Nokian TSF00036 Hakkapeliitta 01 Studded Winter Tire with Double Action Stud Technology

The Nokian Hakkapeliitta 01 is a groundbreaking studded winter tire that automatically adjusts its stud grip in response to changing temperatures — delivering maximum ice traction when you need it most and reduced road contact when conditions improve. It is the world's first studded winter tire of its kind, representing a fundamental leap forward in cold-weather tire engineering.

Double Action Stud Technology

At the heart of the Hakkapeliitta 01 is Nokian's patented Double Action Stud Technology. The studs are embedded in an adaptive base compound — an inner layer of specialized rubber that softens in warmer temperatures (above 41°F), allowing the studs to retract below the tread surface. When temperatures fall below 23°F, the compound firms up, pushing the studs back into active contact with the road. This means the tire operates in Studmode ON for icy and snowy conditions and Studmode OFF on bare pavement — automatically, with no driver input required.

Key Features:

• Double Action Stud Technology: Studs automatically extend in cold and retract in warm conditions for on-demand ice grip
• Double Stud Design: Two distinct stud types optimized for straight-line braking and cornering on ice and packed snow
• Up to 30% Less Road Wear: Adaptive stud retraction significantly reduces road surface abrasion compared to traditional studded tires
• Up to 10% Better Ice Grip: Improved ice braking performance over its predecessor, with up to 5% better wet grip
• Ice Grip Emblem Certified: Meets the 18% ice braking improvement threshold for Ice Grip certification
• Three-Peak Mountain Snowflake (3PMSF) Rated: Certified for severe snow service conditions
• Aramid Strong Sidewalls (select sizes): Aramid fiber reinforcement provides exceptional resistance to impacts from potholes, curbs, and road debris
• SilentDrive™ Technology (select sizes): Absorbs disruptive noise frequencies for a quieter, more comfortable ride on all surfaces
• Electric Fit™ Compatible: Engineered for seamless performance on electric and hybrid vehicles
• Optimized Stud Geometry: Precision stud placement ensures ideal contact angles on glassy ice, packed snow, and transitioning wet pavement

The Hakkapeliitta 01 is built for passenger cars, SUVs, and EVs, and is available in rim sizes ranging from 14 to 22 inches. From the brand that invented the winter tire in 1934, the Hakkapeliitta 01 delivers a new standard in winter safety, sustainability, and driving comfort.
