Winter can be unpredictable and hazardous, but your tires should not. The Nokian Tyres Hakkapeliitta R5 EV covers all northern winter conditions and performs predictably on bare, wet, icy and snowy roads. A Double Block Grip design offers superior grip and handling, while excellent ice performance is guaranteed by unique Arctic Grip Crystals. Microscopic crystals work like built-in studs. As the tire wears down, the crystals emerge and activate a grip reserve to help keep you safe on your journeys.
