Nankang Sportnex AS-2+ Tire: Superior Performance and Safety
Unmatched Wet Handling and Drainage
The Nankang Sportnex AS-2+ tire is engineered to enhance your driving experience with its advanced design features. The tire's inner and outer sides boast a pore ratio of 38% and 34%, respectively, significantly improving water drainage and wet road handling. This ensures superior grip and control even in challenging weather conditions.
Innovative Design for Enhanced Stability
With a widened circumferential groove, the cross-sectional areas of the inner and outer grooves have been increased by 21.3% and 43.8% compared to conventional designs. This expansion allows the tire to accommodate more water, enhancing its drainage performance and ensuring a safer drive on wet roads.
Advanced Tread and Sidewall Construction
The Nankang Sportnex AS-2+ features a completely new tread design and reinforced sidewalls, increasing the tire's rigidity for improved stability and durability. The serrated wall of the circumferential groove efficiently channels water away while reducing noise generated by air flow and groove wall friction.
Optimized for Reduced Noise and Increased Comfort
To further enhance driving comfort, the tire employs a beveled design for the lateral grooves on the tread shoulder. This optimization reduces rolling noise and effectively improves block stiffness, ensuring a quieter and more comfortable ride.
Experience the perfect blend of performance, safety, and comfort with the Nankang Sportnex AS-2+, designed to meet the demands of modern passenger cars.
The void ratio of the inside and outside are respectively 38% and 34%, and it can improve tyre’s drainage efficiency and also wet handling.
With broadened circumferential groove width, the section area of inside/ outside grooves is increased 21.3% and 43.8% respectively compared to the conventional design. And it can increase the volume to contain more water for better drainage performance.
Brand new profile design and reinforced sidewall design can upgrade tyre stiffness.
Serrated wall of circumferential groove: Discharge water in the circumferential grooves promptly and effectively, as well as reduce the noise caused by the friction between airflow and groove wall.
For inside and outside lateral groove on tread shoulder, we use chamfering design to optimize the angle of lateral grooves, and it can reduce tyre’s rolling sound and improve block stiffness effectively.
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.
