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.
The Tire Labeling Ordinance specifies the information requirements on fuel efficiency, wet grip and external rolling noise from tires. In addition, reference is made to the winter properties of the product.
The EU 1222/2009 regulation that has been in force since November 1st, 2012 has been revised and will be replaced by regulation EU 2020/740 from May 1st, 2021; From this point on, new requirements apply. The rating classes for fuel efficiency, wet grip and exterior noise have been changed and the layout of the EU label has been adjusted. The manufacturer's product data sheets stored in the EU database can be downloaded via a QR code integrated into the label. Information on snow grip and ice grip is also newly included for tires that meet these criteria.
The following tires are exempt from the regulation: - tires that are designed exclusively for installation on vehicles that were first registered before October 1, 1990 - retreaded tires (until a corresponding extension of EU VO 2020/740 has taken place) - professional off - Road tires - Racing tires - Tires with additional devices to improve traction, eg studded tires - T-type emergency tires - Tires with a permissible speed below 80 km/h - Tires for rims with a nominal diameter ≤ 254 mm or ≥ 635 mm
The criteria and evaluation classes at a glance
fuel efficiency
The fuel consumption depends on the rolling resistance of the tyres, the vehicle itself, the driving conditions and the driving style of the driver. The measured rolling resistance (rolling resistance coefficient) of the tire is divided into classes A (highest efficiency) to E (lowest efficiency).
If a vehicle is completely equipped with class A tires, a consumption reduction of up to 7.5%* is possible compared to class E tyres. In the case of commercial vehicles, it can even be higher. (Source: European Commission Impact Assessment * when measured according to the test methods set out in Regulation (EU) 2020/740)
Please note: Fuel consumption depends to a large extent on your own driving style and can be significantly reduced by driving in an environmentally friendly manner. Tire pressure should be checked regularly to improve fuel efficiency.
wet grip
Wet grip is divided into classes A (shortest braking distance) - E (longest braking distance).
If a car is equipped with class A tires, compared to class E tires, a braking distance of up to 18 m can be reduced when braking from 80 km/h (on a road surface with average grip).* *Source: wdk Economic Association of the German Rubber Industry eV
Please note: Traffic safety depends to a large extent on your own driving style. The stopping distances must always be observed. Tire pressure should be checked regularly to improve wet grip.
External rolling noise
The noise emitted by a tire affects the overall volume of the vehicle and affects not only your own driving comfort, but also the noise pollution of the environment. In the EU tire label, the external rolling noise is divided into 3 classes from A (lowest rolling noise) - C (highest rolling noise), measured in decibels (dB) and compared with the European noise emission limit values for external tire rolling noise.
A The pictogram with the classification "A" indicates that the tire's external rolling noise is more than 3 dB below the EU limit value in force until 2016. B The "B" classification means that the tyre's external rolling noise is up to 3 dB below or equal to the EU limit value in force until 2016. C The classification "C" indicates that the specified limit value is exceeded.
