Born on the track, the Eagle F1 Supercar 3R is Goodyear's Streetable Track & Competition tire originally developed for the Chevrolet Camaro ZL1 1LE and designed to deliver world-class handling, motorsports levels of traction and consistently fast laps. Like all summer tires, the Eagle F1 Supercar 3R is not intended to be serviced, stored, nor driven in near-freezing temperatures, through snow or on ice.Utilizing polymers and resins previously only used in racing slicks, the tread compound of the Eagle F1 Supercar 3R was selected from multiple iterations after extensive on-track evaluation. The asymmetric tread pattern and geometry were optimized through computer modeling before track testing determined the final design, which has a massive, low-void outboard shoulder to provide extreme levels of lateral grip. The rigid, notched center ribs offer responsive, precise steering and longitudinal grip, and the lateral notches and circumferential grooves aid wet traction.The internal construction of the Eagle F1 Supercar 3R is designed to be lightweight to enhance steering and handling precision. The two-ply, rayon casing utilizes a high turn up to improve handling response, resulting in a three-ply sidewall. The two wide, steel belts are reinforced by a single, polyamide reinforcement ply.Warning: Eagle F1 Supercar 3R radials meet DOT requirements, however, they are not recommended for driving in wet conditions where standing water is present and there is the risk of hydroplaning; drivers should drive cautiously at reduced speeds if they encounter these conditions. This is especially true of shaved or worn tires.Note: Tires exposed to temperatures of 20 degrees F (-7 degrees C) or lower must be permitted to gradually return to temperatures of at least 40 degrees F (5 degrees C) for at least 24 hours before they are flexed in any manner, such as by adjusting inflation pressures, mounting them on wheels, or using them to support, roll or drive a vehicle.Flexing of the specialized rubber compounds used in Streetable Track & Competition tires during cold-weather use can result in irreversible compound cracking. Compound cracking occurs as the result of improper use or storage, and Goodyear's warranty specifically excludes tires exhibiting this condition from coverage. Any tires exhibiting compound cracking must be replaced.
