OSTERSUND, Sweden—Continental A.G. is developing a rubber-coated tire stud that it claims can deliver greater ice grip while reducing the negative impact on dry road surfaces.
Conti claims the rubberized spike—which could be market-ready within three years—can deliver up to 7 percent greater grip on ice while reducing road wear by as much as 20 percent and cutting down on noise generated by a spiked tire.
Developed by Conti engineers in-house, the rubberized stud features a flexible rubber body molded around the metallic spike, a design element that Conti claims allows the spike to penetrate the ice deeper than a stud without the rubber shielding.
This in turn generates higher forces and added grip, as does the rubber-on-ice contact.
Conti's work on this and other stud design improvements of the last few years was aided by its 2008 acquisition of Tikka Spikes Oy, a Tikkakoski, Finland-based producer of tire studs, a company spokesman said.
Conti discussed this development at its recent "Vision Zero goes North" TechnikForum in Ostersund, where it also unveiled a pair of winter tires developed for the 2018-19 winter season — the Winter Contact TS 860 S and Viking Contact 7, neither of which is slated for sale in North America.
