The Measurement of Highway Truck and Bus Tire Rolling Resistance(STABILIZED Nov 2020)
J1380_202011
The force, torque, and energy methods of measurement are all in common use and should yield the same test results. Effects of steering, traction, and non steady-state tire operations are excluded from the recommended practice because they are still in the research stage. Methods of correcting laboratory data to road conditions are being developed.
Rationale:
This technical report is being stabilized because the technical committee has determined that the using community is moving towards newer technology and would like to alert users that this new technology exists which may want to be considered for new design. Refer to SAE J1269 and SAE J1270 for rolling resistance measurement.
