What is the German word for 'rim'?

The German word for 'rim' is indeed "Felge." This term specifically refers to the outer edge of a wheel, which is crucial in various contexts such as automotive or bicycle components. Rims are essential for holding the tire in place and supporting the load of the vehicle, making understanding the terminology important for clear communication in technical discussions about wheels and tires.

The other options provided refer to different items: "Schicht" means 'layer,' which is unrelated to the concept of a rim; "Stecker" translates to 'plug,' commonly associated with electrical components; and "Lastenträger" refers to 'cargo carrier' or 'load carrier,' which describes a system for transporting items, rather than a component of a wheel. Thus, "Felge" is the correct term related to the context of a rim.
