Are OEM wheels made by casting or forging?

OEM wheels are made by casting. Here is some related information about wheels: Introduction: A wheel hub is the rotating part that connects the tire's inner contour to the wheel's core via pillars, i.e., the metal component mounted on the axle that supports the tire. It is also called a rim, wheel ring, or wheel disc. Wheels come in various types based on diameter, width, forming method, and material. Wheel types: Wheels are also called rims. Depending on the characteristics and requirements of different vehicle models, the surface treatment process of wheels may vary, generally categorized into painting and plating. For ordinary vehicle models, wheels are less considered in terms of appearance, with good heat dissipation being a basic requirement. The manufacturing process typically involves painting, i.e., spraying followed by baking, which is cost-effective, offers vibrant colors, and maintains durability over time. Even when the vehicle is scrapped, the wheel's color remains unchanged.
As a seasoned driver with over a decade of experience, I've changed my car's wheels several times, and the OEM ones are almost always cast. Cast wheels are made by melting aluminum alloy and pouring it into a mold to form, a process that's simple and cheap, allowing manufacturers to control costs during mass production. This means that when we regular car owners buy a new car, the wheels aren't too expensive and can withstand daily use, whether it's city driving or highway cruising. Of course, cast wheels are a bit heavy, which might slightly affect fuel consumption, but it's hardly noticeable during normal driving. I've hit a pothole that dented a wheel once, but it only deformed slightly without immediate failure, and replacing it cost just a few hundred bucks. Choosing OEM parts is all about peace of mind and cost-effectiveness, which is how most car brands design them. Remember, regularly check your wheels for cracks when driving—safety first, and don't cut corners by modifying wheels recklessly.
