EQUILIBRIUM AND TRANSIENT ROLLING RESISTANCE OF TRUCK TIRES MEASURED ON CALSPAN'S TIRE RESEARCH FACILITY

A test program designed to characterize the rolling resistance characteristics of those tires to be used for the ongoing DOT/SAE Truck and Bus Fuel Economy Verification Program was conducted at the Calspan Tire Research Facility (TIRF). The tire sample included both radial-ply and bias-ply tires in four of the most popularly used sizes: 9.00-20/F, 10.00-20/G, 9.00R20/F, and 11522.5/G. Tests were conducted to measure rolling resistance sensitivity to variations in speed, load, inflation pressure and torque with the tire in both equilibrium and nonequilibrium states. Rolling resistance measurements (free-rolling) were made on both a flat roadway and a 67.23-inch diameter drum. A short description of the test program and a summary of the results are included.
