Nokian Rotiiva AT
235/70 R17 111T XL
- EU Tyre Label:
- Stable tyre with high performance on and off the road
- Aggressive tread pattern guarantees exceptional handling
- Sturdy structure, cut-resistant tread surface
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.
Since 1st November, 2012 all tyres made after 1st July, 2012 must show the European Tyre Label.
The European Union has developed this new provision to promote economic and ecological efficiency and ensure road safety.
Disadvantages The Tyre Label can provide an overview and give the customer more transparency, but it only covers three criteria. For an extensive evaluation of a tyre, however, far more performance characteristics are relevant. Especially in the search for suitable winter tyres the test results from different test institutions such as the ADAC are much more stringent.
We'd like to point out that it is the manufacturer that labels the tyre and provides us with this information. If you do not find the label values, either the manufacturer did not inform us of the label, or the product was manufactured before July, 2012. Before that date, tyres had not yet been required to carry a label, so in some cases it is possible to purchase a tyre without a Tyre Label.
The tyres are classified in terms of three performance characteristics:
• Fuel Efficiency (letters A to G)
• Wet Grip (letters A to G)
• External Noise
Finally, it is the driver that determines the fuel consumption. In order to reduce this over the long-term, by being careful during acceleration drivers can become more fuel-efficient and environmentally conscious.
Regularly checking tyre pressure helps to improve rolling resistance, reduces energy loss, and supports optimum adhesion in wet conditions. To reduce the risk of accidents and ensure your and the safety of other road users, always keep a reasonable distance.

The classification in terms of fuel efficiency is divided into seven classes, from the A-class (the highest) to G-class (the lowest). A tyre in the A-class consumes 0.1 litres less at 100km than a tyre in the B-class. An essential component for fuel efficiency is the rolling resistance or rolling friction.
Rolling resistance is the force that opposes motion. It is formed, for example, when a wheel is rolling. Rolling resistance depends not only on the geometry but also on the properties of the material.
Average Average value is between C-E. Class D is not used.
It shows how efficient the vehicle can brake on wet roads. Wet grip is an important feature especially with summer tyres. Class A has the highest safety and the shortest braking distances. Class F has low security and the longest braking distance.
The wet grip classes are based on test driving on wet roads with a speed of approximately 80 km/h. The difference between the braking distance of the tyres is 3-5 feet per grade. E.g., the difference in braking distance between Class A and Class F are up to 18 metres.
Average The average value of the tyres is between class B-E. Class D and G is not used.
The symbol indicates the external rolling noise in decibels and as a 3 class sound wave symbol to clarify whether the tire can keep the recommended level. External rolling noise does not correspond to tyre noise inside the compartment.
A continuous sound level above 80 decibel can cause health problems.
Three sound waves symbolize the worst results. These are the tyres that exceed the maximum limit of approval. A symbol of 2 sound waves have noise level that corresponds with the approved sound level. Tyres that are marked with 1 sound wave are over three decibel quieter than the approval.
