Do hard to get on tires get easier if you take off and put back on?

IME, they do seem to get somewhat easier.
But since Murphy's Law dictates that you'll get flats on cold rainy nights, I don't count on any improvement. I'm happy if they don't get worse.

The bead stretches a bit. Rubber covering the bead wears down slightly every time the tire is mounted and removed. Makes it a bit easier. The wire bead Vittoria Zaffiros and folding bead Schwalbe Ones got easier to remount the second time after fixing flats or changing tubes, although the rim strip was a big factor.
My oldest tires, a set of 2008 or so Specialized Hemispheres, fit so loosely I don't use 'em anymore. When uninflated they flop right off the hybrid bike's rims. They're fine inflated and ridden, but it's a PITA that I can't even roll the bike a few feet off the road on uninflated tires without the tire and tube flopping off the rim. I keep 'em in the closet as spares in case a broke friend or neighbor needs tires.

From 2010. I posted details on my difficult tire method. It's easy with the right technique and well designed tire levers.
I commented in another thread:
I commented in another thread:
I had sore fingers and mangled levers with my new rims. The key for me was lifting just an inch of bead at a time, then sliding the lever over and repeating. It's actually quite easy and doesn't need a strong lever. I do think that levers shaped to let the bead slide down to the rim work better.

In my experience, no, they don't get easier.
I also do not understand the notion of "bead stretch."

Yes, they get easier. I don't know the reason but in my experience older tires become easier to remove and replace.

Everything, as it ages, gets looser. You've perhaps heard of the term incontinence? Not that I, at my age, know of such things first hand. I hear tell.

But the OP didn't ask about poetry or posteriors and we are now so far off topic it can scarcely be seen from here.

Point taken. But, let us just say that we are exploring the question from all angles, because, as Heraclitus once said so poignantly, the hidden harmony is better than the obvious.

Beads absolutely do stretch under tension, especially plastic ones like Kevlar. It is really very simple. Tension is the pulling on an object. Over a certain range of tension, the stretching which occurs is elastic. The molecules are being stretched, but they spring back when the tension is released. But even in the elastic range, over long time, some irreversible stretching occurs. Basically the molecules of the material slip and travel past each other. They are being pulled apart. It is called creep. That is one of the reasons they need to start out so tight. Creep is a natural response of many materials to stress.

Also get a VAR tire lever/tire jack. It is small enough to carry on the road. It never fails to get a tire mounted, even new, and it doesn't damage the rim, tire, or tube...if there is one.

Either mine get easier or putting them on makes me stronger.

Honestly...I've found that skipping levers not only is safer...but ends up being easier when all is said and done. Provided you've got reasonably strong hands. There's of course a million articles/videos on it...but IMO a bit of finesse goes a lot farther than a tire lever.

Should get much easier after a few hundred miles. Make sure you start to remove them at the valve stem, so you can get the bead opposite the stem as deeply into the V section of the rim as possible. Same when installing. Leave the valve stem area for last.
