The Nankang AS-1 is a all-season tire specially designed for drivers who seek reliable performance, year-round traction, and comfort. Ideal for passenger cars, the Nankang AS-1 delivers great performance on both wet and dry weather. It features an asymmetric tread pattern which blends dry grip and wet traction. Notice the tread pattern chance across the tire™s face. This allows the Nankang AS-1 to provide its dual performance. The inside works and middle part is for traction during wet and winter weather while the outside are large tread blocks which provide cornering capability on dry road surfaces. Sidewalls on the Nankang AS-1 are marked with the appropriate labels to ensure that you position the tire™s correctly. Because the Nankang AS-1 has an asymmetrical tread pattern, you can use many different rotation patterns when driving it. Helping it look more rigid and wear longer is the shoulder™s unique straight groove.
