In other words, once a tire had a puncture, it then had to be run 20-30 psi less to avoid a "relapse." For a lighter rider, or someone who prefers lower pressure due to rougher roads, tubeless can work well. For me, on the roads I ride, I wouldn't run tubeless on my road bikes again, unless I went to 28mm tires and stayed at least 10 psi below your nominal 90/80 psi.
Yeah, I have faced that issue as well. Got a flat that sealed during the ride but at a much lower pressure - enough that i felt a bit squirrely on that coming down a long hilly descent. And it wouldnt re-seal at anything more than 50-55psi. I am going to try a different sealant and Dynaplugs to see if that solves the issue. I normally dont flat enough that for me, the tradeoff of dealing with sealant mess is not worth the benefits of tubeless. But if i can simplify the issue of dealing with tubeless flats, that may change the equation.

30mm is the nominal size or measured size?

I'll curse your name then, i guess...
jokes apart, I've already been unhappy with tubeless a few times in the past year or so of trying it - but at the same, i also have to accept that 2 of my tubeless flats were sidewall cuts (which isnt a tubeless thing) and in one, the tire did seal but at a very low pressure that felt wobbly (this is the question i had asked in my other thread). I'm really digging the ride on my RapidAirs, though - enough to make me want to give this whole thing another go.
