The Optimo H418 features a special tread compound molded into a symmetric pattern with independent tread block design that gives high grip on both wet and dry roads, for an all-weather performance. The solid center rib improves handling and ensures even wear, while the closed shoulder slots provide responsive steering and reduced noise levels. The open circumferential grooves help evacuate water from the tread to prevent hydroplaning and deliver better wet performance. The high density kerf design offers additional biting edge for enhanced grip in snow and ice. The internal construction of tire comprises twin steel belts for stabilizing the tread area and additional polyester cord body ply to reduce on road vibrations as well as provide high ride comfort.
