I gave up on tire gauges years ago. I can thump a tire, which is hit it
with my fist, and tell by the sound when it's at the proper level. When
checked with a gauge, I'm always nearly exact to the proper inflation.
Of course this is something that you cant just learn. But in my older
age, I just know the right sound. Tire gauges are cheap, but no matter
where you put them, they are never found when needed it seems.

I'd be willing to put that to a controlled test/demonstration...

With truck tires I could usually pick up a tire that was 10 to 20 pounds low
by thumping. They were 110 psi tires and you were thumping two side by side
so you had an immediate comparison unless both were low.

Down 40 pounds or so almost anyone would pick up the duller sound. As for
exactly 110 psi, I definitely wasn't that good.
