After more than a decade of development, Nokian has solved one of winter driving's oldest frustrations: studs that grip ice in freezing conditions but don't shred asphalt when it warms up. The Finnish manufacturer's new Hakkapeliitta 01 tires automatically extend metal studs as temperatures drop and retract them when conditions improve—no seasonal tire swaps, no chains, no manual fiddling.
The problem these tires tackle is real. Traditional studded tires are brutal on road surfaces during warmer months, which is why many regions ban them outside winter. Summer tires offer no grip on ice. Drivers in cold climates have long faced an awkward choice: swap tires twice a year, deal with chains, or accept worse performance during the season that matters most.
How cold becomes grip
The technology relies on temperature-sensitive materials embedded in the tire's structure. Nokian calls it "Double Action Stud Technology"—three material layers work together so that the innermost layer stiffens when temperatures drop, pushing metal studs to the tire's surface where they can bite into ice. When the road warms, that layer softens again, allowing studs to retract safely back into the rubber.

What's new is the material system that controls whether they're exposed or hidden. Deployment and retraction happen quickly enough to respond as you drive through changing conditions—though Nokian hasn't disclosed exact timing, likely because it varies with ambient temperature and road conditions.
The real significance here isn't just the engineering—it's that this eliminates a friction point many drivers never questioned because they had no alternative. For someone in Minnesota or Sweden, the Hakkapeliitta 01 means one set of tires handles your entire year. No spring and fall tire changes. No storing a second set. No wondering if you switched too early and hit unexpected ice.
Compared to Nokian's flagship Hakkapeliitta 10, the new model delivers up to 30% less road wear (meaning less damage to asphalt during warm months) and 10% greater ice grip. It also features an optimized tread pattern for ice, Aramid sidewalls for impact protection, and an improved compound for better overall handling. Nokian is launching the Hakkapeliitta 01 in 124 sizes from 14 to 22 inches, covering most cars and SUVs.
The tires arrive across Europe and North America in late 2026. One caveat: studded tire regulations vary by region and season, so you'll need to check your local rules before buying. But for regions where they're legal year-round, this shifts the entire calculus of winter driving from a seasonal hassle to something you set and forget.
