Harbor Freight Tire Changer #34542

(Click images for large one)

Bought this in 2003 for around $39.00 ( Harbor Freight #34542) and it works very well.

You have to drill the concrete floor to install the anchors that the changer bolts down to.

That's an afternoons work in itself, but when you get ready to use it, lay the tire on the base and let the air out by removing the valve.

Once the air is out, have a soapy water solution handy and brush some around each bead

Place the bead breaker right in between the rim and tire.

Let the soluton soak in for a minute, then insert the bar and press down. The outside of the tire will break off pretty easy. The back side always requires a bit more work. I have a tire iron handy to coax things along.
After the beads are broken, place the wheel on the top of the pedestal and locate the lock pin through one of the lug holes.

Drop the star lock over the center pin and spin on the lock tube. this will hold everything tight while you crank off the tire...
Place the flat end of the bar under the bead and pull it over the rim. Then, holding the bar down on the rim edge with one hand, pull the bar around the rim, leveraging on the enter pin.

The tire pops over the rim pretty easy. Once the outside is off, put the bar tip under the rear of the tire and pull it off also.
About 10 minutes from starting time...
New rim NWRA 40273..

Putting the new tire on is the reverse of the first procedure, but you use the other end of the bar, as it has a notch that rides on the rim edge and helps push the tire over the bead edge. Use the soapy water again, it will help. The final 6-10 inches of bead will probably require you to use the flat end of the bar again to pry the tire on.

Once the tire is on loosely, install the new valve

The bottom bead will lay flat on the rim. The upper bead may need some help to seal while you put air in. I use this strap and some hand manipulation around the perimeter. It doesn't take long for the beads to pop in place... Voila!

I heard some Mexicans pour a little gasoline in the tire and slosh it around. Then stand back and flip a match onto the rim......Whoomp, the tire is on the rim..

Awaiting the new shoes......
