Wide, lateral notches are paired with circumferential Aqua Vac Channels to rapidly evacuate water away from the contact patch and enhance anti-hydroplaning features. This tire features Cooper's Snow Groove Technology which produces saw-tooth block edges on the exterior grooves for exceptional snow traction.
