Change Handle Based on Temperature

  • The Hakkapeliitta 01 studded snow tires change grip based on temperature.
  • These tires are equipped with “smart” studs that lengthen or retract.
  • The result is less road noise, less road wear and better grip.

Studded snow tires are an important feature for any car that drives in the coldest conditions. The best choice has long been Hakkapeliitta from Nokian. It grips well on ice, stops well in slippery conditions, and can cut through deep snow.

However, studded snow tires are not without problems. The studs worsen road wear and make loud noises when driving on pavement. Nokian has found the solution, and it’s pretty amazing: smarter tires that can automatically extend or retract their studs based on temperature.

The Nokian Hakkapeliitta 01 is the world’s first winter tire with on-demand grip. As the temperature of the tire changes, the stud stiffens and stays extended or loosens and goes deeper into the tire.

This action occurs thanks to a unique base layer embedded in the tire cap. This is where the pole is stuck into the rubber. As the tire gets colder, the studs remain stiff. However, as the tire heats up, the studs can be pushed deeper into the tread.

The result is a studded snow tire that is quieter, less harmful to the road surface, and still offers increased grip over other tire options—including previous versions of the Hakkapeliitta that did not feature this new technology.


Motor Pickup1: Any innovative news in the tire sector is interesting, but these latest tires from Nokian are truly interesting. The Hakkapeliitta 01 can automatically adjust grip based on temperature, while providing better grip levels than its predecessor. Nokian has created something truly amazing here.

While the market may be relatively small compared to other tire segments, there is still demand for tires with the aggressive Three-Peak Mountain Snowflake and Ice ratings. Nokian has once again proven why they are the best in the business in this segment.
