Scope
This SAE Recommended Practice describes a trio of test methods which determine basic tire size (geometry), mass, and moments of inertia. The methods apply to any tire so long as the equipment is properly scaled to conduct the measurements for the intended test tire. The data are suitable for determining parameters for road load models and for comparative evaluations of the measured properties in research and development.
NOTE: Herein, road load models are models for predicting forces applied to the vehicle spindles during operation over irregular surfaces paved or unpaved. Within the context of this Recommended Practice, forces applied to the surface on which the tire is operating are not considered.
Rationale
This technical report is being Stabilized because it covers technology which is mature and not likely to change in the foreseeable future.

Issuing Committee
Vehicle Dynamics Standards Committee
The Vehicle Dynamics Standards Committee (VDSC) reports to the Vehicle Performance Steering Committee. The VDSC develops Information Reports, Recommended Practices and Standards related to the dynamics of passenger cars and light trucks, excluding trailers. The committee establishes tests and analyses that contribute to the understanding of the ride and handling performance of the total vehicle as a dynamic system.

* 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.
