Winter TyresWinter Tyres in France: 34 Mountain Areas (Loi Montagne)
The answer for France changed with recent regulation updates. Marking standards, enforcement strictness and rental car policies all matter. Details below.
In France, you must fit winter tyres when road conditions require them. The rule applies during: 1 Nov - 31 Mar (mountain law, designated departments).
The Loi Montagne covers 34 départements
France’s Loi Montagne requires winter tyres or snow chains from 1 November to 31 March across 34 designated mountain départements — the Alps, Pyrenees, Massif Central, Jura and Vosges — marked with special signs at their boundaries. Outside those areas there’s no requirement. Importantly, an acceptable winter tyre must now carry the 3PMSF ‘snowflake’ symbol; the old M+S marking alone is no longer enough. Enforcement has been light so far, but the legal basis for a fine and, more importantly, liability in a crash, is real. If you’re driving to a French ski resort or over an Alpine pass in winter, fit 3PMSF tyres or keep chains in the boot.
Winter Tyre Rules in France
Rather than a fixed calendar mandate, France requires winter tyres when conditions demand them.
This means that whenever roads are covered with snow, ice, slush, or black ice, your vehicle must be equipped with appropriate winter or all-season tyres.
In practice, this typically applies during 1 Nov - 31 Mar (mountain law, designated departments).
Minimum Tread Depth
The legal minimum tread depth in France is 1.6 mm.
For winter driving, a tread depth of at least 3.0 mm is strongly recommended.
Studded Tyres
Studded tyres are allowed with restrictions in France. They may only be used during specific months.
All-Season Tyres
All-season tyres (marked M+S or 3PMSF) are accepted in France as a winter alternative.

Check Tyre RequirementsWhat Most Guides Don’t Tell You
How Strictly Is This Enforced?
Police in France 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.
Foreign-plated vehicles are not exempt. Rental companies in France typically fit winter tyres during the mandatory period, but always confirm at pick-up.
Tyre Marking Requirements
Accepted marking in France: M+S or 3PMSF.
The Three-Peak Mountain Snowflake (3PMSF) symbol is increasingly becoming the only accepted winter marking across Europe. Tyres with only the older M+S stamp may not pass inspection in France depending on production date.
All-Season Tyres: Good Enough?
France accepts all-season tyres as a winter alternative, provided they carry the correct marking. They work well for mild winters and mixed driving.
However, dedicated winter tyres outperform all-seasons below 7 degrees Celsius. If your route includes mountain passes or areas with regular snowfall, a dedicated set is the safer choice.
Studded Tyres
Studded tyres are permitted in France only during specific months and on certain road types. Check the local rules carefully before fitting studs, especially when crossing borders from a country where they are freely allowed.
Insurance Implications
Driving without legally required winter tyres in France can void your insurance in the event of an accident. Even if you are not at fault, the insurer may reduce your payout if your vehicle was not compliant at the time of the incident.
Tread Depth Reality
The legal minimum in France is 1.6 mm, but tyre performance drops sharply below 3.0 mm. Replacing tyres before they hit the legal limit gives you a meaningful safety margin on wet or icy roads.
