Data verified:
4 min readArgentina drives on the right side of the road. The minimum driving age is 17. The motorway speed limit is 130 km/h. The general emergency number is 911. Foreign drivers should carry an International Driving Permit (IDP) alongside their valid national licence.
Argentina: Winter tyres are required when conditions demand it, but defining those conditions is where it gets complex. Use our tyre checker to see exactly what you need.

Patagonia and the Andean regions are where Argentina’s situational winter tyre rule actually bites, mainly from June through September. Elsewhere the requirement simply doesn’t apply, since there’s no fixed nationwide date. Studded tyres are permitted on a seasonal basis in the affected regions, and tread may not drop below 1.6mm anywhere in the country.
For anyone behind the wheel in Argentina, visitor or resident alike, compliance takes minutes; contesting a fine abroad takes weeks.

Winter Tyre Requirements in Argentina
Argentina uses a situational winter tyre system. The period when winter conditions typically occur: June - September (Patagonia, Andean regions).
The law does not specify dates. It specifies conditions. When snow covers the road or ice forms on the surface, your vehicle must be on winter-rated tyres. The practical effect is that most drivers in Argentina switch tyres between October and April, but the legal trigger is weather, not the calendar.
Minimum Tread Depth in Argentina
In Argentina, the legal minimum tyre tread depth is 1.6 mm, measured across the central three-quarters of the tread width around the full circumference.
Safety organisations recommend that drivers in Argentina replace tyres at 3.0 mm rather than running them down to the legal limit. The difference in wet braking at 80 km/h:
| Tread Depth | Wet Braking (80 km/h) | Risk Level |
|---|---|---|
| 8 mm (new tyre) | ~26 metres | Low |
| 3 mm | ~32 metres | Moderate |
| 1.6 mm (legal minimum) | ~43 metres | High |
With motorway limits of 130 km/h in Argentina, adequate tread is critical. Aquaplaning risk increases sharply above 80 km/h, and a tyre near the 1.6 mm minimum cannot channel water fast enough at high speed.
Studded Tyres in Argentina
Studded tyres are allowed in Argentina during the winter season. Studs provide superior grip on sheet ice and hard-packed snow, but they reduce grip on dry and wet asphalt. They also increase road noise significantly. Use them only if you regularly drive on icy roads.
All-Season Tyres in Argentina
All-season tyres with the M+S marking are accepted in Argentina. For drivers who prefer not to switch tyres seasonally, they offer a practical middle ground — adequate in mild winters and acceptable in summer heat, though not optimal in either extreme.
Penalties for Tyre Violations in Argentina
Tyre violations in Argentina carry fines and may affect your licence. For context on enforcement severity: a seatbelt violation costs ARS 10,000-30,000 (approx. EUR 10-30), so expect tyre offences to be taken at least as seriously.
Choosing Tyres for Argentina’s Conditions
With diverse climate from tropical to temperate, there is no single tyre answer for all of Argentina:
- In the warmer north, summer tyres or all-season tyres handle conditions well year-round
- In cooler southern regions, temperatures can drop enough to affect summer tyre grip — consider all-season tyres if you drive there regularly
- Heat and UV degrade rubber faster than in temperate climates — check tyre age (DOT code on sidewall) and replace after 5 years regardless of tread
- Heavy rain is the biggest tyre hazard across most of Argentina. Keep tread well above the 1.6 mm legal minimum
Road Conditions and Tyre Wear in Argentina
Outside the main cities of Argentina, road surfaces deteriorate quickly. Expect potholes, loose gravel, and unpaved stretches on secondary routes.
Tyre survival tips for Argentina:
- A full-size spare is essential outside urban areas — space-savers are not enough
- Inspect sidewalls daily if you are driving on unpaved roads
- Lower tyre pressure slightly (by 0.2-0.3 bar) on soft sand or deep gravel, then reinflate on tarmac

Frequently Asked Questions
Argentina's temperate climate means all-season tyres with M+S marking are a practical year-round choice. However, if your area sees regular winter frost or snow, dedicated winter tyres from October to March will provide significantly better grip and shorter braking distances.
The legal minimum tyre tread depth in Argentina is 1.6 mm. However, tyre safety experts recommend replacing tyres at 3 mm for wet conditions and 4 mm before winter. At 1.6 mm, wet braking distance at 80 km/h is approximately 65% longer than with new tyres.
Winter tyres in Argentina are situationally required — you must have them when winter conditions (snow, ice, slush) are present on the road. There is no fixed date mandate, but driving without appropriate tyres in wintry conditions will result in a fine.
Studded tyres are not commonly used or regulated in Argentina. Given the climate, standard tyres appropriate for the season are sufficient for safe driving.
Reputable rental companies in Argentina should provide vehicles with season-appropriate tyres. Always confirm this when booking, especially if travelling during winter. Inspect the tyres when collecting the vehicle — check tread depth and look for visible damage. Report any concerns before driving away.
Argentina drives on the right. Tyre wear patterns may differ if your vehicle was designed for left-hand traffic, as weight distribution changes. Check tyre pressure monthly, inspect for damage regularly, and never mix tyre types on the same axle.
