Old logic question…Which is more accurate? A clock that runs 10 minutes fast a day or a clock stoped dead at 12 o clock?
Answered: The clock running fast is NEVER right.
The clock stopped at 12 o clock is right twice a day and is the most accurate.
How can you possibly trust your tire gauge?

Buy Milton tire pressure gauges and forget about it.

I bought two Milton pencil gauges not that long ago, USA made, and cheap. But not cheaply made.

My 10 y.o. Milton pencil gauge has been trustworthy for over a decade. Matches the TPMS reading of all three vehicles I have had since purchase. I keep mine stored inside, maybe that helps in consistency of readings. Mine came from the Zon

Well, my Scion specifies 35 psi for the fronts and 32 for the rears, so it should be able to discern 3 psi for sure.
Not sure that's valid. Maybe they want +/- 3 PSI. So front not to drop below 32 and rear not to drop below 29.
I have two cordless tire inflators where you can set the pressure and it will fill and stop at the desired pressure. The Milwaukee M18 fills quicker and stops exactly at the proper pressure. The Ryobi stops at 1 PSI above what is set. I am not sure but kind of guessed you might loose that last pound disconnecting the tire inflators from the valve stem.
One does loose some air even measuring the tire PSI. Not sure how much.

That’s what the door sticker says. I don’t know why.
Just bought another new digital tire gauge because the display on my most recent one is acting up. Was just playing around in the garage today and decided a comparison was in order. Same tire, same time.

I've strayed away from pretty much any digital type as it's hit or miss based on ones I've used. Honestly don't really buy into any particular gauge being the do all/end all with regard to accuracy. As long as it's consistent use after use and the vehicle feels as I expect after an adjustment I'm fine with using whatever.
This is my go-to for yrs now and simply see no need to switch. Very durable, consistent and the tread depth gauge quite convenient.

It’s what I use at work and home.

The ad for this gauge is useless. It boasts "maximum accuracy." Can't beat that.
Get an open flow locking tire chuck. You just pop the chuck on the valve and pop it off, the least amount of air loss possible. Same as using a tire pressure gauge. Once I realized the M18 was accurate I don't check pressures anymore and just turn the inflator on and pop it on. If it's low I inflate.
I just got a JACO ElitePro cause Project Farm said it was most accurate. It's head is very easy to get an airtight seal on, and the hose makes reading the gauge head easy.
It agrees with my TireTek 0-200 PSI gauge.
But my Michelin MN-12279 was off 2 PSI from the others... And is now in the landfill.

The eternal question, "What time is it?"
International Atomic Time (TIA) is based on an average of 450 atomic clocks all over the world. TIA is on a continuous scale without seconds or fractions thereof.
Coordinated Universal Time (UTC), the international time standard that replaced e GMT in 1972, lags 37 seconds behind TIA due to leap seconds.
That is however completely immaterial because you don't know when it is 12 o'clock because your clock is not running - unless time itself has stopped, of course.

I had to throw my 1/2 cent in. (Inflation, no pun intended). In general, a rotary dial pressure gauge with a bourdon tube is most “accurate “ at 50% of scale. That is because if it was calibrated correctly, the linkage arms will be at a 90 degree angle to each other. Accuracy can be divided into 2 parts- repeatability and match to a standard. Most gauges I’ve seen have a percentage tolerance at full scale and a repeatability percentage. You can buy a gauge with .5% accuracy and repeatability, but most folks can’t afford something like that. Temperature can affect a gauge, but from my experience, not too much. I’m sure the manufacturers of tire pressure gauges have NIST traceable measurements available, but one master because having the equipment certified is extremely expensive. All of this being said, repeatability is king. If your gauge reads the same way every time for a given pressure, you can compensate for errors yourself. In industrial settings, we can tell what some of our pressure readings should be by other readings we measure. There are times we know a reading is a bit off, but we leave it be because operations is used to seeing what is there. Hope this gives you some insight into what goes into calibration.
I have a TPMS scan tool and two accurate gauges. One of the accurate ones is digital, the other a dial type that somehow was calibrated off by two lbs and made prior to TPMS sensor use. All my pencil types hit the trash. One pencil type came from GM with a kit for service writers when I worked dealers. No surprise to me that it was off by 5 lbs too low. BTW those pencil guages from GM came to the shop just aboiut 10 yrs ago. At least the brake wear and tire wear gauges were just plastic with no calibration needed.
Tonight I checked tire pressure of the '25 KIA Soul LX . The tire pressure gauge is $11.88 at Walmart . Outdoor temperature was 38 .
Accurate enough . KIA recommends 33 P.S.I. I think I set them to 34 >34.5 .
Purchased 9/24/23 and gets plenty of use . So battery holding up .
