A wheeled hand truck installs, removes, and transports rim-mounted tires and brake drums for vehicles. The truck comprises an elongated frame and extended fork section supported by a transverse axle having wheels at the ends bracketing the frame. The frame includes a handle section extending opposite the fork section that terminates in a grip. The fork section extends opposite the handle for straddling beneath a tire or drum on both sides of its center of gravity. The tire rests against the handle portion and fork, while the drum is mounted in a movable cylinder. The tire or drum is transported by balancing the weight of the tire on the wheels while pushing on the grip. The truck also has an extended lift step for providing leverage, a kickstand, an oil catch pan for brake drum drips, and grab pins for spoke-type hub and drum assemblies.
