This is one of the four ABS wheels supporting and driving the vehicle. The wheels are designed to provide the strength and stiffness required to jump transversely across ramps while having a low moment of inertia (which gives the vehicle faster acceleration.) The planar profiles were cut using a waterjet machining center, and the axial profile was turned on a CNC lathe. A hexagonal central hole keys the shaft to the wheel. Five small holes near the center of the wheel were used for fixturing the wheel to the CNC lathe.

If you look closely, you can see the seam where two quarter-inch thick sheets of ABS were bonded to form a half-inch-thick wheel. Around 30 hours of work went into the design and manufacture of the wheels.
