Using a tire changing machine involves several steps to safely and efficiently remove an old tire from a wheel and install a new one. Here’s a general guide on how to use a typical tire changing machine:
-
Prepare the Machine and Tire:
- Ensure the machine is properly set up and all components are secure.
- Set the tire and wheel assembly onto the machine. Make sure the tire’s valve stem is aligned with the corresponding part on the machine to avoid damage.
-
Break the Bead:
- The bead is the edge of the tire that sits firmly against the wheel. Most tire changers have a bead-breaking component.
- Position the bead breaker against the tire’s bead and activate it. This will separate the bead from the rim. Rotate the tire and repeat the process to ensure the bead is fully broken around the entire circumference.
-
Mount the Tire onto the Machine:
- Place the wheel onto the clamping device of the machine. Secure the wheel according to the machine’s instructions, ensuring it is tight and will not slip.
-
Remove the Tire:
- Insert the tire iron (or mount/demount bar) between the tire and the rim to pry the tire over the rim. This might require some force.
- Rotate the turntable of the machine to work the tire iron around, lifting the tire off the rim.
-
Mount the New Tire:
- Lubricate the edges (beads) of the new tire to make installation easier.
- Place the edge of the tire over the rim and use the tire iron to help guide the tire into place. Start with one side, ensuring it’s fully seated, then do the other side.
- Once the tire is on the rim, inflate the tire to ensure the beads are properly seated against the rim. You should hear a popping sound as the tire moves into place.
-
Inflate the Tire:
- Attach the air hose to the tire’s valve stem and inflate the tire to the recommended pressure.
-
Inspect and Balance:
- Once the tire is mounted and inflated, inspect it to ensure it is seated correctly and there are no damages.
- Balance the tire using a wheel balancer to ensure smooth driving.
-
Reinstall the Wheel:
- Once the tire is balanced, you can reinstall the wheel onto the vehicle.
Always refer to the specific instructions provided with your tire changing machine, as different models and brands may have unique features or steps. Safety is crucial, so wear appropriate protective gear and follow all safety guidelines.
