* Rim width: This is the distance between the mounting flanges on the wheel where the tire bead sits. This is typically measured in inches (e.g., 7 inches, 8 inches) and varies greatly depending on the car and wheel design.
* Rim depth/height: This is the distance from the mounting surface to the outer edge of the rim. Again, this varies widely based on wheel style. Some wheels are shallow, while others are very deep, affecting the overall "thickness" appearance.
* Overall thickness of the wheel and tire assembly: This would be the total thickness from the inside of the wheel to the outer edge of the tire. This would be substantially thicker than just the wheel rim alone and highly variable depending on the tire size.
Therefore, you need to specify what you mean by "thickness" to get a relevant answer. You'd need to look at the specific wheel's specifications.
