I never expect a tyre to seal up fully til I’ve done a ride on it- quick pelt round the block can do it but not always. As long as it stays up for a few hours, ie long enough to go for a quick ride, I’m happy because after 1 ride it’ll usually be sorted.
What rims is it? Rims are more important than tyres IMO, it’s a long time since i’ve had a quality tyre that wouldn’t bead up and seal but I really don’t like pissing about with non-tubeless rims…
Never had a 2bliss that didn’t work perfectly tbh. For contis (and for used tyres) a bit of glitter in the sealant can make a big difference, sounds like bullshit really but it does work.
