The Sport Maxx RT (inspired by Racing Technology) is Dunlop's Max Performance Summer road tire developed for the drivers of sports cars, sporty coupes and high performance sedans. Dunlop Racing Technology combines sophisticated tire materials and manufacturing techniques to enhance road feedback and driving precision. Like all summer tires, the Sport Maxx RT is not intended to be driven in near-freezing temperatures, through snow or on ice.Sport Maxx RT tires feature adaptive compound technology that uses motorsports derived polymers to allow its silica-plus tread rubber to adapt to the textures of the road surface, maximizing road contact and increasing grip. This compound is molded into an asymmetric design that features large outboard shoulder blocks tied to a notched intermediate rib that enhances dry road responsiveness and cornering control. A continuous center rib and notched inboard intermediate and shoulder ribs are separated by wide circumferential grooves to resist hydroplaning and enhance wet traction. Dunlop Multi-Radius-Tread Technology distributes footprint pressure effectively across the tire and allows the footprint shape to change more smoothly as it moves from a straight to a curve, leading to better control and more precise driving.The tire's internal structure includes twin steel belts reinforced by Dunlop's JointLess Band (JLB) spirally wound cord to provide high-speed durability and enhance ride uniformity. Limited sizes of the Sport Maxx RT are available with Dunlop's Noise Shield Technology, which involves the manufacturer adhering a layer of sound-absorbing foam to the inner liner of the tire to reduce cabin noise in the vehicle. These sizes are identified on the Specs page and in the search results. Related Information: Noise Reducing Tire Technology
