I changed my own rear tire, with a Cycle Hill, No-Mar tire changer. It was definately an interesting, challenging, educational, first time, experience. The instructions, that came with the changer, (on "tire changing techniques"), are well written. I used it step by step during the change. However, I should have watched the supplied DVD, that came with the changer, because I missed some valuable information, by not doing so at first.
Once, I locked the wheel onto the changer, the old tire removal part, was really easy. No problems there. I put the new tire over the rim, & the bottom lip of the new tire, went onto the rim fairly easy as well. Oh yea, going good! The only thing left, was to get the top lip of the tire, beneath the top lip of the rim.
Where I went wrong: I proceeded to mount the tire, with the demount bar. It appeared to be going well, to about half way around the tire. As I would hold the tire down, with my left hand (as the instructions said), while pulling the bar around, & at the same time pushing it around, with my hip, I just couldn't keep the backside of the tire to stay beneath the top lip of the rim. Now I'm getting frustrated ??? And almost regretting buying the changer, in the first place
So I took a break, and decided to call No-Mar.
I got a woman on the phone (I should have gotten her name). I told her, what was happening, & she immediately said, "I know exactly what is happening". She said, "we face this issue all the time, & have changed many sport bike tires down in daytona". The key technique I was missing (which was not well explained in the paper instructions, but is clearly illustrated on the DVD), was to push down fairly hard on the tire, with the left hand, so that it locks itself under the "bead" that's on the flat part of the rim (on the inside, not the top lip). When I did that, and started pulling the mounting bar around, sure enough, the tire was locking itself (or staying), in that position. I got the bar all the way around, to about a little less than a quarter of the way, before it got really stiff & hard to pull. I then used a long handled screw driver (the wrong tool for the job), that I wrapped in duct tape, to keep from scratching the rim, to pull the remaining lip of the tire, over & under the top lip of the rim. No-Mar sells a 16" tire iron, that I should have ordered, with the changer. I'll get one before the next tire change for sure. Big thanks to No-Mar for such a well made product, & great support 
.
That was it. I poured 2ozs of Dynabeads, with the supplied applicator, through the valve stem. Screwed the stem back on, & 42psi of air pressure later, I reinstalled the wheel onto the bike
. Front tire is next & I'm ready.
