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

Rolling loss tests were performed on 31 different passenger and 4 light truck tires under transient and equilibrium conditions. The tests were designed to determine the effects of load, speed, inflation pressure, tire temperature, slip angle, torque, tire construction, aspect ratio and wheel diameter. In addition, the influences of road curvature (flat roadway, drum) and trip length on rolling resistance were investigated. The results are presented in tables and graphs. They are expressed in terms of 12 power loss descriptors (for each tire), stating initial values, equilibrium values, and distances required to achieve equilibrium, for rolling resistance, contained air temperature, tread surface temperature, and inflation pressure.
