I just mount it to the top of my welding table. Its basically my main workbench so that's where I used it when I needed it.interested in the responses. Its getting harder and more expensive to get a shop to mount garden tractor tires.
Those that have one, what do you mount it to?

You need to find someone with experience local to you or watch a lot of youtubes. Tires are funny, if you know the technique, they almost hop onto the wheel, if you fight them, you'll lose everytime. I was lucky, early on I found a guy down the street that gave me some quick pointers, especially about not forcing anything.While we're here...
Any tips for softening up a 4-ply tire to ease installation?
Trying to avoid ruining the bead, like I did on this 2-ply tire:
Granted, that tire had probably seen better days. (I was actually trying to put a tube in it, but the process whooped me and I took my frustration out on the tire, so I gave up and decided to do it "right" and go back tubeless).
Already ordered some tire spoons and Ru-Glyde, thinking of using a heat gun, or trying to let the tire sit in boiling hot water? (Leaving it out in the sun seems to have little to no effect).
