So how did the stauns go? I'm getting ready to get mine and I am curious if I should tackle the install by myself
Well... have you ever mounted a tire by hand before? I've done hundreds... and thousands with machines. I've installed tires for just about everything, 44" Swampers, tons of drag car tires, grader/loader/backhoe tires, semi tires, etc. I have actually installed something very similar to a Staun years ago, for a drag car. That being said, it took me about an hour for each wheel/tire/Staun combo. And I bent one of my Harbor Freight tire irons.
Since you use a tube with the Staun, their instructions direct you not to use any lube to set the beads, or just use straight water since it will evaporate. You need to spread chalk (or baby powder, thats what I used since the chalk bag was kind of small) all over the tube & inside the Staun. This will prevent the tube from folding & tearing as it's inflated. It's very important that nothing gets the tube wet or you will blow the tube.
I used baby powder on the beads too & while it's a PITA, it is doable. Once you get the first bead on, you insert the first bead of the Staun over the wheel, inside the tire. Then the tube goes inside the Staun, then the 2nd bead of the Staun. After that, install the 2nd tire bead once the flap is lined up around the valve stem. Then you have to alternate between inflating the Staun & the tire, to seat the bead of the tire. I got a good deal of air in the Staun (don't go over 50 PSI), then inflated the tire the rest of the way to seat the bead. It's kind of nerve racking and you have to remember that the tube is much smaller than the tire, so it gets to 50 PSI much faster. Get the tube over 50 PSI & you risk popping it.
IMO, I wouldn't trust the 18 yr old punk at the tire store with a Staun install, so I did them myself. I did it all on my own and while 2 pair of hands could be handy with inserting the tube/Staun, there's not a ton of room.
I have 2 more to do (I got one package with a 16" Staun, though it was marked 17". I'm waiting on my replacement 17") and by the time I fought with that wrong size, I was to tired to finish the other one. I was planning on doing a full writeup with pics, but unless that happens tomorrow, it'll be a week out.
Something to think about... the replacement valve stem Staun provides for your tire is metal. They will break if a rock gets ahold of them & would be a PITA to replace on the trail, with the Staun installed. I welded up the original valve stem hole, then put both the Staun valve stem & the tire valve stem on the backside of the wheel. With 17" wheels, both valve stems clear the brake parts with plenty of room.
