Nokian Tyres Launches Hakkapeliitta 01, the First Temperature-Reactive Studded Tire

A temperature-sensitive base compound deploys and retracts metal studs automatically without sensors.

Overview

  • Nokian says its Double Action Stud Technology delivers On-Demand Grip by switching studs between ON and OFF modes as temperatures change.
  • The tire carries the Three-Peak Mountain Snowflake and Ice Grip symbols indicating certified severe-winter performance.
  • The company claims up to 30% less road wear than its predecessor, up to 10% better ice grip, and about 1 dB lower noise.
  • Consumer sales are planned for autumn 2026 in North America, with pricing and independent test verification still to come.
  • Nokian traces the idea to a 2014 retractable-stud concept and reports thousands of prototype tests from its Ivalo Arctic center to the Hakka Ring in Spain.
