Tire Rack, a direct-response sales company, has compared tire company products, including testing regular tires to low rolling resistance tires, to find the best low rolling resistance tires. Tire Rack compared low rolling resistance tires using the Toyota Prius. The company used all-season radial tires as a control for the tests.
The Michelin Energy Saver A/S tires delivered 53.8 mpg when tested on the Prius. This mileage is a 4.74 percent improvement over the control tires, according to Tire Rack.
The Bridgestone Ecopia EP100 delivered 53.5 mpg in tests. This is a 4.12 percent improvement over the all-season radial tires.
Two tires that fared worse than the all-season radial tires were the Michelin HydroEdge with Green X and Goodyear Assurance ComforTred. Michelin produced results that were 0.59 percent below the radial standard, while Goodyear performed at 2.64 percent less, according to Tire Rack.
