Scope
This SAE Recommended Practice describes a test method for determining the vertical force and deflection properties of a non-rolling tire and the associated contact patch length and width. The method applies 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 use in 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 pavements. Within the context of this Recommended Practice, forces applied to the pavement are not considered.
Rationale
J2704 has been reaffirmed to comply with the SAE 5-Year Review policy.

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.
