How to Distinguish Between Forged and Cast Wheels?
1 Answers
Forged wheels and cast wheels can be distinguished as follows: 1. Style Type: Forged wheels are typically two-piece or three-piece, assembled using rivets or welding (argon welding), with noticeable color differences between the rim and spokes. Cast wheels are one-piece with no color variation. 2. Backside Details: Forged wheels are consistent in appearance, with both front and back sides being smooth and shiny with good metallic luster. Cast wheels may appear shiny on the front but darker on the back, with visible mold marks or burrs (though counterfeiters may polish the surface). Poorly made cast wheels may have pinholes or small pores on the back (though these may be hidden by paint or processing). Forged wheels usually have a flat back, while cast wheels have mold imprints. 3. Engraved Information: Wheel information (PCD, center bore, ET, etc.) on forged wheels is usually located on the inner rim wall (most common) or mounting surface. On cast wheels, it is typically found on the back of the spokes (most common), the back of the rim, or the mounting surface. Wheel information is rarely found on the inner rim wall of cast wheels. 4. Wheel Weight: Forged wheels are made through high-pressure forging, making them lighter than cast wheels of the same size and style. 5. Sound When Tapped: Using the tapping method, a small metal rod is used to tap the wheel. Forged wheels produce a clear, crisp sound, while cast wheels produce a dull, muffled sound.
