This recommended practice applies to the laboratory measurement of the rolling resistance of pneumatic tires designed primarily for use on trucks and buses in normal highway service, as defined by the Tire and Rim Association, Inc. (TRA); it does not include light truck tires (designated LT). The procedure applies only to straight, free-rolling tires under steady-state operation and includes the following three basic methods:
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.
The Tire Committee is organized under the SAE Truck-Bus Council Total Vehicle Steering Committee and has the responsibility to initiate, develop, review and approve the SAE Technical Reports (Standards, Recommended Practices, and Information Reports) related to tires used on medium- and heavy-duty trucks and buses with GVWRs greater than 10,000 lbs. Such vehicles include vans, utility vehicles, trucks, truck tractor combinations, trailers and buses. This scope of work is done on behalf of the Total Vehicle Steering Committee, SAE Truck-Bus Council, the Technical Standards Board, and to serve the best interests of the public.The Tire Committee provides the support, review, and approval of the work of the following tire sub-committees and task forces: Truck Tire Characterization and Military Industry Tire
