My experience would have me proceed with caution.
On their supple tires (esp. extra-light) 60psi in a tire that small would feel pretty soft at my weight (180lbs). So while that sounds reasonable (I run 28mm Conti GP5000TL tires at 60psi no problem), it may not be great
for pavement riding.I've had a TC-labeled Barlow Pass blow off a hookless rim at 50psi, just riding along. That was terrifying and consequences could have been really bad if I had been riding faster, down a hill, etc. Tire had been fine for over a thousand miles before that. Officially RH says their tires are compatible with hookless rims, as I believe Enve did some testing with their own rims, but that is gonna be rim dependent too and I'm skeptical that they've done much to validate this. Especially long-term testing. Anyone that has installed these tires knows they have looser tire beads than much/most of the competition. I realize you didn't say hookless rims, but this experience makes me cautious about pushing the limits of their tires. (I'm not the only one with this experience on hookless rims; I've seen other forum / bikerumor / etc. comments implying similar experience with these tires failing on hookless rims.)
Finally, I'd note that in their own tests, RH concludes that latex tubes are faster than tubeless (with sealant). I take this finding with a bit of skepticism since they seem to be fairly anti-tubeless in general, but also recognize that being anti-tubeless is unpopular and they have made unpopular points before that were proven out. I had such trouble getting my most recent Snoqualmie Pass tires to stay inflated (improper seal at the bead, sealant just wasn't spending enough time around the bead of these massive tires to help seal the imperfections) that I switched to latex tubes. The ride is fantastic. Could I tell in a blind study? I don't know, but if their roll-down test data is to be believed the speed differences were something you'd notice on the bike computer. And it's been nice not having to pump up my tires mid ride
(I've ridden many sets of SP tires, which I have eventually gotten to stay properly inflated tubeless. This time was unlucky, I guess.)
