Scope
This SAE Recommended Practice describes test methods for measuring and identifying the natural frequencies for the lower order modes of an inflated radial tire with a fixed spindle while expending modest effort and employing a minimum of test equipment. The methods apply to any size of radial tire so long as the test equipment is properly scaled to conduct the measurements for the intended test tire. Two types of boundary conditions are considered for the tire: unloaded and loaded against a flat surface. The test involves the performance and measurement of an input vibratory force (excitation) to the tire and the corresponding vibratory output (response). 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 1—The focus of this standard is identification and reporting of the lower order natural frequencies of the tire using a simple test procedure. While higher order natural frequencies may be excited during these tests, the reliable identification of the associated mode shapes is not addressed in this document.
-
NOTE 2—Herein, road load models are models for predicting forces applied to the vehicle spindles during operation over irregular surfaces, paved or otherwise. Within the context of this document, forces applied to the road or terrain surface are not considered.
Rationale
J2710 has been reaffirmed to comply with the SAE five-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.
