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. |

Low profile tires ?
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. |
