>>1652459I define modern as something that's been released in the last few years. Rubber compounds and construction techniques continue to improve and can be used to improve puncture resistance for racing tires without compromising rolling resistance, handling, or ride comfort. I have gp5ks on another bike and compared to the 4k s2 they're far better, because Conti made a lot of improvements in their compound and construction. The same goes for the TCs with respect to older Vittoria open tubulars. Of course, newer doesn't always mean better. The Pana graveling slicks that I have on yet another bike are a step back compared even to Pasela TG/PTs.
Tubeless tires are clinchers, too. Saying that you moved away from clinchers implies that you're rolling on tubulars. Also, how long have you been running road tubeless? The GP4s are decade-old tires now. They were replaced by the s2, what, 5 years ago? Anyway, blowouts can be a problem for tubeless tires run at higher pressures, particularly if you have rim brakes and heat up the rim on descents. It can be due to a poorly manufactured rim, or a bad interface between rim hook and tire bead. This is more of a problem with carbon wheels than aluminum, and can happen with tubed clinchers, although I don't know if the failure is as catastrophic as it is with tubeless. Anyway, it's not the fictional concern that you think it is, it's something that has happened to a lot of people.
Another problem with road tubeless is that they often fail to seal punctures because pressure is too high, so the sealant just sprays out and then you have to put a tube inside of a tire that's covered with jizz inside.
