Book Description

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. 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. 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. During the 5 year review we found that dimensions for the wheel test adapter (wheel backup diameter) were missing from the document. SAE J694 was added to the document list. A note was also added to the procedure sections to go to SAE J694 for test adapter dimensions (wheel backup diameter). Appendix B was updated to include current production tires and their slr (static loaded radii).
