I needed to change the rear tire on my ET4. In the past I had used manual tire irons and wanted a quicker and non-marring way.
I bought the Harbor Freight Mini Tire Changer for $29.00 (on sale) and the No-Mar Mounting/de-mounting bar for $99.00.
The No-Mar Bar also came with extra tips and lube.
The picture below shows the four holes I put into my garage floor with a hammer drill and installed 4 threaded drop-in anchors.
I got the drop-in threaded anchors from Lowes.
The Harbor Freight Tire Changer was then bolted to the floor.
Mount the deflated ET4 tire onto the Tire Changer and use the bead breaker bar to break the bead.
Flip the tire over on the Tire Changer and break the other bead.
Flip the wheel back on the Tire Changer with the shiny side up. Spray lube between the rim and the tire bead.
Insert the No-Mar demount bar as shown below. An rotate the bar until the top bead is off of the rim.
Pull the tire up and insert the demount bar as shown being sure to spray plenty of lube to allow the second bead to slip off the rim.
Clean the spray lube from the rim with a rag.
Use the paste lube to lube the inside edge of the bead from 10:00 o'clock to the 2:00 o'clock position.
Push the lubed tire onto the rim as far as you can and keep the bottom bead in the middle of the rim.
Keeping the tire valve at about the 2:00 o'clock position.
Using the Harbor Freight mounting bar, roll around the rim pinching the first bead onto the rim.
Lube the top bead in the 10 to 2 o'clock position and use the mounting bar by pinching the bead over the rim.
Be sure to hold the bead that is below the rim in the middle of the rim.
This will give enough space for the bead above the rim to snap over the last bit of rim with the mounting bar.
Without inserting the the valve core, blow the tire up to assure both beads are seated on the rim fully.
About 30 to 40 PSI should do it.
Watch you fingers when doing this.
You will likely hear a pop confirming proper seating of the beads.
Allow all the air to exhaust from the tire and insert the tire valve core and re-inflate to the proper pressure.
Replace the Valve cap and remove the tire from the Tire Changer.
Unbolt the Tire Changer and store out of the way.
I wasn't able to use the No-Mar bar for mounting the scooter tire.
The No-Mar mounting end was too large to fit inside the smaller scooter tire.
The Harbor Freight mounting bar worked well. However, I did mount a plastic cover
on the Harbor Freight bar to keep from scraping the rim edge when
mounting the tire.
MODIFICATIONS TO THE HARBOR FREIGHT TIRE CHANGER BAR
Below shows how I modified the Harbor Freight Mounting Bar with rim protectors to help
prevent any scratching of rims. Rim protectors can be purchased from many sources.
Here is just a few.
Rim Protectors and Harbor Freight Mounting Bar
Using a bandsaw and a utility knife, I shaped the rim protectors to fit the shape of the
Harbor Freight Mounting Bar.
Cut Rim Protectors to Fit Mounting Bar
I drilled 1/8" holes in the top side of the rim protectors and mounting bar but not through
the other half of the rim protectors. I used four 1/8" pop rivets (two for each rim protector)
to attach the rim protectors.
Pop Rivet Rim Protectors to Mounting Bar
This is a contact tip from No-Mar that I intent to mount on the demounting end of the
Harbor Freight Bar. More on how to do that later.

Comments from others about the Harbor Freight Motorcycle Tire Changer. Not the Mini Tire Changer.
Now you have a ready to install tire and rim for your scoot.
But what do you do with the old tire?
If you have a miniature Tug Boat... that's a great place for old scoot tires.
They make great fenders!
