Since I didn't want my NoMar permanently affixed to the floor (commitment issues), I had them cut me a nice steel plate to mount it on, and I can slide it where I want it.
No-Mar sells a kit to affix the changing stand to a 2" receiver hitch. Else one could build a pallet of wood to screw it down.
I've done car tires, trailer tires, ATV tires... but I still prefer my pool bucket and tire tools for my dirt bike tires. For some reason, I haven't found the magic of swapping tires with tubes - always screwing the tube.
In the mid 1970's I worked summers and weekends at a dealership and did most of the tire work once they found I didn't pinch tubes. Still, I got the spoked steel rim jobs and one of the full time mechanics did the very rare "mag" wheel.
The trick is one has to "think like a tube" no matter you can't see it most of the time.
Only in the last few months I was there did we have anything like a proper tire changing stand. It was a simple post bolted to concrete with a ring covered with a split garden hose. A post up the middle that was small enough to pass through any wheel. And a pry bar with a shaped tip to follow the rim and guide the tire over. It was wonderful!
We had one other thing I haven't found or bothered to make since: a valve stem snake. A brake or clutch cable with a threaded fitting to replace the Schrader valve core. Unlike those we see for sale today that have a cap that screws on the outside this went inside and would pull a valve stem through any hole a valve stem would fit.
I've seen those but as a mechanical engineer who has busted spokes on dirtbikes in the past I fret about the very small nick the setscrew makes on spokes. I'd much rather nick the nipple than the stressed spoke. Wish I had kept some good old lead weights which clamp over the spoke nipple. Am very nearly talked into using stick-on weights to counter the rimlock.
I also like to take my time and bust the tires at my own pace. Or when Trainwreck needs tires changed, he brings me beer. That works good too.
I got one beer, a frozen pizza and 2 liter bottle of Coke for mounting a friend's tire.
It was interesting, 16" steel rim, spokes, tube, off a Kawasaki cruiser with shaft drive. Short dirtbike spoons and Tusk rim protectors were just the right thing to get the last part over the rim. Am thankful the rim was at reasonable height and clamped down while I was working on it. The long Delrin-tipped No-Mar tool levered against the center post of the CH200 was the right thing to get the tire off but I've been much less successful using the 2-tipped end to mount tires.
