The Nokian zLine summer tyre is stable, precise and quiet, precise and easy to manage even in extreme conditions. Excellent wet grip in all temperatures. The sporty Nokian zLine is a pro in demanding driving situations thanks to a new generation of tread compound, nanotechnology multi-ply construction and a surface pattern developed for fast driving. It responds immediately to steering movements, an absolute must when driving safely at the extreme limits. New Nokia Intelligent UHP Silica: improved wet grip and steering feel. The Nordic Intelligent UHP Silica wear surface compound is specially tailored for heavy-duty use at higher speeds. Operating ideally over a wide temperature range, the rubber compound improves wet grip both in the early mornings of early spring and in the dark of autumn. The feel on the road is perfect and unpredictable in all conditions. Surface pattern supports optimum handlingThe new and modern surface pattern perfectly supports the precise handling of a high performance tyre. Like other members of the Nokian family, the surface pattern is an asymmetric inside-outside design. The solid outer and inner shoulders are combined in block patterns, which are linked by longitudinal rows. The wide and massive stripes stiffen the tyre and reduce the movement of the pattern pieces in road contact. Deep diagonal grooves dominate the longitudinal ribs adjacent to the inner knuckle, providing stability when driving. At the same time, this new Hydro Grooves innovation effectively combats water transfer by storing water between the tread and tyre and directing it into the longitudinal grooves. This invention ensures a safe driving experience even in rainy weather. To counter the dangers of water transfer, the transverse main grooves in the outer shoulder were also designed with plunge grooves. More driving comfort and durability. The Nokian zLine's ride comfort is enhanced by the hemispherical holes in the longitudinal rib walls, which resemble the surface pattern of a golf ball. This Silent Groove Design innovation reduces interior and pass-by noise. The robust and durable Nokian zLine also drives convincingly on poorly maintained roads. The steel belt package combined with the double frame structure is made of extremely strong steel wire. For added safety, a redesigned belt guard protects the horn area of the rim. Revised groove depth gauge and information area. As usual, the tread is equipped with Nokia Tyres' patented DSI Driving Safety Indicator, which has been refined to the highest level of ease of use.
