The Sumitomo HTR A/S P02 (High Tech Radial, All-Season, Premium 2nd Generation) tire line includes W-speed rated Ultra High Performance All-Season radials developed to meet the year-round driving needs of sports car, sporty coupe and performance sedan drivers by blending dry and wet road performance with all-season wintertime traction. The HTR A/S P02 radials use Sumitomo's high-tech materials and manufacturing methods to blend ultra-high performance with all-season traction, even in occasional light snow.The HTR A/S P02 radial's all-season silica-enhanced tread compound is molded into an asymmetric pattern that promotes wet traction and even wear. Notched shoulder blocks backed by outboard circumferential ribs enhance dry road cornering and stability. Water evacuation channels and high-angle lateral grooves reduce the risk of hydroplaning and enhance wet traction. Wide-angle central tread slots pack snow while strategically placed 3D sipes provide additional biting edges to increase traction in wintry conditions.The HTR A/S P02 radial's internal structure features two rigid steel belts reinforced by full-width Jointless Nylon Band (JNB) technology featuring spirally wound reinforcement to promote long-term, high-speed integrity while it reduces tire weight and promotes more uniform ride quality. A high-tension polyester casing with high ply turn-ups anchored by an engineered bead package provide uniform wheel fit for responsive handling.
