SAE J2530_200805

This SAE Recommended Practice provides performance and sampling 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 wheel performance can change if the wheel is chrome plated. Generally the fatigue performance will be equal or lower than the unplated version and the impact resistance can change with the plating process. Therefore, it is necessary to revise the document to clarify how to select plated wheels and verify that cracks in the plating only are not failures. The questions on how the wheel manufacturer determines if the crack is through a section of the wheel is left to several analytical methods but does not need to be specified in this document. The Wheel Committee reviewed the plated options used in the aftermarket and concluded that we should add a general statement on finishes that require the wheel manufacturer to test the worst case. The focus on chrome works for OEM wheels but the many finishes used currently and potentially in the future make it important that all be evaluated.
