Retractable studs – new from Nokian
Nokian has introduced “the world’s first non-studded winter tyre where the driver can deploy tyre studs with the press of a button. Studs usually help tyre bite into snow, providing better grip. But on a bare surface they damage it and the sound is also a nuisance.
The Nokian concept makes it possible to retract the stud when not needed. The Finnish tyre maker has presented this concept as part of the celebrations to mark 80 years of winter tyres, which the company had introduced for the first time.
With the push of a button the little ice studs pop out and the tyre is as good as the Mach 5 on ice. Of course the button will eventually go away and the little studs will be tied to a real-time sensor mounted at the front of the vehicle that measures ice thickness and deploys these automatically.
