The Cooper Discoverer True North Winter Tire is ideal for daily commuters who drive on plowed and treated roads and deal with slush and black ice throughout the winter months. Made to have high wet traction for slush covered roads, but extremely quiet and maintains a superior grip on ice and snow. Designed with Cooper's "Snow Groove technology", patented saw-tooth tire patterns that trap snow in the tread to provide superior snow-on-snow traction. The tread is made with coupled silica compound which enhances the tire's traction on ice and negates the need for stud pins
