The Eagle F1 Asymmetric is Goodyear's Max Performance Summer tire developed for modern high performance vehicles that are more advanced, intelligent and luxurious than ever before. However since these vehicles are also more powerful, faster and heavier, they require tires that can provide control without conceding comfort. The asymmetric in the Eagle F1 Asymmetric name describes both the tire's tread design and internal structure, both of which are designed to enhance performance in dry and wet conditions. Like all summer tires, the Eagle F1 Asymmetric is not intended to be driven in near-freezing temperatures, through snow or on ice.Goodyear's warranty states: "Ultra high-performance summer tires are not recommended for winter use, and tread or shoulder cracking on those tires resulting from winter use will not be covered under our warranty."The tread uses Goodyear's Racing Compound Technology to combine carbon black for dry traction, silica for wet traction and a new generation of polymers to optimize tread stiffness. This compound is molded into an asymmetric tread design with wide, solid outboard shoulder blocks to increase cornering traction while a continuous center rib improves high speed stability and an open inboard tread pattern disperses water. Wide circumferential grooves also allow water to flow from between the tire footprint and road.The internal structure of the Eagle F1 Asymmetric includes twin steel belts reinforced with three layers of spirally wrapped polyamide cord to enhance tread stability and high-speed capability. Goodyear Active Cornergrip Technology includes the addition of aramid reinforcement in the inboard sidewalls to provide a more even contact with the road for more even distribution of pressure across the whole contact patch when cornering.
