Studded tyre season: rules, dates, and fines explained
When you can run studs, what the police actually enforce, and why the dates exist.
Every autumn, the same question pops up in Facebook groups: can I put my studs on yet? Here's the actual law.
The legal window
Studded tyres are permitted on Icelandic roads from 1 November to 14 April. Outside that window, running studs is a 20 000 ISK fine per axle.
The minister can extend the window in either direction if weather warrants — this happened in spring 2023 when a late storm pushed the deadline to 22 April.
Why the dates exist
Studs wear asphalt aggressively, especially in the southwest where road temperatures stay above freezing for most of summer. The cost of repaving is one of the largest line items in Vegagerðin's budget.
Practical tips
- Book your tyre change a couple of weeks before the season — wait too long and the queues at dekkjaverkstæði hit 2-week wait times.
- All four corners must match. Mixing studded and unstudded is illegal and dangerous.
- New studs need a 500 km bedding-in period at moderate speed and gentle braking.
What about EVs?
Studs add roughly 5–8% to rolling resistance, which directly cuts range. If you drive mostly in the city and rarely hit ice, modern friction tyres are a perfectly defensible choice.
