A tire changing machine can help you mount and dismount car tires from wheels. There are several different types of tire changing machines available, including one designed to change the tires of motorcycle wheels and one that is designed to change heavy duty tires such as those found on big rig 16-wheel cargo trucks and off-road farming equipment. Most tire changing machines also include auxiliary systems that allow you to inflate new tires, preparing them for use on the road.
Remove the core of the wheel's valve with a valve core remover.
Wedge the bead breaking blade between the inside of the tire and the rim of the wheel, and then set the blade into position.
Press the bead breaker pedal of the tire machine with your foot to break the bead, i.e., the edge of the tire that sits on the wheel.
Place the wheel on top of the clamps, while ensuring that the clamps are set in the outer configuration. Press the wheel clamp jaw pedal with your foot.
Move the mount/demount head onto the rim of the wheel, and then pull the vertical bar lock lever.
Insert a tire iron between the inside of the tire and the dismount head, and then use it to pull the inside of the tire over the dismount head.
Press the rotation pedal with your foot, and then lift the tire to dismount the backside.
Pull the backside of the tire over the dismount head with the tire iron. Press the rotation pedal with your foot.
Rub tire lube inside the new tire, and then place the tire on top of the wheel.
Lower the mounting head between the backside of the tire and the rim of the wheel. Press the rotation pedal with your foot.
Attach the inflation hose to the valve stem and press the inflation pedal all the way down with your foot to initiate the bead blaster. Once the bead is fully seated, partially press the inflation pedal to inflate the tire.
Do not over inflate the tire.
