- The CS4 is constructed using variable density nylon technology - Nylon is strategically placed to resist flat spotting which improves ride quality and promotes even tread wear for a long tire life - The innovative 4-rib, all-season tread design incorporates numerous features to provide excellent stability, traction and tread wear - The chemically coupled silica and carbon black compound allows for superior wet traction without sacrificing tread wear - An optimized polymer matrix allows the compound to remain pliable at lower temperatures while contributing to lower rolling resistance - This premium tire features tapered circumferential sipes that allow for optimal water evacuation from the tread area, increasing traction in the rain or snow
