Dynamic semi-Kerf. Kerfs, which determine the tread block movement when a tire comes into contact with the road surface, are interconnected to help continuous tire deformation behavior which leads to enhanced comfort and handling. They also serve to supplement the tire behavior which is unstable in the initial stage and improves water drainage on wet and slush-covered roads.
Shoulder Step Groove. For SUV snow tires, ensuring consistent block stiffness leads to better handling performance and resistance against treadwear.
Square Profile. Offers maximized snow handling by adopting the square profile which applies the SCCT profile theory.
