The Eagle F1 Supercar EMT is Goodyear's self-supporting, run-flat Max Performance Summer radial developed as Original Equipment for sports cars, (C-6 Corvette equipped with Chevrolet's Z51 Performance Package and C-6 Corvette Z06), and performance sedans (Cadillac CTS-V). Eagle F1 Supercar EMT tires emphasize dry road traction and handling, and feature Goodyear's self-supporting Extended Mobility Technology (EMT) to provide temporary mobility even after a complete loss of air pressure while eliminating the traditional spare tire and wheel to allow more storage and luggage space. Like all summer tires, they are not intended to be driven in snow.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."Eagle F1 Supercar EMT tires feature a high-grip Goodyear AAtrax tread compound (the AAtrax name emphasizing that the Eagle F1 Supercar EMT earns the highest "AA" Uniform Tire Quality Grade wet traction rating) molded into a slightly reduced tread depth (9/32" instead of traditional 10/32") asymmetric tread design that combines large outer shoulder and intermediate tread blocks to increase initial steering response and cornering stability with a solid center rib to maintain constant road contact and enhance straight-line tracking. Wide circumferential grooves and smaller interior tread and shoulder blocks help water escape from between the tire and the road to maintain wet traction and hydroplaning resistance. The tire's structure includes twin, high-tensile steel belts reinforced with spirally wound Aramid to distribute the vehicle's load across the tire's footprint providing high-speed durability and uniform ride qualities. Rayon body plies enhance high temperature and high-speed durability while exterior sidewall rim flange protectors help guard wheels against curb damage.
