This report described the results of tests on twelve passenger car tires performed on Calspan's Tire Research Facility (TIRF). The tests were used to measure energy loss under three different test conditions: (1) with the tire in a straight, free-rolling condition; (2) with the tires subjected to driving/braking torques required by conformance to the Federal Urban Driving Cycle (LA-4); and (3) with the tires subjected to driving/braking torques required by conformance to the Federal Highway Fuel Economy Test (HFET). The sample set of tires was representative of current original equipment, and ranged in size from a P155/80D13 to an HR78-15.
