How to distinguish forged wheels from cast wheels?
2 Answers
Here are the methods to distinguish forged wheels from cast wheels: 1. Wheel markings: Forged wheels usually have the word FORGED printed on them, but it cannot be ruled out that some cast wheels may also have the same markings to pass off as forged. The color difference between the rim and spokes of forged wheels is obvious and can be easily noticed; cast wheels are formed in one piece with no color difference. 2. Details on the back of the wheel: Forged wheels are consistent inside and out, with both the front and back being smooth and shiny with good metallic luster, while cast wheels may have a shiny front but a darker back, with obvious mold marks or burrs (although it cannot be ruled out that counterfeiters may now polish the surface).
As a long-time car enthusiast, I believe distinguishing forged wheels from cast wheels requires some tricks. Forged ones are usually lighter and more rigid, with a smooth feel and a crisp, clear sound when tapped, thanks to the high-pressure forming process that creates a dense internal structure without bubbles. Cast wheels tend to be heavier, with surfaces that might feel rough or have uneven textures. They are cheaper but less strong, and more prone to deformation on rough roads. When I upgrade my wheels, I always go for forged ones—though much more expensive, the weight reduction and improved handling are totally worth it, which is why they're common in modified cars. To check, look for the manufacturing label on the inner side of the wheel—forged wheels are marked 'Forged,' while cast ones have a 'Cast' label, making it easy to identify at a glance. Don’t just trust the seller’s pitch; comparing the weight yourself is a surefire way to tell.
