Motorhome winter tyres & snow chains in Europe (2026)
There is no single European winter-tyre rule — four countries do it four ways. France requires winter equipment from 1 November to 31 March in signposted mountain zones (about 34 departments), motorhomes over 3.5 t included. Austria (1 Nov–15 Apr) and Germany apply a situative rule — equipment only when the road is snowy or icy — but Germany accepts only 3PMSF (3-Peak Mountain Snowflake) tyres. Italy leaves it to regional ordinances. The setup that covers every country: four 3PMSF winter tyres plus a set of chains carried on board. In France and Austria, chains on at least two driven wheels are an accepted alternative on snow.
Winter equipment is one of those rules that changes at every border, which makes it easy to get wrong on a long alpine trip. This page sets out the four regimes a motorhome is most likely to meet — France's loi Montagne, Austria's §102 KFG (the Motor Vehicle Act rule), Germany's §2 StVO (the road-traffic-code rule), and Italy's patchwork of regional ordinances — and what each accepts as valid equipment. The through-line is simple: fit 3PMSF tyres and carry chains, and you satisfy the strictest country on your route. The facts are dated and sourced; winter rules are revised most years, so check before you set off.
- No single rule — fit 3PMSF
- Four countries, four regimes, no Europe-wide mandate. The one choice that works everywhere: four 3PMSF (3-Peak Mountain Snowflake) winter tyres plus chains carried on board. Germany is the strictest, so 3PMSF is the safe common denominator.
- France — loi Montagne
- 1 Nov–31 Mar, in signposted communes across ~34 departments (B58/B58a signs). Camping-cars included, even over 3.5 t. 3PMSF tyres or chains on >=2 driven wheels; M+S alone no longer counts. The €135 fine is written in but still not being issued.
- Austria & Germany — situative
- Austria (§102 KFG, 1 Nov–15 Apr) and Germany (§2 StVO, no fixed dates) require equipment only when the road is snowy/icy. Austria accepts M+S or 3PMSF; Germany, 3PMSF only since Oct 2024. Austrian enforcement is real (on-the-spot fine from ~€35).
- Italy — regional
- No national law: regional and road authorities post their own seasonal ordinances (roughly Nov–Mar), shown by local signs. M+S is often still accepted. Check the region or pass before you travel.
No single European rule
There is no Europe-wide winter-tyre law. Each country sets its own, and the differences are real enough to catch out a motorhome crossing two or three borders in a week. Before the country detail, one marking is worth understanding, because it's the key to travelling simply.
- M+S (Mud + Snow): a manufacturer's marking with no snow-grip test behind it. Long treated as "winter enough" — no longer, in the strictest countries.
- 3PMSF (3-Peak Mountain Snowflake): a symbol of a mountain with a snowflake, awarded only after a snow-grip test. This is the marking that now counts in France and Germany, and is always accepted where M+S is.
That gives the simple rule for the whole trip: fit 3PMSF tyres and carry chains. A 3PMSF tyre is accepted in every country below; chains cover the steepest snowbound sections where even good tyres want help. Everything after this is the country-by-country detail — the kind of rule layer a motorhome navigation app should surface before the mountain, not at the pass.
France — the loi Montagne
France's loi Montagne (décret 2020-1264) sets a fixed season and fixed zones. From 1 November to 31 March, in the communes each mountain prefecture designates — roughly 34 departments across five massifs (Alps, Massif Central, Jura, Pyrenees, Vosges) — every vehicle must carry winter equipment. The zones are marked on the road by the B58 sign (entering) and B58a (leaving).
- What counts: four 3PMSF winter tyres, or chains / textile snow socks fitted to at least two driven wheels. Since 1 November 2024, the M+S marking on its own no longer qualifies — the phase-in is over.
- Motorhomes included: the decree names camping-cars explicitly and does not exempt vehicles over 3.5 tonnes / 3,500 kg.
- The fine, honestly: a €135 fine is written into the decree, but no sanction decree has been signed — this is the fifth winter of "pedagogy," so officers advise rather than fine (Sénat written answer QE 06613). The obligation is real all the same; the equipment is what gets you over the pass.
The French-language deep-dive, pneus hiver et loi Montagne en camping-car, walks the departments and the signage in detail.
Austria — §102 KFG
Austria's rule lives in §102 of the KFG (Kraftfahrgesetz, the Motor Vehicle Act) and, for most motorhomes, is situative — it applies only when the road is actually wintry. The season framing runs 1 November to 15 April.
- Most motorhomes (class M1): in snow, slush, or ice, you need winter tyres on all wheels or chains on at least two driven wheels. Austria accepts either M+S or 3PMSF — it hasn't followed Germany's 3PMSF-only shift. A motorhome over 3.5 t is still class M1 if that's what the registration says.
- Heavier N-class rigs: the few motorhomes registered as goods vehicles (class N) over 3.5 t face a stricter, date-based version — winter tyres on a driven axle for the whole period, plus chains carried.
- What decides it: the vehicle class in the registration papers (Zulassungsschein), not the weight alone.
- Enforcement is real: an on-the-spot fine (Organmandat) starts around €35, and police can stop you continuing until the vehicle is equipped.
The German-language Austria deep-dive, Winterreifenpflicht in Österreich fürs Wohnmobil, covers the M1-versus-N split and the profile-depth minimums.
Germany — §2 StVO
Germany's rule sits in §2 of the StVO (Straßenverkehrs-Ordnung, the road-traffic code) and is purely situative — there are no fixed dates. When the road is icy, snow-slick, or slushy, winter tyres are required.
- What counts: since 1 October 2024, only 3PMSF tyres qualify. An M+S tyre made before January 2018 is no longer legal winter equipment.
- Motorhomes: the same rule as cars — no special exemption.
- If you're caught unequipped in wintry conditions: a fine from around €60 and a demerit point.
This is the country that makes 3PMSF the sensible default: because Austria still accepts M+S but Germany does not, a single set of 3PMSF tyres keeps you legal across both.
Italy — regional ordinances
Italy has no single national winter-tyre law. Instead, regional authorities and road operators (ANAS, the Regioni) issue their own seasonal ordinances, typically running from mid-November to mid-April, on the roads and passes they choose. Local signs — not a national rule — tell you when equipment is required.
- What counts: ordinances usually accept M+S or 3PMSF tyres, or chains carried on board; the exact wording varies by region.
- How you know: watch for the roadside sign at the start of a regulated stretch (often "obbligo catene o pneumatici invernali").
- Practical take: because it's a patchwork, the safe approach is the same as everywhere else — 3PMSF tyres on the vehicle and chains in the locker.
The four rules side by side
| Country | When | What qualifies | Enforcement |
|---|---|---|---|
| France (loi Montagne) | 1 Nov–31 Mar, signposted zones (~34 depts) | 3PMSF tyres, or chains on ≥2 driven wheels (M+S no longer counts) | €135 written in, not yet issued |
| Austria (§102 KFG) | 1 Nov–15 Apr, situative (M1) | M+S or 3PMSF, or chains on ≥2 driven wheels | Real; on-the-spot fine from ~€35 |
| Germany (§2 StVO) | Situative, no fixed dates | 3PMSF only (since Oct 2024) | From ~€60 + demerit point |
| Italy | Regional ordinances, ~Nov–Apr | Varies; often M+S or 3PMSF, or chains | Per regional ordinance |
Read across the table and the same answer keeps returning: 3PMSF tyres plus chains satisfy every column. Fit that once and the border you cross stops mattering.

FAQ
Do I need winter tyres to drive a motorhome in Europe in winter?
It depends on the country, and there is no single European rule. France requires winter equipment from 1 November to 31 March in signposted mountain zones (about 34 departments). Austria and Germany apply a 'situative' rule — winter equipment only when the road is actually snowy or icy — but Germany accepts only 3PMSF-marked tyres. Italy leaves it to regional ordinances. The one choice that works everywhere: fit four 3PMSF (3-Peak Mountain Snowflake) winter tyres and carry a set of chains. That covers the strictest country you'll cross.
What is the difference between M+S and 3PMSF tyres?
M+S (Mud + Snow) is a manufacturer's marking with no performance test behind it. 3PMSF (3-Peak Mountain Snowflake) — a small symbol of a mountain with a snowflake — is awarded only after a snow-grip test. The two used to be treated alike; that's changing. France (since 1 November 2024) and Germany (since 1 October 2024) now count only 3PMSF. Austria still accepts either. Because Germany is the strictest, a 3PMSF tyre is the safe choice for any cross-border trip.
Does the loi Montagne apply to a motorhome over 3.5 tonnes?
Yes. France's loi Montagne names camping-cars explicitly and does not exempt vehicles over 3.5 tonnes / 3,500 kg. In the signposted communes, from 1 November to 31 March, your motorhome needs four 3PMSF tyres or chains fitted to at least two driven wheels. The requirement is real. The €135 fine written into the decree, on the other hand, still isn't being issued — a fifth winter of 'pedagogy' with no penalty decree signed. Carry the equipment because it's what gets you through the pass, not because of the fine.
Do snow chains count instead of winter tyres?
Often, yes — as an alternative, not everywhere. In France's loi Montagne zones and in Austria, chains fitted to at least two driven wheels satisfy the rule in place of 3PMSF tyres, but chains only work on a road actually covered in snow or ice (you can't run them on bare tarmac). Germany's situative rule is built around winter tyres rather than chains. The practical setup for a mountain motorhome trip is 3PMSF tyres on the vehicle plus chains carried for the steepest, snowiest sections.
