Winter Tyres in Romania: Required Nov–Mar on Snow and Ice

Yes, winter tyres are legally required in Romania. The mandatory period is 1 Nov - 31 Mar. Minimum tread depth is 1.6 mm.

Tied to the conditions — but the Carpathians deliver them

Romania’s rule runs 1 November to 31 March and is tied to the conditions: winter tyres are required when roads are covered in snow, ice or slush, which — given the Carpathians run right through the country — happens often and early. The tyres must be fitted to all wheels, not just the driven axle, and the minimum tread is 1.6mm. Police check during winter weather, and driving on summer tyres in snow brings a fine. If your route crosses the mountains (the Transfăgărășan is closed in winter anyway, but many passes stay open), fit proper winter tyres for the season and don’t rely on a mild forecast holding.

Winter Tyre Rules in Romania

Drivers in Romania must equip winter tyres during the designated period.

The mandatory period runs from 1 Nov - 31 Mar. During this window, every vehicle on public roads must be fitted with approved winter tyres.

Tyres must carry the M+S or 3PMSF marking to be considered compliant.

The legal minimum tread depth in Romania is 1.6 mm.

Safety experts recommend maintaining at least 4.0 mm of tread for adequate winter grip.

Studded Tyres

Studded tyres are prohibited in Romania. Using them can result in a fine.

What Most Guides Don’t Tell You

How Strictly Is This Enforced?

Police in Romania 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 Romania: 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 Romania depending on production date.

All-Season Tyres: Good Enough?

Romania 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

Romania bans studded tyres entirely. Using them — even temporarily — carries a fine and may void your insurance.

Insurance Implications

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

Tread Depth Reality

The legal minimum in Romania is 1.6 mm, but tyre performance drops sharply below 4.0 mm. Replacing tyres before they hit the legal limit gives you a meaningful safety margin on wet or icy roads.
