Nomenclature - Wheels for Passenger Cars, Light Trucks, and Multipurpose Vehicles
This SAE Recommended Practice establishes uniform engineering nomenclature for the most common wheel constructions, and their components used on passenger cars, light trucks, and multipurpose vehicles. These wheel constructions are welded “Disc Wheels”, “Cast Wheels” and “Forged Wheels”. This nomenclature and the accompanying drawings are intended to define fundamental wheel terms rather than to provide a comprehensive tabulation of all wheel design types.
Rationale: The major revision to this document was to include the geometry and associated nomenclature that is unique to forged and cast wheels. These wheels share many common features with disc wheels, but they also have many unique features that were not shown in previous revisions of this document.
