Something I wanted for years but couldn't find was the VAR 425 tire lever set. It would make fitting, and removing, the Schwalbe Marathon Plus (and Bontrager workalike) tyres that I used until about ten years ago a doddle.
No, it wouldn't, Andre, not if the tires are very wide at all. That's why VAR's description says, "...REMOVING LEVER FOR TIRES OF SMALL SIZE: WOLBER, MICHELIN".
I have three of them for my skinny-tired bikes and I can assure you while they work fantastically as tire bead jacks (the true technical term) for narrow tires on narrow rims, they just aren't as suitable for wider tires except when used as "regular" tire levers (there's one on the end of the jack and a second, standalone lever that stores inside the jack); they excel in that function as they are wide and the hook is narrow and shallow but abrupt without being sharp. The 425 is made of reinforced nylon and
works superbly so long as the "jaws" clear the tire's section width and the rim is not too wide. If neither of those conditions obtain, it isn't worth beans as a jack (I've tried, 'won't work or work well enough to make a positive difference especially if the tire is much wider than the rim). The VAR 425 was the only means I ever found to remove an undersized kevlar beaded vintage Michelin Elan tire from an oversized Weinmann Concave rim back in the day -- and it did it quickly and easily without damage to either tire bead or rim.
The successor to the original 425 is still available but has some detail changes and is now colored blue instead of the older cream color of mine, all purchased before 1983. The basic dimensions are the same as my old version and their geometry remains poor when used with wider tires, which tend to spread the jaws so the notched foot slips off the far rim and the bead hook cannot retain its hold under the pressure of levering. If all is narrow, then it works better for the task than anything I've found. I've had no luck using mine with tires 35-37mm wide and just managed with 32mm, but the jack portion isn't really needed for that. It excels for tires ranging from 22-25mm wide where the tolerances are so tight conventional levers can't really get in to the places needed to do the job. The jack's hook manages by lifting the bead next to the rim sidewall where further pressure just slides the bead across the hook so it can then drop into place. For the right application, it is genius.
There's a video of someone using the VAR tool here:
https://www.youtube.com/watch?v=-OF2t2LJ6Tw...but the gentleman is not using it entirely correctly or as intended. The way to do it is to use the tire lever portions to unseat the beads initially, then use the
rounded end of the detachable lever to "zip" (progressively unseat) the remaining bead. The rounded end prevents bead damage, while doing the same with the hooked end as the video shows can cause bead damage. When mounting, the proper procedure is to engage the bead manually as far as possible, then do most of the rest with the tire lever-ends,
using the bead jack for the last portion where clearances are too tight to fit a lever. Again, "zipping" the bead into place with the hooked ends of the VAR tire levers or the bead jack can cause separation of the wrap containing the bead itself.
If you want the updated version of the VAR tool, it can be found at SJS Cycles:
https://www.sjscycles.co.uk/tools/var-tyre-levers/?geoc=US The lever portion is so good you should get it even if the bead jack portion is not so usable on wider tires. Better, I'd suggest laying in several against the day when you lose yours or someone nicks it.
Kool-Stop makes a version of the tire jack from black-colored, glass-reinforced nylon that is much heavier duty and has a wider jaw opening but still carries the same caveats wrt against use with wider tires. I no longer have mine as I felt it was too large to carry on the bike. One end looks like a bicycle handlebar grip while the hooks are more robust, essentially the same as the old Simson Tyre Mate:
