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.
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
* Redlines comparisons are available for those standards
listed in the Revision History that contain a radio button. A
redline comparison of the current version against a revision is
accomplished by selecting the radio button next to the standard and
then selecting 'compare'. At this time, Redline versions only exist
for some AMS standards. SAE will continue to add redline versioning
with ongoing updates to SAE MOBILUS.

Using the asterisk, ( * ) allows you to search for a partial word. For example, entering a keyword search of aero* will search for any word beginning with aero.
Using the question mark, ( ? ) allows you to search for a word with a single character wildcard. For example, searching for t?re would match both tire and tyre
Using Quotes
Words in double quotes " " are treated as a phrase. Conducting a search for "heat model" will return all results in which the exact phrase "heat model" is found, while "heat modeling" would NOT be included.
A term combined with a phrase will be joined with an OR operator.
Searching for Standards
When searching for a standard please use the entire Document Number assigned, which includes the abbreviation. A space can be used, or omitted between the abbreviation and number.
