Inside Tread: Higher sipe density for excellent traction on ice and snow. Outside Tread: Lower sipe density for traction on wet and dry roads.

Improves deep snow traction. Increases block rigidity for better ice and wet traction.

Evacuates slush for increased traction on slush and snow.

Minimizes irregular wear for a smooth, quiet ride. Improves braking on icy, wet and dry roads.
