This SAE Recommended Practice provides uniform laboratory procedures for biaxial fatigue testing of wheels intended for normal highway use and temporary use on passenger car vehicles and light trucks and minimum cycle requirement for ferrous wheels for ballasted passenger car applications. The appendices provide scalable load files that are applicable to ballasted passenger cars and ballasted light trucks. A load file for unballasted passenger cars will be added to this document.
SAE Paper 2014-01-0073 Minimum Cycle Requirement for SAE J2562 defines the empirical data with industry accepted statistics a minimum requirement can be projected, below which a wheel design will likely have samples unserviceable in its intended service. The projections of serviceability result in a recommendation of a minimum requirement for SAE J2562 ballasted passenger car service.
An alternative to a vehicle hub is a test adapter with the shape of a wheel hub that represents the functional stiffness of a production wheel attachment that is referred to as a Silhouette.
