The Eagle F1 Supercar G: 2 (Generation 2) ROF (RunOnFlat) is Goodyear's Extreme Performance Summer, self-supporting run-flat tire initially developed as Original Equipment (O.E.) for 2011 Chevrolet Corvette ZO6 sports cars. The Eagle F1 Supercar G: 2 ROF is designed to be street-refined and track-capable by combining an aggressive appearance with awe-inspiring performance. However, like all Extreme Performance Summer tires, these tires are not intended to be serviced, stored nor driven in near- and below-freezing temperatures, through snow or on ice.
