The new Nokian Rotiiva AT (All Terrain) rolls effectively both on and off the road. This sturdy, special tyre guarantees optimal performance without compromising safety or driving comfort. It completes the versatile SUV and 4x4 range from Nokian Tyres. Rotiiva AT is excellent on asphalt or gravel, but also moves with ease in lighter off-road conditions. The sturdy structure and tailored, cut-resistant tread compound give the tyre excellent durability when used with heavier cars, as well. The comprehensive selection of sizes is aimed at light trucks, larger SUVs, and pick-ups. The aggressive tread pattern of the new product, and especially its wide, polished grooves maximise grip and handling in rapidly changing summer conditions. Thanks to a unique tread pattern, the tyre also cleans easily and runs effortlessly on a soft platform.
Steady going: The smooth, fluent driving is boosted by the centre rib stabilisers that stiffen the tyre. The driver feels this in the excellent driving stability and quick steering response. More stability is added by the 3D sipes that actively bind the pattern blocks together upon road contact. The heavily siped pattern block sections support each other. Unnecessary sipe movement stops, which further improves handling. Cooling ribs in the shoulder area improve the durability of the Rotiiva AT, which is a tyre that enjoys poor roads and suddenly changing conditions. Lower heat generation means slower wear, more comfortable driving, and more mileage. Stone ejectors on the bottoms of the grooves minimise the penetration of sharp rocks into the tyre. The stone ejectors further increase the operating life of the tyre by preventing tyre body damage, especially when driving on uneven surfaces.
Tailor-made style and safety: The side surfaces of this eye-catching and massive product are different. This means that you can tailor the outlook to suit your tastes upon installation: a more rugged appearance for off-road terrain, and a more stylish and toned-down look for the road. Nokian Tyres' patented Driving Safety Indicator on the tread surface improves safety and driving comfort. Retail sales of this sturdy and versatile new product will begin in the spring of 2012 on Nokian Tyres' core markets.
ARAMID SIDEWALLS – Robust like never before
Nokian tyres with Aramid sidewall technology offer you additional security and durability for demanding weather conditions and rough roads. Their incomparably strong sidewalls are exceptionally resilient to wear and cuts. The Aramid fibres stiffen and strengthen the sidewall, enabling it to withstand blows and cuts even better.
The same material is also utilised in the aviation and armour industries. It is also used successfully in bulletproof vests.
Aramid protects the Nokian tyres. The Nokian tyres protect lives.
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.
