The Eagle F1 GS EMT (Extended Mobility Technology) is Goodyear's Ultra High Performance Summer self-supporting run-flat tire developed for C5 Corvette coupes, convertibles and hardtops. Featuring Goodyear's Extended Mobility Technology, these tires provide temporary mobility even after a puncture results in complete loss of air pressure. The Eagle F1 GS EMT is designed to blend wet and dry traction with treadwear, however like all summer tires, it is not intended to be driven in near-freezing temperatures, through snow or on ice.
