Scope:

This SAE Recommended Practice provides uniform procedures and minimum performance requirements for fatigue testing ferrous and aluminum wheels intended for normal highway service on travel, camping, and boat and light utility trailers drawn by passenger cars, light trucks, and multipurpose vehicles. For procedures and minimum performance requirements for wheels used on trucks, see SAE J267, and for wheels used on passenger cars, see SAE J328. For the application of passenger car and light truck wheels (inset less than 0.10 m) to this trailer service, use this procedure. For the application of heavier truck wheels (inset 0.10 m (or more)) use SAE J267. Mobile home service is outside the scope of this document.

There are two basic test procedures described, a cornering fatigue test and radial fatigue test. The cornering test is directed at the wheel disc; whereas the radial test also examines the rim and attachment portion of the wheel. Both test procedures are required to obtain a thorough examination of the wheel.

Rationale:

Definitions were revised to reflect those of SAE J2530.

Wheel markings were added same as in SAE J2530 to reflect marking standard in light truck pass car and aftermarket wheels.

Test termination revisited to be same as in SAE J2530 for consistency.

A method of calculating SLR recommended by JATMA and Tire & Rim Association.

Test sample selection and associated cycles necessary to maintain B90C50 confidence of results see Tables 1 and 2.

A reduced service factor and associated increased cycle requirement are added to Table 2. Reduced service factors allow for better time efficiency of fatigue tests where tire consumption or stud breakage is excessive.
