Retains its accurate driving properties in high speed driving
Excellent safety on wet roads
The sporty Nokian zLine is a professional in demanding driving conditions, thanks to its new generation of tread compound, nanotechnology layered structure, and tread pattern developed for fast driving. It immediately responds to steering, which is an essential requirement for safe operation at extreme limits.
The new Nokian Intelligent UHP Silica: lower heat generation, better wet grip
The Nokian Intelligent UHP Silica tread compound developed for Nokian zLine was specially tailored for demanding use at higher speeds. The new UHP tread compound was refined to have extremely low heat generation, maximising the available mileage and ensuring good structural integrity. The rubber compound works ideally along a wide temperature range, thereby improving wet grip that drivers will truly appreciate. The feel of the road is perfect and provides no surprises under any conditions.
Tread pattern supports optimal handling The new, modern tread shape of the Nokian zLine perfectly supports the precise driving feel of this high-performance tyre. As in the other Nokian summer tyres designed for fast driving, the tread is of an asymmetrical inside-outside pattern. The rigid inside and outside shoulder area connects with block patterns that are bound together by longitudinal ribs. The wide, massive ribs stiffen the tyre and reduce the movement of the pattern blocks during road contact. The longitudinal ribs next to the inner shoulder are dominated by deep lateral grooves that stabilise handling. At the same time, this new Hydro Grooves innovation effectively prevents aquaplaning by storing water from between the surface and the tyre, and by guiding the water into the longitudinal grooves. The innovation ensures a safe driving feel, even in the rain.
To combat aquaplaning, separate Swoop Grooves were also shaped in the transversal main grooves on the outer shoulder. More driving comfort and durability The semi-circular indentations, reminiscent of a golf ball, on the walls of the transversal grooves provide additional driving comfort for the Nokian zLine.
This Silent Groove Design innovation reduces the interior noise and external rolling noise of the vehicle. Even motorists who are used to higher speeds can rely on the Nokian zLine for years of service, even as the tyre gets older and wears down. The extremely stiff steel belt pack, designed for fast Central European roads and combined with a double body structure, is made of high-strength steel wire. The tough, durable Nokian zLine is sure to work well even on poor road sections. A new rim guard provides additional protection for the edge of the rim.
EU Tyre Label and Efficiency Classes
The European Union has introduced the EU Tyre Label by Regulation (No. 1222/2009) identically and bindingly for all EU member states. It applies to passenger car tyres, light commercial vehicle tyres and heavy commercial vehicle tyres produced after 01.07.2012.
Three different areas are tested: rolling resistance, wet grip and the rolling noise the tyre makes on the road.
The following are not affected by the EU Tyre Label: retreaded tyres, professional off-road tyres, racing tyres, tyres with additional devices to improve traction such as spiked tyres, T-type emergency tyres, special tyres for fitting to vehicles first registered before 1 October 1990, tyres with a maximum authorised speed of 80 km/h, tyres for rims with a nominal diameter of 254 mm or less or 635 mm or more.
With this regulation, the European Union is pursuing the goal of promoting economic and ecological efficiency in road traffic as well as increasing road safety on the one hand, and on the other hand, granting consumers more product transparency and at the same time serving as an active decision-making aid.
Already during the incorporation, experts criticise the fact that the EU Tyre Label unfortunately only shows a few product characteristics. Apart from rolling resistance, wet grip and rolling noise, which are the main focus of EU tyre labelling, tyres have much more important and safety-relevant product characteristics, such as aquaplaning properties, driving stability, service life, braking properties on dry and wet roads, behaviour in wintry conditions, etc.
Tyre manufacturers point out that test results from various institutions and journals remain an important information medium for the end consumer. These tests usually focus on further safety-relevant product characteristics besides the EU standard qualifications for tyre labelling, which are always important for the final customer.
