Navigating through ice and snow can be a stressful ordeal for even the most seasoned driver. Fortunately, winter tires are designed to give drivers added traction and control on wintery roads, and Nitto built the NT90W to assist drivers during the colder months. Walnut shells act like mini-studs thanks to their ability to scratch and dig into ice and snow, and bamboo charcoal within the NT90W soaks up water on icy roads like a sponge. 3D Multi-wave and 3D Interlocking sipes create a stable handling performance, and the NT90W's dual zone rubber compound helps drivers with acceleration, braking, and handling on wintery roads.
