Nokian Z G2 - Test winner of Auto Bild and numerous other magazines! The fast-driving Nokian Z G2 stands out from the rest in its class: it handles demanding and difficult conditions far better than its competitors. Safe and durable, the Nokian Z G2 is unaffected by extreme temperature fluctuations, unafraid of ruts, rain, rough asphalt and uneven road surfaces. Cool Zone Concept is precise, accurate and stable. Designed for demanding conditions, the performance of the Nokia Z G2 was raised to the top of its class by applying the latest technology in development and production. The key Nokia Cool Zone Concept innovations of multi-ply tread construction, nanosilica compound and new surface geometry make the Nokia Z G2 unique. The bottom layer of the multilayer structure is a thin layer of rubber compound to reduce rolling resistance and heat build-up. The middle layer uses the latest nanotechnology. The flexible nanosilica mix in the middle layer responds to steering movements more quickly than a conventional rubber mix. The road contact becomes sensitive and precise. The new Nordic Cool UHP Silica compound developed for Nokia's Z G2 ensures excellent wet grip at all temperatures. New geometry for excellent handling. The redesigned tread pattern of the Nokian Z G2 improves driving stability, especially in cornering, lane changes and evasive manoeuvres. It makes the Nokian Z G2 safe and precise to handle, even in extreme situations.In terms of appearance, the Nokian Z G2 is clearly a member of the family: like the other members of the Hakka family, the surface design is an asymmetrical inside-outside design. Like the other Hakka tyres, this is a sporty UHP tyre. Designed for sports cars and fast driving, the Nokian Z G2 represents the UHP category, the toughest category of passenger car tyres. Features.
