Many years ago I chosed Schwalbes Marathon Plus tyres for my bikes, reason the advertised puncture resistence.
Now I'm about to dump these for another brand and/or model because, in topdown order of annoyancy
1) They are very hard to get off, and also back on, without denting/damaging the rim and the tyre end, risking rubber pieces coming off, exposing the steel wires to rust, and compromising the structural integrity (poof..) of the tyre.
2) I still got 1-2 punctures yearly, most due to nails / schrapnel, and since the antileak compound changed color green>blue, more frequently, even due to stones with a sharper edge, that get like stuck in it, not pushed back out, further cutting till inner tyre leak.
SO I searched around and found some info:
https://www.cyclingweekly.com/reviews/tyres/schwalbe-marathon-plus-tire-review-robust-and-reliable
I got less punctures with the Schwalbe Super-Moto-X tyres that are dead easy to get on/off - even without any tool.
This quite recent (2023) remarkable thread, used on a cargo bike, so similar to my usage, a couple sixpacks 1.5 liters is 18 kg but it happens several times a year that I have double that weight.

There are some interesting reads, Schwalbe has have had a fail design or production, being not enough rubber around the steel wires causing disattachment ("slipping between steel and rubber") quickly (because selfreinforcing) causing the tyre becoming dead easy to put on/off, to such a degree that it happens without trying.
But according to what is said there, that was a problem in a past, that has been solved.
An interesting comment there:
I lost like 45 min this morning to just get one side of the tyre over the rim wall, and used 2 mm stainlees steel plates to prevent denting the rim and plastic/nylon to prevent damaging the rubber. ALL air out, one lever in, turn, hook over spoke, with some effort, succeeds. But that pulls the steel cable out of shortest course, making it even harder to get a second one in.
Years ago I saw a dealer taking it off with a kinda shoe puller 70 cm long I think, in one time, proving that it's all about alot force, and special maybe do it yourself tools, to save time and reduce risk of damage.
It's just silly. I rather prefer 3 punctures yearly that are easy to fix along the road, than 1 that is a walk home despite spare inners and tools that do the job on all other tyres.
At some point one has to say enuf is enuf and look for something else that delivers a better overall, which is what I try here.
Mass tests on the web, about all thing out there in the world, I experienced as bad references.
Good references come from people that used the things many years, upto present day.

That reads nice but for me and others (see below) proved otherwise....Even sharp thumb tacks/drawing pins cannot puncture it - ...

I would say, if a tyre is so hard to mount unmount, risking damage, then the size is NOT correct from the beginning. Reason being steel wire (from what I saw in the past when I damaged one), a cable, too short / not wound to the diameter that means reasonable force to get off/on.It has to be a flaw with the metal bead around the edge. That is the main thing that keeps the tyre edge exactly the right size.
