Scope
This SAE Recommended Practice describes the determination of tire pull force properties for an uninclined tire (SAE J670e) on a laboratory flat surface tire force and moment machine. It is suitable for accurately determining pull forces and residual aligning moments for passenger and light-truck tires. These properties are important determinants of vehicle trim (See section 2.1.2). They describe steady-state, free-rolling pull effects ascribable to tires.
The test method described in this document is suitable for comparative evaluation of tires for research and development purposes. The method is also suitable for modeling when followed carefully.
Rationale
Committee recommends to stabilize the document. Auto and tire manufacturers are running their own force and moment methods so there seem to be no users of the document. However, if the Committee determines in the future that by revising the method more users could be attracted to use it, then the document can be brought out of stabilization for revision.

Issuing Committee
To plan and execute a cooperative tire test development program, to evaluate the fatigue endurance performance of light duty highway tires. Activities will include empirical comparisons of tire performance on the various, proposed tests, together with evaluating reasonable relationships to tire usage and durability performance on the highway.

* 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.
