Guys just how accurate are these things - just asking because the car readings and my tire gauge are not even close - can't swear that the tire gauge is right at this point - so?

Mine are usually pretty close to spot on

If you rotate tires and not reset the tpms, the readings will also be off

Yea this. Make sure the tire you are checking is actually assigned to the TPMS sensor that you are checking.

Mine always match the actual pressures.

As already stated it is very important to know which sensor you are comparing to. I made the mistake of assuming that mine were correct because the LF was. In actuality the LF was the only correct sensor assignment and the other 3 were wrong. As for accuracy, my sensors are within 1psi +/- of gauges.

...and never rule out that your gauge is faulty...I had two analog tire gauges in two vehicles...bought at the same time and same make and model with good reviews for their quality...I was having this issue where I also thought the TPMS was wrong and when I checked the same tires with the other analog tire gauge I learned one of my tire gauges read every tire 4-5 lbs higher than was actually there...confirmed with a third gauge that was digital...

Unfortunately almost all mechanical dial gauges use a bourdon tube and cannot be made accurate cheaply. Stick and digital gauges are much closer.

We should "roll" this into a tire gauge recommendation thread.

Save it - I just got back from my favorite Auto Zone with a Slime Digital gauge and all is good - throwing all the others away - I'm pretty o'school and have had these old ones forever - received most from car shows goody bags - LOL. Thanks all.

Good update, thanks for following up. FWIW, I use a Craftsman stick inflator with the red rubber hose. Same as 1:46 in video. Exactly matches our two cars TPMS.

I don't have a digital gauge, own 4 oldschool (no offense, Jay ) manual types that read the same as my onboard display, but I'm on Amazon right now shopping.

Reading these threads always costs me money.

I have a whole bunch of them too. This the latest one that I have and I love it. You have to let it settle for a few seconds after filling up since it'll drop a few tenths of a psi, but other than that it's very accurate.

What does something like that cost - and where did you get it - thanks.

 

[Padgett]

Looks good. I particularly like the lock onto the valve stem. Are the batteries replaceable ?

I got it from Woot.com (Amazon's daily deal/clearance site) about a year ago for about $20. Looks like it's still on amazon though for $25:

Yep, takes 2 AAA batteries, the cover pops right off the back.

I wasn't too sure how long it was going to last, the plastic part where the display is definitely has a "made in china" feel to to it, but the rest of it seems solid. I've used it regularly for the last year with no problems.

Thanks, Dave- yours will make my list.
Anybody else have any recommendations?

I had read in the past that those made by Accurtire have performed well in tests https://www.amazon.com/Accutire-MS-...re+tire+gauge&qid=1554116540&s=gateway&sr=8-4 and use this type (mine is older and an LCD version) on occasion...

I got one very similar from Griots. Excellent, and the batteries are replaceable.

Use what you have. Save your money, retire early.

I've got an Amazon giftcard to use and I like the idea of having my tire gauge in line with my compressor hose.
I probably won't live long enough to retire anyway.
