Autos: tire pressure gauges: the three-gauge scenario

Self-tutoring about autos: the tutor visits an ongoing saga with tire pressure gauges.

As I mention in a post a few days back, I recently found a digital pressure gauge I lost so long ago, I’d forgotten about it. I replaced its long-dead cell, tested it, and realized it seemed to work.

Tire pressure gauge accuracy has been a theme for me, as I mention in my post here. I’ve got two other pressure gauges, both being the traditional mechanical kind where the scale pops out to show the pressure. One is from a long time ago; the other, purchased last summer. The newer one consistently reads five psi less than the older one. I haven’t known which one to trust.

Yet, with the arrival of the digital one, I could perhaps clarify the situation. It turns out that the digital one agrees, almost exactly, with the newer one. I’ve decided, for now, to trust them, so pumped up the tires accordingly.

I mentioned this situation to the drivers of those vehicles: we’ll see if they notice anything.
