Normal overnight PSI loss for tubeless setup
Those of you who are running a tubeless setup with Orange Seal, what (if any) air/PSI are you losing from your tyres on an overnight basis? Thank you.

Ok, sounds like my wheels/tyres are in range. Thank you.

Interesting that tubeless looses so much overnight. I was thinking of switching to tubeless from my current setup of latex and GP4000. Thinking that tubeless would have the added benefit over latex tubes of not losing so much air. Guess not. Will be sticking with Latex tubes on the road since that is really my only complaint with them. I do not live in an area where we see lots of punctures that a tubeless would benefit me.

But yes, you're making the right decision - going tubeless in the hopes of airing up less frequently would be one of the silly justifications that I've heard.

Basically what you have to keep in mind is that any pressure gauge has to remove air from your tire in order to measure air pressure. Using your pump to measure air pressure means that you have to inflate the pump hose to measure tire pressure which will reduce tire pressure. For a narrow high pressure tire, attaching your pump could easily reduce tire pressure by 5 psi. A small tire pressure gauge might not reduce tire pressure as much. My experience with road tubeless tires has been exclusively with Campagnolo Shamal 2way fit wheels and Hutchinson road tubeless tires, starting out years ago with Fusion 2 tubeless tires. I now have Fusion5 road tubeless tires which I use very often without sealant. They hold air almost as well as butyl inner tubes and better than the latex tubes on my other bike with the non tubeless version of the same tires. One advantage to road tubeless tires is that they are almost immune to pinch flats, particularly if you use sealant.
Every time you check your tire pressure, you reduce it, especially for high pressure road tires

@noodle soup yeah, that makes sense. That's pretty much what I'm seeing too.

Non omnino gravis
Another chime in to say 3-5psi per day, "bottoming out" at ~75psi. This is for 700x25 road tires. Starting lower, they lose less. My 700x35 drop just 1-2psi per day starting from 60psi, and don't generally get below 50psi at all.
But I air up before every ride, so it's a non-issue. Unless a tire is dropping +15psi overnight, it's not a problem.

About 5 psi. Maybe 10. I don't pay close attention. I mean I top them off before every ride, I just don't really look at where they started in relation to when I was last on the bike. So don't trust my number too much.

Well my front tyre lost approx 20~25 PSI between ending a ride on Saturday and taking it out for a ride on Monday night. There was a long road trip where the bike was on a platform bike rack between those rides. To me, that seems like a lot of air loss. I wonder if I have a small puncture in my tyre.

Sometimes people screw the entire valve in too tight, and it doesn't seal well. Try releasing the air, and reset the valve onto the rim.

Thanks folks! I'll take a look at the core tonight. Don't know why I never thought of that!

@noodle soup and @WhyFi I just wanted to circle back and let you know that I took the valve core out, cleaned it up as best I could, and then re-inserted it. This seems to have solved my air loss problem. So thank you both very much! Cheers.
