If this already exists, I apologize. I’ve always like the challenge of searching for solutions rather than simply asking, but these search results are really strange.
On one E38 board, I’m seeing what I think **may** be some inaccurate information about which OEM BMW wheels are forged and which are cast.
V12 vehicles typically feature forged wheels. This is applicable to the E38 and E31 V12s and dates back to the E32 750il. The 8 cylinders don’t. The five double-spoke M3 LTW wheels were also forged. The casting and forging of the M-system II wheels (throwing stars) can be seen by looking at the design surrounding the hub when the covers are removed. If you can take a high-resolution photo of the wheel markings, you can easily distinguish between a cast and forged wheel. The marks on a cast wheel will be raised (cast in, of course), whereas the markings on a forged wheel are etched. I am aware that the E39 M5 wheel is cast and rather heavy. I’m not sure if BMW uses any forged wheels on their more recent vehicles; perhaps the cost is just prohibitive when you consider 19- and 20-inch wheels.

I’ll simply say they’re all heavy to wrap it up. The E90s’ 18″ sport wheels weigh a friggin ton.
Volk TE37s in bronze, 18″ weigh 17lbs, if I had the money. Forged, powerful, and absurdly light all at once. Stupid dollars, too.
Except for the M3 wheels mentioned before, I would assume that nearly all of the wheels are cast at this time. Forged wheels only bend rather than cracking. After hitting a few potholes, every wheel I’ve had to replace has developed a crack on the inside lip, or in the case of the original E60 545 wheels (18″ package), real spoke cracks.
There are OEM BMW wheels that are forged that are not M. I have forged E46 wheels from very early 323i vehicles. right there in the ETK. The 13.2 lb. weight seems to support that as well.

Are the wheels on BMW forged or cast aluminum? The wheels on my 2003 BMW 330i have 20 spokes; I’m not sure of their code numbers, but I adore how they appear. I was simply curious if anyone knew because I saw a TV program that demonstrated how each type was manufactured and stated that forged are significantly stronger and lighter. Thanks.
majority are cast. The only E46 3er wheels that are forged, in my opinion (I could be dead wrong), are the optional 19″ M3 wheels.
Due to the higher cost of forging, only a select few manufacturers offer forged wheels as standard equipment. By contrasting the costs of similar aftermarket wheels, you can notice the differences.
forged wheels for the BMW M3?
Kristian: Forged aluminum wheels are used only as summer wheels on the new BMW M3 and M4. The two M Performance Stylings, 963M and 1000M, as well as the standard wheel Styling 824, are even entirely machined. A cast wheel is the winter wheel 829M.
BMW BBS wheels are they forged?
Since 1983, BBS has provided forged aluminum wheels for the aftermarket. We are able to produce the toughest and most durable wheels available thanks to our unique multi-stage Die-Forging procedure. These aircraft quality alloys are forged with up to 18 million pounds of pressure starting with a billet of 6000 series or even a unique 7000 series Dura aluminum. The greatest forged wheels in the business are produced by optimizing and controlling every stage of the production process internally. For the most unusual applications, we can also create forged wheels from magnesium alloy at OEM quality.
Porsche wheels are they forged?
The totally tailored forged wheels for Porsche are constructed from one solid piece of metal. The wheels are forged in one piece under high pressure and heat. They are stronger than cast wheels as a result. During the heating cycle, the material’s grain is smoothed out. Compared to cast wheels, it uses less material while yet producing structural integrity. Forged wheels are stronger and more durable even though the equipment used to make them is more expensive. Both handling and performance are rated as excellent. According to Tyres.Net, the forged wheel has a greater wear resistance rating, is mechanically stronger, and is less likely to develop cavities, porous regions, or shrinking.
M wheels forged, or not?
As a point of clarification, not all M-wheels are forged; some M-wheels are cast. The best way to tell is to examine the wheel’s back side. The molten alloy is poured into a mold to create a “cast” wheel. As a result, you will see “raised lettering” used to identify the wheel’s specifications. This enables the specs and other identifiers to be incorporated into the mold. You may also visibly tell that a wheel was made in a mold by various indentations on the backside of spokes, for example.
Note the raised lettering and indentations that were designed into the mold in the photographs below of the rear side of the 373 wheel.
A solid alloy piece is used to forge the wheels. The spokes and usually solid back of the wheel are the visual effects of this manufacturing procedure. If there is an indentation, it would have to be cut or carved out of the solid block of alloy; you won’t see any dips or other indentations. Additionally, due to the production process, any identifying information or writing must be “engraved” or cut into the backside of the spokes, therefore the forged alloy portion of the wheel cannot have raised text.
Here is an illustration of the back of a cast 373 alloy wheel with raised writing and indentations on the back of the spokes:
What material are BMW wheels composed of?
When a BMW leaves the dealership, alloy wheels are the most prevalent type of wheel. Similar to the paint job on your car, they are comprised of lightweight aluminum and finished with bright silver or a flat metallic tint before being clear coated. To match the size of your tires, alloy wheels are available in a variety of sizes. There are numerous spoked, vintage, and other variations. Your alloy wheels will require care and upkeep, much like the paint on your BMW and its parts.
OEM wheels are they forged or cast?
Casting pressure is minimal for OEM wheels. Many aftermarket wheels are forged or semi-forged, making them more durable than any cast OEM wheel. To put it simply, certain aftermarkets are stronger than others.
Who makes the BMW wheels?
Bentley Wheels Beyern Wheels is the main supplier of alloy wheels for BMW vehicles. Exclusively for BMW, they have a series of unique wheels. Even the 3, 5, 6, 7 series and the X3, X5, Z3 and Z4 have unique designs.
If so, do they crack?
And now for the forged wheels. The strongest and lightest wheels on the market, these are at the top of the wheel performance pyramid.
Due to the specialized production process, forged wheels are undoubtedly more expensive. However, a forged wheel resists cracking if the wheels are subjected to a sudden impact when quality, safety, and performance are on the line. However, if necessary, the wheel can be restored when damaged.
These factors drive competitive racing professionals and automobile fans who spend a lot of time on the track to seek for the best in terms of performance, quality, and safety. Forged wheels are always the finest option for any scenario where the wheels are under pressure.
Another factor contributing to the popularity of forged wheels is their complete customization to the needs of the buyer. As a result, the lead time to complete a custom order can differ depending on the manufacturer. For those that require a high-quality product, working with a manufacturer who can finish the order within a reasonable time limit is crucial.
Are forged wheels flexible?
In the event of a significant hit, the forged aluminum wheel will bend as opposed to cracking. It’s crucial to understand the mechanics of bending since it will make it more likely that you can stop your car or deviate from the path you’re on safely.
Are BBS wheels forged or cast?
BBS creates our base light alloy wheels using the low-pressure aluminum casting method. Our cast wheels attain the same stiffness to weight ratio as the rest of our products.
Cast wheels or forged wheels—which is better?
There are numerous ways to make wheels. Wheels made using the “cast” and “forged” production processes are two of the most common. Each variety has its own unique manufacturing process and set of benefits and drawbacks.
In the casting process, molten aluminum is poured or vacuum-inserted into a mold that has been shaped in various ways to resemble a wheel. In order to more quickly insert the aluminum alloys into the mold and produce a wheel with a higher density than a gravity cast wheel, positive pressure is applied. It is permitted to cool. The wheel is then subjected to minor alterations like drilling and trimming. This manufacturing method is chosen above others because it is quick and affordable. Additionally, it is simpler than other processes.
Cast wheels are strong and light while also providing a fair value for a tire. Because they are simpler to produce, the cost savings are frequently passed on to the customer.
Allowing the molten aluminum to solidify can produce irregularities that can lead to the wheel’s fracture and oxidation. Through this manufacturing process, the structural integrity of the wheel can be compromised. It may be necessary to make the wheels heavier to account for this potential issue.
Forged wheels start out as a solid piece of metal that is then compressed by heat and extreme pressure. Depending on the wheel design, this material is forged into varied diameters.
A forged wheel starts out as a solid piece of metal called a “billet,” in contrast to casting. Afterwards, heat and high pressure are applied to the billet, compressing the material to create a raw forging. To enable the development of various wheel designs, these raw forgings are “forged” into distinct profiles.
Due to the forging process, forged wheels are less porous than cast wheels. These wheels are stronger, more resilient, and less prone to corrosion and oxidation thanks to the forging process. Furthermore, the wheel’s structural integrity remains unaffected. Wheels made of forged metal typically perform better overall and use less gasoline.
A more accurate and time-consuming method is forging. Due to the higher cost of the process, buyers pay extra for the wheels. Some customers might not be prepared to pay the additional price expected of forged wheels because cast wheels can also be high-quality wheels. Falsified ones, however, are of incomparable worth to buyers.
Getting an expert’s perspective is crucial when choosing between cast wheels and forged wheels. The size and kind of the vehicle you drive, your driving habits, and your budget can all influence the best wheel type.

A rotating forged wheel is what?
TSW produces ROTARY FORGEDTM WHEELS employing rotary forging, a very sophisticated production method. Wheels are spun at a fast speed while the rim is forged under tremendous pressure. The molecular structure of the alloy is changed, increasing the alloy’s strength. The advantage is that the wheel is substantially lighter than a typical cast wheel. The outside rim of the wheel is where the weight is saved most significantly, which significantly reduces rotational mass and improves vehicle performance.
