Goodyear's Eagle ZR Gatorback is a specialty, Original Equipment (found pre-fitted on cars) tire with a high speed rating and designed specifically for racing or performance sports cars. It has a uni-directional tread that keeps a firm grip on the road. The rubber is treated to last a long time, as well. It is not rated for use in snowy conditions and does not provide as high a ride comfort or quietness rating as many of the other Eagle models. Handling and wet- and dry-road traction are this tire's main features.
