"...With an asymmetrical tread design, the tire has the traction capability on snow and ice of a winter tire as well as the ability to perform on wet and dry roads like an all-season tire.
The inside tread functions much like a winter tire. Higher sipe density provides more biting edges to increase traction on snow and ice, Toyo said. Additionally, the tire features snow claws to improve deep snow traction and slush grooves that provide increased traction on slush and snow.
In turn, the outside tread is built like an all-season tire, according to Toyo. Lower sipe density provides grip and traction for wet and dry roads, while the multi-wave sipe design also helps increase block rigidity, giving the tire better traction on icy, wet and dry road conditions, the tiremaker said. Snow claws are also present on the outside tread…"
