HANKOOK K117A Ventus S1 evo2 SUV is a summer tire with an asymmetric tread pattern for high-performance 4x4 SUVs and SUVs. The model belongs to the Ultra High-Performance class and appeared for the first time in retail in the spring of 2014. The South Korean manufacturer says the Ventus S1 evo2 SUV, specially designed to meet the needs of this popular vehicle category, combines sportiness with comfort, low noise, and reduced rolling resistance. Safety features such as tire grip on wet surfaces have also been specifically tailored to the requirements of premium SUVs, many of which are already equipped with these tires as original equipment (OEM).
For example, Hankook supplies high-performance tires from the award-winning Ventus range for popular German cars such as the Mercedes-Benz GLC and GLC Coupé. The German premium car manufacturer's latest-generation mid-size crossovers will be fitted with Ventus S1 evo2 SUV tires at the factory. For Mercedes-Benz GLC vehicles, Hankook supplies tires in sizes 235/65 R17 V MO and 235/60 R18 V MO. During the test phase, the 18-inch version of the tire had a particularly low rolling resistance and was therefore selected by Daimler AG as an OE tire for EU markets with special CO2 emissions requirements. Also, the sports version of the Mercedes-Benz GLC Coupé is now equipped with 19-inch tires of various sizes in the sizes 235/55 R19 Y MO (on the front axle) and 255/50 R19 Y MO (on the rear axle), which corresponds to the high-speed dynamic characteristics of the coupé.
“The superior performance of our products demonstrates our ability to provide the market with Hankook's cutting edge technology and the highest quality for all premium vehicles: commercial vehicles, passenger cars, and the popular SUV segment,” explains Ho-Yul Pae, Head of Hankook Tire Europe. ... “We are particularly proud that the original tires for Daimler AG, including the Mercedes-Benz GLC and GLC Coupé, are developed in collaboration with our R&D center in Germany and produced exclusively in our best manufacturing facility in Europe.”
Ahead of the start of sales, the HANKOOK Ventus S1 evo2 SUV received a very good rating in a tire test conducted by the German automotive magazine Gute Fahrt. The specialists of the publication paid tribute to the excellent combination of sports performance with safety, comfort, and environmental friendliness.
Independent tire tests by the automotive magazine Gute Fahrt (March 2014) compared ten summer SUV tires in the size 235/55 R17. The HANKOOK Ventus S1 evo2 SUV summer tires not only received the highest overall expert rating, including recommendations for sale but also became the only tire to perform better in wet tests (wet braking, longitudinal and diagonal aquaplaning). The rating "very good" was also awarded for the very high level of comfort and especially the low noise level.
The sophisticated technology used in the Ventus S1 evo2 SUV, with a multi-radius tread and a double-layer rayon fiber casing, ensures maximum contact patch area in all conditions. The tire impresses not only with its outstanding aquaplaning characteristics but also with its optimal grip on the surface, which ensures the perfect balance on wet and dry surfaces. In addition, the handling and safety performance when driving at high speeds has been significantly improved.
The state-of-the-art silicon compound increases grip on wet surfaces with reduced rolling resistance and improves the environmental friendliness of the tire. Improving the wear resistance and thermal aging resistance of the tire also contributes to the increased mileage and service life of the tire. The advanced cooling system of the high-tech tire also provides faster heat dissipation for improved handling and durability.
You can buy HANKOOK Ventus S1 evo2 SUV tires in the Bai Wheels online store. A large number of standard sizes for rims with a landing diameter from 17 to 22 inches will allow you to choose tires for almost any car.
HANKOOK K117A Ventus S1 evo2 SUV design features:
Short braking distances and excellent grip on wet road surfaces ensure that the driver can always rely on their tires. The Ventus S1 evo2 SUV's advanced Multi-Tread-Radius technology and two-layer rayon casing ensure an optimal contact patch even if it is suddenly necessary to turn around or complete Autobahn braking in urban traffic conditions in the rain. This optimized wet grip is achieved through an innovative silicon styrene polymer blend in the tread.
Features of the tread pattern of the HANKOOK K117A Ventus S1 evo2 SUV:
The summer tire HANKOOK K117A Ventus S1 evo2 SUV received several innovative technical solutions at once, which significantly improved the balance between grip characteristics on dry and wet roads, which, by the way, was good for the last generation model. In addition, this tire has a marking that fully complies with the recently adopted EU requirements.
Multi-Tread Radius and updated rubber compound
One of the technical innovations in the HANKOOK K117A Ventus S1 evo2 SUV is the Multi-Tread Radius technology, which has proven to be effective on DTM tires. Thanks to her, it was possible to obtain an almost rectangular shape of the contact spot (in the figure on the left). In this case, external pressure is distributed over it very evenly, even with significant lateral acceleration. This made it possible to achieve reliable and stable handling both on dry and wet surfaces, and most importantly, improved control over the car moving at high speed.
As befits the flagship of the entire model range, the summer tire HANKOOK K117A Ventus S1 evo2 SUV received a completely new rubber compound (in the picture on the right), the composition of which is distinguished by the presence of the latest generation of silicon-containing components. Their key feature is an optimized system of cross-linking between molecules, thanks to which it was possible to increase tensile strength and improve abrasion resistance. Besides, the new silica has improved the resistance of the rubber compound to high temperatures. Another innovation in the composition of the compound was a special styrene polymer, which significantly improved wet grip while reducing rolling resistance.
Three-layer block construction
Borrowed from the DTM, an innovative three-layer tread design and a special stepped shoulder block arrangement increase the contact pattern of the HANKOOK K117 Ventus S1 evo2 SUV summer tire with the road as it wears away, thus guaranteeing more effective grip throughout the entire service life.
Cooling system
Civilian tires, like racing tires, do not tolerate high temperatures quite well. To reduce the heating of the tire while driving, South Korean tire workers have placed special spiral Cooling Fin "fins'', as well as two-stage grooves (in the picture on the right) at the bottom of the drainage grooves. This made it possible to create additional air turbulence, thanks to which it was possible to establish a more efficient heat dissipation. As a result, the K117 Ventus S1 evo2 SUV demonstrated a significantly longer service life. In addition, the sidewalls of the tire have received the so-called "aerodynamic" design, which helps to reduce the noise level.
