I only run latex tubes on TT wheels. Too faffy for anything else. Lose lots per day.
Cheap Butyl on everything else. Lose fuck all per day.
Tubeless still sitting untouched in my Fear of Change room. Middle ground.
I'd say my S-Ones lose about 10 Psi a week too. But my cross bike used to lose way more with several tires. Commuted on it in some really rough paths, so maybe it depends on the usage too? Or just the tire/rim interference, who knows.
That matches what I've seen with the Pro One I've had sitting there in my lounge. With sealant it should lose even less?
