Winter Tyres❄️ Winter Tyres Finland 2026-27 — Required 1 Nov–31 Mar, 3mm
The answer for Finland changed with recent regulation updates. Marking standards, enforcement strictness and rental car policies all matter. Details below.
Finland requires winter tyres by law. The mandatory period is 1 Nov - 31 Mar (can be extended by conditions). Minimum tread depth is 1.6 mm.
The land of the studded tyre — and the reindeer
Finland requires winter tyres 1 November to 31 March, and the period can be extended when conditions demand — which, this far north, they often 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 tread is 1.6mm, 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 enforces a strict winter tyre law.
The mandatory period runs from 1 Nov - 31 Mar (can be extended by conditions). During this window, every vehicle on public roads must be fitted with approved winter tyres.
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.

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

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.

Insurance Implications
Although winter tyres are not legally mandated in Finland, some insurers reduce payouts if an accident occurs in winter conditions with summer tyres fitted. Check your policy wording.
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.
