Scope:

This SAE Recommended Practice provides minimum performance requirements and uniform laboratory procedures for fatigue testing of wheels and demountable rims intended for normal highway use on trucks, buses, truck-trailers, and multipurpose vehicles. Users may establish design criteria exceeding the minimum performance requirement for added confidence in a design. The cycle requirements noted in Tables 1 and 2 are based on Weibull statistics using 2 parameter, median ranks, 50% confidence level and 90% reliability, and beta equal to 2, typically noted as B10C50. For other wheels intended for normal highway use and temporary use on passenger cars, light trucks, and multipurpose vehicles, see SAE J328. For wheels used on trailers drawn by passenger cars, light trucks, or multipurpose vehicles, see SAE J1204. For bolt together military wheels, see SAE J1992. This document does not cover other special application wheels and rims.

Rationale:

SAE J267 practitioners have typically performed multiple cornering and radial fatigue tests when assessing a wheel design’s conformance with this recommended practice. Running multiple tests enhances the confidence and reliability of the results. In this revision, this common practice has been formalized by introducing a set of sample sizes and corresponding cycle requirements based on Weibull statistics.

Previous publications of SAE J267 contained terminology to “provide minimum performance requirements”. This terminology was not consistently interpreted by practitioners. To clarify the meaning, a definition of the term “minimum performance requirement” has been added.

An additional cause for termination was added for aluminum wheels.
