We're seeing progressively wider rims that end up pulling the sidewalls of the tire out and the depth of the tire is reduced. In these cases you should use wider tires to obtain a normal profile.

Interesting.

My HED Ardennes 23SL wheels are 23mm and are designed for 23mm tires.
The current model Ardennses Plus are 25mm and as far as I know they are
designed for 25mm tires.

That is the ISO chart, that favors putting relatively wide tires on
narrow rims for testing and for their 'official' sizing definition. I'd
love to see ISO's reasoning for this, but it isn't publicly stated. It
might be in their standards copy, but that costs $200 or whatever to
look at.

Note that for pretty much any other kind of tire, you would never mount
a tire that had a width that was 2X the rim's bead with. Tires on cars,
trucks, ATV, motorcycles, tractors or airplanes is rarely more than
about 1.25 times the rim with at the most.

The current trend among road bikes is the other direction, with the
tire's stated width nearly the same or even less than the rim's outside
width. If this causes any problems, nobody doing it seems to have
noticed yet.

The 'stated' is constrained by liability advising engineering.

There are trends

And here suspicions arise due to more various apps like gravel low profile

filled with more riders and LCD

Poss oblivious to a short sidewall is limiting.

It is my understanding that the HED wheels you are talking about are
designed to run with a specific size tire solely for aerodynamic
reasons in order to minimize drag caused by where air coming off the
tire first reattaches.
https://intheknowcycling.com/2016/04...s-wheel-sizes/

If your concern is the lowest possible drag then I assume that using
HED recommended tire sizes is important.

Yup. I read the site and then I read

Which tells me that:

"If the tech sheet, marketing copy, and glowing reviews from major
publications aren't enough to sell you on the plush, efficient ride of
HED's Ardennes Plus SL Road Wheelset, then just head to your local
two-wheeled hotspot and count the number of times you see that
unmistakable branding roll by on everything from carbon race frames to
steel touring machines with wheelbases you can measure in meters. This
ubiquity is no accident."

Then I got to thinking that I've never seen a "HED's Ardennes Plus SL
Road Wheelset", never. So I just assigned the claims for HED to the
container labeled "Outrageous and unproven claims".

Well, if they were white or partly white they certainly weren't
"tactical tires" as everyone knows that the word "tactical" actually
means black.

Whatever. If you want to think people use the same tire width as the rim
width because of some aero fettish, that's up to you.

As for what you've seen I can't argue but they're popular here on Québec
roads.
