Good morning.
Recently I conducted a search on why, after long-term storage of my car about 5 months, one of my tires pressure was 4psi lower than the others. I had set them all a little high, 40psi for storage.
Upon returning, three of them had dropped to 35psi - the weather was colder - but one was at 32.
Google results included the obvious - a tire puncture, but I think that tire would have been flat after 5 months storage. They also suggested checking the vaves and the stem cores.
So I purchased a 4-in-one tire tool, and using the valve stem core side I checked the cores.
I turned them initially counter-clockwise just a hair, and they started hissing air. I mean, they were loose, it was no effort for me to turn either direction. Is it possible for them to loosen over time, due to temp. swings, etc.?
So I tightened them all by feel until they felt reasonably tight without hamfisting them. That was about the best $4 I spent spent in a long time!
Next morning, I set all pressures with a digital gauge, ‘33.0’ psi
We’ll see in two weeks, if they’re all exacty the same pressure (33.7 or 34.1 or whatever, with the same gauge) by then, then my efforts fixed the inconsistency.
I hope this information is helpful to even one reader, and nobody take offense to it.
