How to Tell Cast Wheels from Forged Wheels

Cast and forged wheels — popular options for tuning and improving a car, but they differ in technology, characteristics, and price. Correct identification helps avoid overpaying or buying a low-quality product. In this article, we explain how to distinguish cast wheels from forged ones by their appearance and technical features.

Main differences in manufacturing

• Cast wheels: Made by pouring molten aluminum into a mold.
• Forged wheels: Produced by pressing an aluminum billet under high pressure. The result is a dense metal structure with high impact resistance.

How to identify the wheel type yourself

You can identify the wheel type by the following characteristics:

1. Weight. Forged wheels are noticeably lighter than cast ones — the difference can reach up to 20%.
2. Sound when struck. If you lightly tap the wheel with a metal object, a cast one will produce a dull sound, while a forged one will ring clearly.
3. Appearance. Forged models usually have a smoother surface without pores or microcracks.
4. Marking. The inner side of the wheel often indicates the type: «FORGED» — forged, «CAST» — cast.
5. Price. Forged wheels are more expensive but last longer and better withstand impacts.
6. Inner side of the wheel. Forged wheels show traces of mechanical processing.

Which wheels suit whom?

If you value comfort, aesthetics, and an affordable price — cast wheels are suitable. For dynamic driving, rough roads, and durability, forged wheels are the better choice.
