Goodyear Eagle GS-C EMT tires are original equipment for C4 Corvette coupes and convertibles, with a slightly different diameter in the front and rear. They incorporate high performance features in the compound used in construction to grip pavement. The asymmetrical tread design includes wide outboard shoulders with tread blocks that promote both wet and dry traction. Radial belts inside the tire work to increase durability and prevent punctures, and work with spirally would aramid overlays to support high speed durability. Extended Mobility Technology uses reinforced sidewalls that can temporarily support the weight of the vehicle in case of loss of air pressure.
