WI NTERTIRE With optimized angle, 3D twisty sipe pattern design ensures the rigidity of pattern block, at the same time, enhances the grip and effectively prevents slipping on ice and snow. Wide shoulder pattem design enhances the handling and stering performance. Herringbone tread design and coherent circumferential pattern rib not only improve grip but also ensure lateral handling performance on ice and snow. Three longitudinal grooves, with excellent drainage performance, effectively pre-vent lateral slipping on ice and snow.
