Thanks for reply. I am working on a hypothesis.
When we check air pressure there is a possibility for the valve core to not seat completely.
Here is a post from my blog
. You can see the example of the slow leak. Metal valve caps with "O" ring seals in good condition might prement some of the air escaping but the cap is not a primary seal only a back-up and should not be depended upon.
I note that a lot of tire run low flex failures seem to occur 30 min to 1 hour after pressure was checked.
A TPMS is the only way to learn if you have an active leak while traveling down the road, especially if the leak is caused by leaking valve core.
