How to distinguish between forged and cast wheels?

[LilahFitz]

Here are the specific differences between forged and cast wheels: 1. Wheel weight: Forged wheels are made through high-strength forging, so under the same size and style, forged wheels are lighter than cast wheels. 2. Style type: Forged wheels are usually assembled in two-piece or three-piece forms using rivets or welding (argon welding), with noticeable color differences between the rim and spokes; cast wheels are formed in one piece with no color difference. 3. Sound when tapped: When tapped with a small metal rod, forged wheels produce a clear and pleasant echo, while cast wheels produce a dull and low echo.
