This SAE Recommended Practice provides performance, sampling, and certifying requirements, test procedures, and marking requirements for aftermarket wheels intended for normal highway use on passenger cars, light trucks, and multipurpose passenger vehicles. For aftermarket wheels on trailers drawn by passenger cars, light trucks or multipurpose vehicles, see SAE J1204. These performance requirements apply only to wheels made of materials included in Table 1 and Table 2. New nomenclature and terms are added to clarify wheel constructions typically not used in OEM applications. The testing procedures and requirements are based on SAE standards listed in the references.
The marking stamp size was reduced by 0.2mm to match the DOT size. The marking includes rim size designation which adds the rim profile to the currently stated rim diameter and rim width. THE LARGEST OVERALL DIAMETER OF AN INSTALLED TIRE (CURRENTLY AN OPTIONAL MARKING) WAS DELETED. The wheel supplier defintions were added to include the added Importer of record, Remanufacturer, Vehicle manufacturer, and Wheel manufacturer, producer, or fabricator. Added minimum performance requirement to the definitions and added Kinstler SAE paper on the science and methodology of SAE Wheel fatigue test specifications. The test termination for the rotary fatigue test (section 6.5e) was clarified to provide wording to show repeated lug bolt failures are a reason for test termination and that the cause can be investigated and if not caused by the wheel, then the test can be invalidated.
