Dunlop Signature Grand Touring Tire. Signature tires share technology with Dunlop's ultra-performance tires and still deliver the touring ride and feel. "Multi Pitch Tread Design technology is for driver and passengers alike. Varied sizes of tread blocks arranged in a diverse pattern create sound frequencies that cancel each other, helping to make the ride quiet. A stiffer high-performance all-season tread compound helps deliver outstanding tire performance at highway speeds. Improved bead seat technology helps deliver a tighter fit between the tire and wheel for a noticeably better ride. Signature also features JointLess Band technology that helps maintain the tire's smooth performance at highway speeds, uniformity and long treadwear. VersaLoad Technology optimizes the tire footprint on the roadway for consistent handling, ride comfort and treadwear under various loading conditions.
