GT Radial Champiro HPY. FEATURES AND BENEFITS: Summer weather traction; Enhanced controllability; Reduced road noise levels; High speed performance; . OVERVIEW: The GT Radial Champiro HPY is a high performance, summer tire manufactured for passenger vehicles and SUVs.The tire promotes excellent summer weather traction. The silica-based tire compound and the asymmetric dual tread design increase the dry and wet weather road gripping ability. They firmly grip the road surface in these conditions, but the tire will not perform well in colder temperatures. The asymmetric tread's inner area and the four wide circumferential grooves actively resist hydroplaning by dispersing water and slush from below the tire's footprint. The increased road gripping ability and hydroplaning prevention ensure a safer summer weather performance.The tread design's constant road contact boosts the model's controllability. The wide solid center rib keeps the tire close to the road surface at all times, which improves the steering responsiveness and driving stability greatly. This makes the steering responsiveness to the driver's commands faster and more precise, while it stabilizes the tire's structure against the driving pressure affecting it during the drive. The outer tread design optimizes the model's road contact, which upgrades the cornering ability and power. The better road contact improves the number of biting edges that grip the road surface and ensure a safer drive and better controllability in summer weather.The tire's asymmetric tread design manages to reduce the road noise levels heard while the tires are in motion. The asymmetric tread design prevents road noise from generating by channeling the airwaves through the tire's footprint without letting them come into contact with the tread elements. This ensures lowered road noise levels heard in the vehicle's cabin and promotes a comfortable and quiet driving experience in all summer weather.The Champiro HPY provides first-rate high speed performance. The asymmetric tread design, the solid center rib and the silica compound all increase the summer weather traction and keep the tire's road contact constant. This allows the model to perform to its highest capability in dry and wet conditions, ensuring the tire's excellent high speed capability. Manufacturers recommend changing tires every 10 years. As long as tires are properly stored before they are sold, the year of their manufacture will not shorten their service life.
