Nankang Ice Activa Ice-1 is designed to reach high performance on snow and icy road conditions in Northern Europe.
With the design of centre rib and directional tread pattern that can strengthen the straight-direct stability and manoeuvrability on snowfield. With design of reticulate tread pattern groove that can strengthen the grip capability on snowfield.
Serrate 3D-SIPE at central part that can enhance the capability for ice-shovelling and snow-sweeping, as well as reinforce the rigidity of pattern block and stability of straight-direct.
Rectangular 3D-SIPE at shoulder area that can enhance the strength of pattern block and control the pattern block will not be over-deformed when wheeling or braking, hence to improve the safety of driving.
With design of irregular tack holes over the whole rim of tread pattern that can reinforce the friction and traction on ice road after installation of snow nails.
Optimized positions of stud holes over the tread pattern reinforce the friction and traction on icy road. Special silica formula is applied to improve the performance of the tyre when driving on icy or snowy roads.
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.
