This compound is molded into a symmetric tread design with tie-barred shoulders, intermediate ribs and center blocks for dry road tracking and traction. Four circumferential grooves help water flow from under the footprint to resist hydroplaning and enhance wet traction while numerous notches and sipes increase the edges that bite into light snow.The tire's internal structure includes twin steel belts reinforced by spirally wrapped nylon on top of a polyester casing to blend ride comfort and durability.*Specific sizes featuring BluEarth technology are identified as such on the sizes tab, as well as on the tire's Specs tab.
