The Champion Fuel Fighter (T-Speed Rated) is Firestone's Standard Touring All-Season tire developed for the drivers of coupes, sedans, family minivans and crossover vehicles looking for year-round capability and long treadwear combined with fuel efficiency and a comfortable ride.The Champion Fuel Fighter molds a silica-enhanced, Long-Link Carbon all-season tread compound into a symmetric design focused on even wear and easy rotation to provide miles of quiet service. Four circumferential grooves help guide water through the tire's footprint for improved wet grip while full-depth tread features provide the biting edges to enhance traction in light snow.Firestone's Fuel Fighter Technology is employed in the Champion Fuel Fighter to optimize the components and construction of the tire in an effort to improve fuel economy. Fuel Fighter Sidewall Technology uses an optimized compound design for added efficiency and the Fuel Fighter Steel Cord is a proprietary steel cord configuration that provides strength while adding less weight, further increasing the expected fuel savings.The tire's internal structure includes a one- or two- ply (depending on size) polyester body casing beneath two wide steel belts with a spirally-wrapped nylon reinforcement to deliver durability, ride quality and stability. The reinforcement utilizes Firestone's Fuel Fighter Nylon Application, an optimized application process focused on improving fuel economy. Related Information: Environmentally Conscious Manufacturing
