Studded winter tyres become legal in Iceland on 15 October. If you are renting a car or driving your own vehicle in Iceland from mid-October through spring, this date marks the point at which studded tyres are permitted on Icelandic roads.
The Icelandic Road and Coastal Administration (Vegagerðin) sets these dates annually. In 2026, the permitted window for studded tyres is 15 October to 15 April.
What This Means for Rental Car Drivers
Iceland’s car rental market adjusts to these regulations automatically. Most rental companies equip vehicles with non-studded winter tyres from around October — these are legal year-round and meet the requirement for winter conditions without the road wear restrictions that apply to studded tyres.
From 15 October, rental companies may also offer or automatically fit studded tyres on 4WD vehicles. When booking a rental car for travel from mid-October onwards, confirm with the rental company what tyre type the vehicle carries. On icy highland roads or the Ring Road in winter snowfall, studded tyres provide meaningfully better grip, particularly on compacted ice.
Key questions to ask your rental company:
- Are winter tyres fitted? (required in practice for safe winter driving, though not technically mandatory)
- Are they studded or non-studded?
- Is it possible to upgrade to studded tyres for an additional cost?

The Studded Tyre Rules
Studded tyres are permitted only between 15 October and 15 April — using them outside this window damages road surfaces and is illegal. The spring removal deadline is enforced, and tyre-related fines in Iceland are not trivial.
All four tyres on a vehicle must be the same type. Mixing studded and non-studded tyres is illegal.
On rental cars, this is handled by the company. On personal vehicles driven into Iceland (arriving by ferry from Denmark or UK), drivers must ensure their tyres comply before the dates.
Road Conditions from October Onward
October is when Iceland’s roads transition decisively to winter conditions. The main changes to expect:
-
Ring Road (Route 1): Passable year-round, but ice, snow, and reduced visibility become common after mid-October. The road is kept open and treated, but it can close temporarily after heavy snowfall.
-
Mountain roads: The highland F-roads closed in late September and early October for the season — these are not accessible in winter regardless of tyre type.
-
Passes: Several mountain passes, including the Öxi pass (Route 939) in the East Fjords, can close with short notice in heavy snowfall. road.is provides live closure information.
The Icelandic Met Office (vedur.is) and Vegagerðin (road.is) are the two essential sources before any long drive. Both sites have English-language versions and are updated several times daily.
Specific Rules for October Visitors
If you are arriving in Iceland between mid-October and April for the first time, a few practical points:
Road closures are real. Unlike some European destinations where winter weather is cosmetic, Icelandic roads close when conditions are hazardous. Check road.is every morning during a winter trip, not just at the start.
Speed limits with winter conditions. Iceland’s standard limits (90 km/h on paved roads, 80 km/h on gravel, 50 km/h in built-up areas) apply in dry conditions. In snow or ice, the posted limits represent maximums — safe speed may be significantly lower.
The Safe Travel plan. Filing a travel plan at safetravel.is before long winter drives takes two minutes and means the Icelandic Search and Rescue (ICE-SAR) knows your route and expected return time if you do not file a completion report.
Our Iceland winter driving guide covers road closures, weather code alerts, and how to interpret the colour-coded warning system that Vegagerðin uses for road conditions.
