Finland requires winter tyres between 1 Nov and 31 Mar whenever snow, slush or ice is on the road, with a 3 mm tread floor and 3PMSF on friction tyres. Judge the road on the day, not the date.

- How the EU tyre label grades wet braking and rolling resistance — What each letter and pictogram on the sticker actually measures.
- Tyre noise ratings in decibels — What the dB figure and the A, B or C class on the label mean inside the car.
- Calculate tyre pressure from your tyre size and load — A starting figure in bar and psi, then the door placard has the final word.

See how Finland differs from your home country
Finland raises its tread requirement rather than simply naming a date: between 1 November and 31 March, whenever snow, slush or ice covers the road, winter tyres are compulsory and the legal minimum climbs to 3 mm instead of the usual 1.6 mm. Studded tyres remain legal here, unlike in several neighbours, and since 1 December 2024 a non-studded winter tyre must carry the 3PMSF alpine symbol.
Your case: The calendar does not decide this, the road surface on the morning you set off does — which is why an October cold snap can already count and a mild February day may not. Driving in Finland covers what the same stop tests next: 120 km/h motorways, EUR 200 fixed for a visitor at 10 km/h over, and the income-based day fines behind it.

2026–27 Winter Season: Key Dates for Finland
For the 2026–27 season the winter tyre window runs 1 November 2026 – 31 March 2027, longer if the weather stays wintry. Fit winter tyres before the start date: fitting slots across Finland fill up quickly once the first frost arrives, and October is the busiest switching month.
- Studded tyres are allowed in season.

Winter Tyre Requirements in Finland
Finland has a condition-based winter tyre requirement inside the window 1 November - 31 March: winter tyres are compulsory whenever snow, slush or ice covers the road, and the police judge the conditions on the day.
Compliant tyres in Finland must carry: the 3PMSF alpine symbol if they are non-studded winter tyres, a rule in force since 1 December 2024. Studded tyres are winter tyres by definition.
Practical advice for Finland:
- Fit winter tyres before the mandate starts; garages get fully booked in the final weeks
- The legal winter floor is 3 mm, but 4.0 mm is the practical minimum for winter grip
- Keep a margin on the date: a wintry road on 25 October already triggers the duty
Minimum Tread Depth in Finland
The general legal minimum is 1.6 mm, measured across the central three-quarters of the tread width around the full circumference. On winter tyres, while the winter rule applies, the floor is 3 mm.
Tyre professionals in Finland advise changing winter tyres at 4.0 mm. Grip on snow and slush falls away well before the legal floor, and at 120 km/h on a wet motorway a tyre near the minimum cannot clear water fast enough.

Penalties for Tyre Violations in Finland
Tyre violations in Finland carry fines and may affect your licence. For context on enforcement severity: a seatbelt violation costs EUR 70, so expect tyre offences to be taken at least as seriously.
On-the-spot fines: Finland issues fines at the roadside. Carry sufficient cash or a card to pay immediately.
Seasonal Tyre Management in Finland
- October–November: switch to winter tyres. Book your garage appointment early, slots fill fast
- March–April: switch back to summer tyres once night frosts end consistently; the winter rule can outlast 31 March if the roads stay wintry
- Year-round: check pressure monthly, and again after the first hard frost
- Depth check: winter tyres lose effectiveness below 4.0 mm tread even though the legal winter floor is 3 mm

Frequently Asked Questions
Yes, conditionally. Between 1 November and 31 March winter tyres are compulsory whenever the weather or the road surface calls for them; on a dry, bare road inside that window they are not. Since 1 December 2024 a non-studded winter tyre must carry the 3PMSF alpine symbol, and any winter tyre must have at least 3 mm of tread.
1.6 mm for ordinary tyres all year, and 3 mm for winter tyres while the winter rule applies. Finnish tyre professionals advise changing winter tyres at 4 mm, well before the 3 mm floor.
Yes. Studs are legal through the winter tyre season and may stay on longer while conditions remain wintry. On bare, dry asphalt they lengthen braking distances and wear faster, which is why many Finnish drivers run friction tyres instead.
Only if they carry the 3PMSF alpine symbol. Since 1 December 2024 an M+S marking alone is not enough for a non-studded winter tyre, and the 3 mm floor applies to the tyre either way.
Between November and March a Finnish rental will normally come on winter tyres, studded or friction, because the hire firm is bound by the same rule. Confirm it in writing when booking, and check the tread and sidewalls before driving away.
Finland drives on the right. Check tyre pressure monthly, inspect for damage regularly, and never mix tyre types on the same axle. Elk and reindeer on the road are a bigger winter hazard than the snow itself.
