Do I need electricity to use this tyre changer?

No electricity is required, but you do need an air compressor delivering 8-10 bar with 8-10.5 gallon capacity. The compressor is not included.

What tyre sizes can it handle?

12 to 21 inch rim diameter, covering most passenger cars, SUVs and light trucks, with a maximum wheel diameter of 39 inch (1000 mm).

Is it really portable?

Yes. It weighs 38 kg, needs no bolting down and folds into a car boot.

Installation & usage guide

Step-by-step instructions, taken from the official user manual.

How it works

Compressed air runs from your compressor outlet into the tyre changer’s air inlet.
That air drives the large cylinder and foot pedal assembly.
Pressing the pedal extends and retracts the cylinder rod.
On retraction the cylinder pulls the bead breaker arm, which pushes the push rod and rotates the wheel hub securing and rotation assembly.

Safety precautions

Never carry out maintenance or adjustments while the machine is running. If something goes wrong, stop the machine immediately and cut the air supply.

Inspect the machine before every use and confirm all parts are securely attached.
Use the correct tools for the size and type of tyre — the wrong tooling can damage the machine or the tyre.
Understand how the machine works and its safety features before operating it. Ask for help if you are unsure.
Keep the work area clean and free of debris and oil, with enough space to move around.
Stay a safe distance from the machine while it is in use.
Maintain the machine with regular cleaning, lubrication and inspection.

Installation procedure

Insert the bracket for mounting the large cylinder (10) into the stabilizing stand (9).
With the bracket secured, insert the bead breaker arm assembly (4), then fit and tighten the screws (11) to secure it.
Insert the large cylinder and foot pedal assembly (2) into the bead breaker arm assembly and secure it at both ends with the screws (12).
Insert the wheel hub securing and rotation assembly (7) into the stand, fit the cone (5) into the wheel hub centre hole and tighten the large nut (6).
Connect the large cylinder and foot pedal assembly to the hub adjustment assembly (1), then insert the push rod assembly (3).

Removing a tyre

Deflate the tyre completely through the valve core.
Push the tyre into the bead breaker arm, then step on the foot pedal. The cylinder pulls the arm and the shovel loosens the tyre from the wheel hub.
Load the wheel, select the matching cone, fit the large nut and secure it with the crescent locking wrench (14).
Install the hub adjustment assembly (1), set the duck head to the wheel size and tighten it with the hex wrench (13).
Insert the tire pry bar (8) above the duck head and lift the upper bead. Extend the shovel arm and cylinder to their maximum position, fit the push bar, and retract the cylinder with the foot pedal — the hub rotates and the upper bead comes off.
Repeat for the lower bead: pry it up above the duck head, extend to maximum, fit the push bar and press the pedal.

Hold the tire pry bar firmly throughout the operation.

Fitting a tyre

Lubricate both beads with tyre mounting paste.
Place the tyre on the rim at an angle with the duck head opposite the valve stem.
Work the lower bead under the duck head and rotate the hub assembly to walk it onto the rim.
Repeat for the upper bead, keeping pressure on the opposite side so the bead stays in the drop-centre.
Inflate to seat the beads, then set the final pressure and refit the valve core.
