinland Winter Tyres 2026-27: 1 Nov-31 Mar, 3 mm Floor
Finland's rule is conditional: winter tyres from 1 Nov to 31 Mar whenever weather or road conditions demand them. The winter tread minimum is 3 mm; 1.6 mm is the summer figure.
Finland requires winter tyres between 1 November and 31 March whenever weather or road conditions call for them. The obligation has been condition-based since the Road Traffic Act 729/2018 replaced the old fixed December-to-February window in June 2020. The tread floor for a winter tyre is 3.0 mm — the familiar 1.6 mm figure is the summer-tyre minimum and will not keep you legal on a Finnish winter road.
The land of the studded tyre — and the reindeer
Finland requires winter tyres 1 November to 31 March whenever weather or road-surface conditions demand them — which, this far north, they usually do. This is heartland studded-tyre (nastarenkaat) country: studs are legal through the winter and widely used to bite into packed ice, though some city streets restrict them to limit dust. The legal minimum for a winter tyre is 3.0 mm, but on Finnish ice you’ll want far deeper, softer winter rubber. Beyond the tyres, the real hazard up here is wildlife: reindeer in Lapland and elk further south wander onto roads at dawn and dusk, and a collision at speed is far more dangerous than any fine. Rental cars come fitted for the season — check road conditions before longer trips into the north.
What the Law Says About Winter Tyres in Finland
Finland’s winter tyre rule is written as a condition, not a calendar.
Between 1 November and 31 March, a vehicle on a public road must be on winter tyres whenever the weather or the road surface calls for them. In practice that covers most of the period across most of the country, and the police make the judgement at the roadside — so the safe reading is: fit them for the whole window.
Tyres must carry the 3PMSF (min 3 mm tread for winter tyres) marking to be considered compliant.
Minimum Tread Depth
For winter tyres the legal minimum in Finland is 3.0 mm — 1.6 mm is the summer-tyre minimum.
Safety experts recommend maintaining at least 4.0 mm of tread for adequate winter grip.
Studded Tyres
Studded tyres are allowed in Finland.
All-Season Tyres
Finland does not accept all-season tyres as a substitute for winter tyres during the mandatory period.

Check Tyre RequirementsWhat Most Guides Don’t Tell You
How Strictly Is This Enforced?
Police in Finland can issue on-the-spot fines for non-compliant tyres during roadside checks. This is especially common at border crossings and mountain passes during winter months.
Tyre Marking Requirements
Accepted marking in Finland: 3PMSF (min 3 mm tread for winter tyres).
All-Season Tyres: Good Enough?
Finland does not accept all-season tyres as a substitute for dedicated winter tyres. Make sure your tyres are specifically rated for winter conditions.
Studded Tyres
Insurance Implications
Because the Finnish requirement is condition-based, an accident on summer tyres in wintry conditions is not just a traffic matter — it is evidence that the vehicle was not legal at the time. Insurers can and do reduce payouts on that basis. Check your policy wording before you travel.
Tread Depth Reality
For winter tyres the legal minimum in Finland is 3.0 mm — 1.6 mm is the general year-round figure and will not keep you legal in wintry conditions. Replacing tyres before they hit the legal limit gives you a meaningful safety margin on wet or icy roads.

Conditionally, yes. Since the Road Traffic Act 729/2018 took effect in June 2020, winter tyres are required from 1 November to 31 March whenever weather or road-surface conditions call for them — the police judge the conditions. The old fixed 1 December to 28 February window no longer applies.
Two figures, and mixing them up is the common mistake: winter tyres must have at least 3.0 mm of tread during the winter period, while 1.6 mm is the general year-round minimum that applies to summer tyres.
Yes. Finland is studded-tyre country — nastarenkaat are legal through the winter and widely used on packed ice. Some city streets restrict them to limit road dust, and several countries you might drive on to ban them outright, so check before crossing a border on studs.
