Now that spring warmth is starting to be felt in many parts of the country, it's easy to think that winter is over. For many car owners, summer tires are tempting, not least because studded tires wear out more on bare asphalt and summer wheels are often ready in the garage. But despite milder weather, it may be wise to wait a little longer with the tire change.
According to the Transport Agency (Transportstyrelsen), passenger cars, light trucks, and light buses must have winter tires between December 1 and March 31 if there are winter road conditions. Winter road conditions mean that there is snow, ice, slush, or frost on some part of the road, and it is the police who decide what applies at the location. Studded tires are allowed to be used until April 15, and even later if winter road conditions are expected.
The question has become particularly relevant after a recent segment on P4 Jämtland, where Andreas Leithe from a tire company in Östersund reports that many have already wanted to switch to summer tires. But the company has had to say no, precisely because the law still requires winter tires as long as winter road conditions can prevail before March 31. He also remembers a previous season when about 50 drivers had to switch back to winter tires when spring was suddenly interrupted by new winter weather.
Those who drive with summer tires despite winter road conditions also risk fines. Since February 2025, the fine is 2,000 kronor for those who drive without winter tires when they are required.
It's not just about rules, but also about common sense. March can offer sun and dry roads one day, and frost or snow mixed with rain the next. If you switch too early, it can end with the car having to stand still or that you have to book another tire change.
For those who want to be on the safe side, the advice is simple: wait a little longer. Spring may be on its way, but it's not always entirely reliable.
