Changing a tyre using a swing-arm tyre changer requires precision and care to avoid damaging the wheel or tyre. Below is a step-by-step guide to help you perform the task safely and efficiently:
Step-by-Step Guide to Using a Swing-Arm Tyre Changer
Tools Needed:
Swing-arm tyre changer
Bead breaker
Lubricant (soapy water or tyre lubricant)
Tyre irons (if needed)
The Process of using swing-arm tyre changer video Valve core remover
Air compressor
1. Preparation
Deflate the tyre: Remove the valve core using a valve core remover to fully deflate the tyre.
Secure the wheel: Mount the wheel onto the tyre changer’s rotating table, ensuring it’s clamped tightly to prevent movement.
Adjust the swing arm: Position the swing arm and mounting/demounting head to align with the wheel’s diameter.
2. Breaking the Bead
Use the bead breaker on the tyre changer to separate the tyre bead from the wheel rim.
Position the bead breaker tool against the tyre sidewall near the rim.
Apply gradual pressure until the bead releases on both sides of the tyre.
3. Removing the Old Tyre
Lubricate the bead: Apply lubricant to the tyre bead and rim edge for easier removal.
Position the mounting head: Swing the arm into place and hook the mounting/demounting head under the tyre bead.
Rotate the table: Slowly rotate the wheel while the mounting head lifts the tyre bead over the rim edge.
Repeat for the lower bead by flipping the wheel (if required).
4. Mounting the New Tyre
Clean the rim: Remove debris or old lubricant from the rim.
Lubricate the new tyre: Apply lubricant to the new tyre’s bead and rim edge.
Align the tyre: Place the new tyre onto the rim at an angle, ensuring the bead sits correctly.
Use the swing arm: Position the mounting head to guide the tyre bead onto the rim as you rotate the wheel.
Start with the lower bead, then repeat for the upper bead.
Avoid pinching: Work slowly to prevent damaging the bead or tube (if applicable).
5. Inflating the Tyre
Reinstall the valve core: Use the valve core remover to tighten it back.
Inflate gradually: Use an air compressor to inflate the tyre in short bursts. Listen for the bead to "pop" into place against the rim.
Check pressure: Inflate to the manufacturer’s recommended PSI.
6. Final Checks
Inspect the bead seating: Ensure the tyre is evenly seated on the rim.
Balance the wheel: Use a wheel balancer to avoid vibrations while driving.
Safety Tips
Wear safety glasses and gloves to protect against debris.
Never stand directly over the tyre while inflating—use a safety cage if available.
Avoid excessive force to prevent rim scratches or tyre damage.
Pro Tip
For stubborn tyres, slightly warm the tyre bead with a heat gun (avoid overheating) to make it more pliable.
