- Directional tread design improved snow acceleration and water evacuation. - Patented circumferential snow-groove technology enhances snow-on-snow grip capabilities. - High sipe density design increases biting edges for improved ice and wet traction capability. - High-silica, low modulus tread compound adds superior ice, slush and wet grip even in extreme, cold temperatures. - Micro-gauge sipes provide more stable tread elements when braking and increases the number of biting edges.
