Winter TyresWinter Tyres in Argentina: Patagonia & the Andes (Jun–Sep)
Argentina winter tyre rules involve more than just a mandate. Tread depth, tyre age and all-season acceptance vary. Verify your setup below.
Winter tyres are situationally required in Argentina. This typically covers: June - September (Patagonia, Andean regions).
Southern-hemisphere winter — June to September
Argentina is a southern-hemisphere country, so its winter falls June to September — the opposite of Europe — and winter tyres only really matter in the Andes and Patagonia. On the ski-area approaches (Bariloche, Las Leñas) and high mountain passes, snow chains are frequently required and police check at control points, sometimes refusing entry without them. Across the vast lowland majority of the country you’ll never need winter rubber. If you’re driving Ruta 40 or crossing to Chile over an Andean pass in those months, carry chains, check whether the pass is open, and never set out over a summit in a storm — many close at short notice.
Argentina Winter Tyre Regulations
Argentina follows a situational winter tyre rule.
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 June - September (Patagonia, Andean regions).

The legal minimum tread depth in Argentina is 1.6 mm.

How Strictly Is This Enforced?
Enforcement varies by region. Mountain areas and busy transit corridors see the most checks. Rental agencies in Argentina usually handle tyre changes, but always verify before driving away.
All-Season Tyres: Good Enough?
Argentina 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.

Insurance Implications
Driving without legally required winter tyres in Argentina 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 Argentina 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.
