Nokian extendable studs

Studded snow tires are a rarity in the US today. Many drivers opt for all-season tires for the entire winter, and those that don't generally buy studless snow tires. In many states, studded tires are only permitted during a specific period of the year or even only when the road is snow-covered because they cause added wear to bare roads. But Finnish tiremaker Nokian thinks it has created the perfect solution.

Nokian has created a concept tire with electrically extendable studs that are controlled inside the vehicle. It's based on the tread pattern and structure of Nokian's Hakkapeliitta 8 SUV studded winter tire. At the press of a button, the studs on all four tires raise or lower. This gives drivers the extra traction of studded snow tires when needed but, retracts back into the tire to save the added wear on the road.

The company thinks that it may be able to have these tires on the road one day, and it would give more drivers the option to have the extra snow-plowing traction of studs when necessary. Scroll down to see them in action on a Porsche Cayenne and read the press release.

Nokian Tyres: The world's first non-studded winter tyre with studs

Unique stud technology brings the studs out when they are needed

Nokian Tyres presents the world's first non-studded winter tyre with studs in connection with the 80th anniversary of the winter tyre. With this revolutionary concept tyre and its unique stud technology the inventor of the winter tyre gives a hint of the things to come in the future. With a press of a button, the driver can bring out the studs to improve the grip of the tyre. When the studs are not needed, they can be retracted back into the tyre.

The idea of the combined non-studded and studded tyre is that the driver can make the switch when the conditions clearly change. Studs are not used on dry roads and stable winter conditions, but they can be activated in icy weather for extreme safety.

The concept tyre of the world's leading winter tyre specialist utilises the tread pattern and structural solutions of the newly introduced Nokian Hakkapeliitta 8 SUV studded winter tyre. The studs on all four tyres raise and lower at the same time. The body of the stud remains in place, and the moving part is the hard metal pin in the middle of the stud.

- This new concept tyre is an amazing technological feat. The unique stud concept may indeed become a reality one day. As the pioneers of the winter tyre world, we show that it is possible to combine a studded and non-studded winter tyre, says Matti Morri, Technical Customer Service Manager for Nokian Tyres.

Nokian Tyres developed and manufactured the world's first winter tyre to match the Northern frost in 1934. Two years later, the engineers at the tyre factory came up with an improved solution for passenger car drivers struggling with the slippery winter roads, and they called it the Snow-Hakkapeliitta. Nowadays, the Nokian Hakkapeliitta is one of the world's best-known winter tyre brands.
