“JLSB – Jointless Space Belt” in conjunction with the Nankang “Single Steel Winding System” is what Nankang calls the principle of the zero-degree steel belted carcass, which stands for the greatest stability in radial tires for motorcycles. Stability and greater stiffness of the carcass compared with the conventional use, for example of aramid belts, in carcass construction ensure the greatest possible stability in every driving situation, perfect feedback to the driver, confident handling, and optimal operating temperature of the tires. The profile design optimizes drainage for use in wet and rainy weather conditions. Front and rear tire profile are perfectly coordinated with each other to give the driver optimal safety when driving in the rain. The well conceived profile design is superior in aquaplaning conditions as well.
Easy handling, high mileage, perfect grip on wet surfaces, and in particular, safe behavior in various weather conditions are the requirements for motorcycle tires in the sport-touring class. The rubber mixtures used for the Nankang Roadiac fulfill the expectations of demanding, safety-conscious bikers.
The Nankang Roadiac uses one of the most modern two-component mixing technologies. It has thus far been necessary to choose between a motorcycle tire with a soft rubber mixture for a good grip and one with a more resistant mixture for a longer life. Thanks to the two-component mixing technology, the new Nankang Roadiac offers both in one tire. Through the use of a soft rubber mixture for the shoulders of the tire and a more resistant mixture in the middle, the new tire targets the specific needs of demanding motorcycle drivers. Using a soft rubber mixture for the shoulders of the tread improves traction and shortens the warm-up phase. On the front wheel, 20 percent of each shoulder surface of the tire consists of the softer rubber mixture, while at the rear wheel, twice as much of the tire footprint, 40 percent, has the softer rubber mixture to ensure optimal traction when accelerating from a banking angle. In the center of the tire, especially resistant rubber mixtures are used that are optimally suited to transfer driving and braking forces and guarantee a long life. The center of the front tire has 60 percent and the rear tire 20 percent of the harder, more resistant rubber mixture.
The new Nankang Roadiac is thus a sport-touring tire with a wide range of uses and an unbeatable price-performance ratio in this class.
