The asymmetric tread pattern features a high density siping detail that promotes firm grip in all weather. The ribs and tread blocks of the inner side of the tire provide additional biting edges for winter weather traction with their advanced siping design. The four special circumferential grooves, three wider and one narrower, excellently prevent hydroplaning situations by eliminating water from beneath the tire footprint. The siping design and water evacuating ability ensure a safer year round driving experience.
