A man dressed inn a black shirt and camouflage print shorts is demonstrating how to fix the rubber tires on a car wheel rim.  He shows all the tools that are required to do the process.  He takes the rubber tire and sprays it with a liquid.  Then he fits the inner rim of the wheel into the tire.  He uses a mallet to secure it in tightly.  He then uses a tool to tighten the various screws that run across the entire diameter of the inner circle of the tire.  Then he uses a torque wrench to tighten the screws further.  He fills in air and checks the tire pressure.
