LABORATORY AND FULL-SCALE PARAMETRIC STUDIES OF THE ROLLING RESISTANCE OF RADIAL- AND BIAS-PLY HEAVY SERVICE TRUCK TIRES

A test program was performed at the Calspan Tire Research Facility (TIRF) to characterize the rolling resistance properties of current heavy-service truck tires. The tire sample included radial-ply and bias-ply constructions, in various load-range ratings and tread patterns, in the following popular sizes: 9.00-20, 10.00-20, 11.00-22.5 and 11.00-24.5. Test procedures, test matrix designs and corresponding response equations were developed to evaluate tire rolling resistance as a function of load and inflation pressure. A rolling resistance data base was formulated from tests on 30 different tires. Limited tests were performed on a 67.23-inch diameter drum to define the effects of small misalignments in the normal force vector and tire slip/camber angle on rolling resistance measurements. Limited-scope full-scale tests were made, using tires previously tested in the laboratory to attempt correlation between laboratory and field-test rolling resistance data based on the use of the draw-bar pull and vehicle coastdown techniques. The report describes the test program details and includes an analysis and a summary of the results.
