AN INVESTIGATION OF THE FUEL ECONOMY EFFECTS OF TIRE RELATED PARAMETERS

A program was conducted on a test track to determine the fuel consumption effects of radial vs. bias-ply tires, two radial tires from different manufacturers, and increased tire pressure. The program was designed to eliminate ambient effects by running two identical test vehicles simultaneously and alternating the parameter of interest between the two vehicles. Five different tire types were used (including the original equipment manufacturer tires from the vehicles). This study demonstrated that radial tires were six percent more fuel efficient than bias-ply tires; the radial tires from one manufacturer were four percent more fuel efficient than radial tires from a different manufacturer; and radial tires inflated to 28 psig were three percent more fuel efficient than radial tires inflated to 20 psig. This program also determined that laboratory measurements of rolling resistance are good predictors of track fuel consumption.
