It’s news to me today when a friend of mine told me that the 28mm Conti tires were coming off these rims. And then I looked up zipp’s website and saw the incompatibility. I have this exact combo. Now I have to get some 30mm tires.
What a very cool place the bike industry has ended up in for consumers.

this has been explained a whole big bunch during the first half of this year. there was a kerfluffle about hookless in the spring and the ETRTO decided that its guidance was as follows: if you use a hookless rim with an inner bead width of 25mm you should use a tire with a nominal tire size of at least 29c. so, while the actual data that this is necessary is lacking, there has mostly been a coalescing around this guidance. hence your 28c tire conforming and then, magically, not conforming (since your wheel has a 25mm internal bead width).
not to toot my horn here but i would imagine nobody has more miles on more various hookless road wheels than i do, which is to say, pro cyclists have way more miles than i do on this wheel, but i have miles on this wheel, on the 353 NSW, on the 303 S, 404, several CADEX models, ENVE, and in my workshop are a number of additional hookless tubeless road wheels (forge & bond, etc.). so, what i have are miles on a lot of these kinds of wheels, along with measuring, mounting, dismounting and so on. what my experience caused me to very quickly decide (by sometime in 2020) is that 5 to 7mm of delta between inner bead width and nominal tire size is ideal. so, for your wheel, a 30c tire is dope. (not 30mm, but 30c, which will blow up to 31.5mm on that wheel.)
if you are forced to ride, say, a 30c conti tubeless tire (e.g., a 5000 S TR) you would be riding the tire width, tire brand and tire style (tubeless) on the rim width (25mm) and rim style (hookless) used by a particular guy in the most recent TdF for virtually all of his road stages, and nobody seemed to be able to keep up with that guy.
Pog at the tour isn’t exactly a great example. His frame is objectively bad, yet he still wins. Winning on the tires he did doesn’t mean that’s the optimal solution.

imagine how fast he really is if he’s racing on, as you say, shitty equipment.
