OK, I get this, but with a TUBE, when you have to really reef on that last bit of bead... that valve is going to get in the way of your hands, and there's a good chance you're going to rip something.

Thumbs pushing on the bead in the middle and palms to the sides are no where near the valve, and with the extra slack you don't need to push that hard.

I've never had a tire be difficult to get over the rim once you get to the end point. It's usually well to either side of the ending point that the bead of the tire stops and seems like it can't possibly go any further. Once you get past those first stopping points, everything gets easier.

Believe it or not, I actually broke one of these things ! Fortunately, since I just bought it, my shop covered me and gave me a new one (I never knew if they got reimbursed themselves, or if they ate that loss.)
I don't think I've had to use it since. The tires I'm currently using on my 3 bikes are all surprisingly easy to re-mount.
Anyway, I can relate to the OP's woes. I've never been so close to walking out side and wrapping something around a telephone pole as I've been when trying to mount a difficult tire ( in fact, some Rubino racing tires way back in the day come to mind). That probably about the most pissed-off I've ever been.

The worst I've ever mounted are Panaracer Paselas on Mavic MA40 rims. I have two examples of this combination, and finally tried the Koolstop Tire Bead Jack. It actually works. All the other suggestions are worthy, and I've tried most of them, but I love my bead jack. Life is too short to fight with mounting stubborn tires. I need to find a way to carry it along on rides. It almost fits under a Brooks saddle, but how to secure it?

Well maybe my technique is a little different - I put my thumbs through the spokes, wrap my fingers over the tire, and pull the bead up from the other side. So the valve would be in the way and vulnerable if that's where I were doing it.

This was my point in criticizing my Bontrager Paradigm Elite rims and R3 tires in tubeless mode: with years of experience (many working in the bike shop) I can't get their darned tires into the rims. I can't imagine using tubeless (or Bontrager tires for that matter) if any attempt to fix a puncture in the field would be impossible.
And IIRC, you're not supposed to use a tire iron or tire lever with tubeless. So they're completely non field serviceable.

Pacenti apparently only a 650b road tire, not 700c.
At least the Koolstop jack is small and light enough to go
into a reasonably sized under seat bag. All of my road tires have a tapered edge to the bead so I can imagine
some difficulty getting the jack edge to snag that bead, but once it did the jack might work. Still have to
watch for tube pinch and the jack, unlike a lever does not push the tube ahead of it. It does look a bit flimsy.
Still need levers to get the tire off the rim, jack no help there.

Got tired of stuck tire tools and pinch flats. So now, I use an old spray bottle filled with water. Partially inflate tube and spray water all over it. Spray water on tire bead. After that, everything just slips & slides together. Plastic tire tools with steel inside help too.

I've only used mine once, but it was nice to have it. I have broken more than my share of Pedro's levers. The new tire I mounted earlier in the week went on with just my hands.

Now that I have a couple of wheelsets with tubeless tires, my old Koolstop tire bead jack has become a permanent resident in my Camelbak. I actually ride regular clincher tires w/tubes more often lately, but it's too much work to move the Koolstop in and out of my backpack just to save a few grams, plus I'm likely to forget to pack it someday when I actually need it, so I just leave it in.

I broke two Pedro's levers today, trying to mount the second bead on an mtb tire. Then I remembered my bead jack. Whoosh. Done.

The bead jacks seem to apply the force in a little more controlled way, or maybe that's just purely subjective because you have so much more leverage so everything feels easier and gentler. Also, because of the way they hook the bead from above, they only need to lift it the minimum amount required to get it over the rim wall. With a lever you need to lift the bead high enough to account for the thickness of the lever too, so that much more force is needed.
