I had used 4 different tire pressure gauges and obtained 4 different readings. I had heard good things about the Accutire gauge, so that became #5. I got out my Viair 400RV air compressor and decided to find out which was most accurate. But first, I compared each reading to my TPMS. The reading from the Accutire was identical to that of the TPMS. Of course, "two wrongs don't make a right." I then compared the Accutire to the internal TPMS readings in my Acadia. Again, the Accutire agreed with the TPMS. Ok, now am 95% convinced I have a winner. However, I wanted to compare the reading of the Accutire with readings from my other 4 gauges after checking all 6 Goodyear G670's on my MH.

TPMS 105 psi

Accutire digital 105 psi
Slime analog 104 psi
Milton pencil analog 102 psi
Viair air gun analog 110 psi
No-name digital 98 psi

I was chagrined to find out that the analog gauge on the air gun which came with my expensive Viair compressor was off by 5 psi.

From right to left: Accutire, Slime analog w/extension, Milton pencil, Viair air gun, no-name digital.

I am now using the Accutire as my go-to gauge. It is $13.24 each or a two-pack for $24 on Amazon.

if you have a speedco nearby they will test your gauge so there is no guess work. i have found the ones sold by alcoa wheels to be the most accurate.

I use the Astro 3018 on the end of my Viair. Haven't run a bunch of tests but seems like it's +-3psi from my TireMinder TPMS. I like the ease of use it offers.

Why do u call the last one no name? Isn't it also a Accutire?

Thanks, Les. I remember seeing that one at Amazon some time back. Maybe I will swap out the one that came with the Viair for the Astro.

I have owned it for several years and do not recall the name and there is no brand name on the gauge. You are referring to the one on the far left, correct? The one on the far right is the Accutire.

les.warden · 02-20-2017, 03:21 PM

Swapping..Yea, that's what I did. The one that came with my Viair is (from your pictures) the one that looks like a paint sprayer handle.

Drats, I should read all of the responses and not respond one by one. Sorry I missed yours.

parkerbill · 02-20-2017, 04:19 PM

I have the Accutire and it also reads the same or within 1psi of my TPMS.

Petersr58 · 02-20-2017, 04:57 PM

All this means nothing. Until you have a calibrated master gauge you are only assuming. Who says the TPMS is accurate?

soonerdave · 02-20-2017, 05:15 PM

Tire-Minder digital is the most accurate gauge I have found. Had it tested twice against a MASTER gauge and it was never more than 0.5 psi off from 20-120 psi, I have a friend who does gauge calibrations. Is one psi really going to make that much difference, don't think so unless you're the tire guy in NASCAR!

parkerbill · 02-20-2017, 05:22 PM

While you are totally correct I think the point is if you have two or three gauges and TPMS reading very close to each other you're probably close enough. Wouldn't you agree?

I agree, used a digital gauge in the past, however the digital readout drove me crazy trying to get all the tires equal. On the dial gauge, "Close enough for Government Work".
