A new summer tyre for top-speed driving
Nokian Z is a tyre for top-speed driving that combines excellent wet grip, precise controllability and clean rubber compounds. The design of the tyre has concentrated on safety under extreme situations and environmental friendliness.
The layer beneath the tread compound reduces rolling resistance and heat emission and strengthens the tyre’s structure. The tyre wears evenly and maintains its good properties throughout its useful life.
The acoustically optimised tread pattern and the noise cavities of the main grooves dampen tyre noise, making it pleasant.
With its extremely good wet grip, the rubber compound on the shoulder areas provides more effective grip when braking and cornering and ensures safety in extreme situations.
EU Tyre Label and Efficiency Classes
The European Union, under CE 1222/2009, has mandated that all tyres manufactured after the date of July 1 2012 for cars and commercial vehicles include standard EU Tyre Labels classifying them by three performance characteristics:fuel efficiency classified from A to G,wet grip classified from A to G, and noise emission in decibels.
Categories of tyres unaffected by this regulation include: retreaded tyres, professional off-road tyres, racing/sports car tyres, as well as certain types of tyres designed to improve traction such as studded tyres, T-type temporary spare tyres, tyres for cars built before 1990, tyres with a maximum allowed speed of 80km/h, tyres for rims with a diameter less or equal to 254 mm or greater or equal to 635 mm.
This label is intended on one hand to promote economic and ecological efficiency in traffic, as well as increase road safety, and on the other hand to help consumers select appropriate tyres by ensuring a certain degree of product transparency.
Nevertheless, the label has been criticized for only showing a very limited number of characteristics. Professionals argue that tyres have many more features that are important and relevant to road safety, including but not limited to aquaplaning properties, driving stability, service life, product properties on wet and dry roads other than wet grip, properties on snow.
Tyre manufacturers suggest that the test results from various institutions and industry magazines should remain a very important source of information for the end consumer, because they focus on and rate a wide variety of tyre properties and features.
