To which mechanical component are the vehicle's wheels directly attached using bolts or nuts?

Question

DentroTest · Accepted Answer

The correct answer is to the hub.  The hub is the central metal part that acts as the connection point between the wheel (rim and tire) and the vehicle's axle (suspension and steering system).    The Hub: This is where the wheel bolts or lug nuts are fastened. It rotates with the wheel and often supports the brake disc or drum.   The Engine: Generates mechanical power but is not in direct contact with the wheels.   The Gearbox: Manages power delivery from the engine to the drive shafts, but does not physically hold the wheels.
