Tire Pressure Gauge

What does everyone use to check tire pressure? I have several gauges, but each one reads differently. I am really looking for a good, and accurate, gauge to check my tires with.

Overboard maybe ? I just bought one of these after having gone through a couple less expensive ones. My buddy has one I had to borrow when mine **** the bed and the quality can be felt and observed when used so I bit the bullet. https://www.ogracing.com/products/lo...ntent=Catchall \

^^^ Longacre makes a good gauge.

I bought the exact same gauge and it's quite horrible; very inaccurate and tedious. it may be user error, but on the same tire it can read 60psi and then 25 psi thirty seconds later with no changes whatsoever. the gauge has not been dropped i went back to my 15 yr old handheld which at least reads consistently 4 psi too high

Porsche Classic tire Gauge. works great looks great https://www.suncoastparts.com/produc...xoCcSgQAvD_BwE

It's funny how everything is relative. If I had seen the $57 Porsche tire gauge first, I would have laughed at how ridiculous that was! How absurd! $57!! But, the $80 tire gauge was posted first. So, looking at the Porsche gauge my first reaction was... "Huh, $57, that seems reasonable!" (I do understand that quality and accuracy cost money. I'm sure they're worth it, in general.)

I have an intercomp 2.5 and 4.0 which I have used for 20 years. Keep the 4.0 in my 996 to use at the track because it's bigger and easier to read if you are in a hurry and keep my 2.5 in my suv for use in my daily driver. https://www.northstarmotorsports.com...2/Tire+Gauges/

First you have to decide the accuracy you want. That will determine the price range ..Accuracy ranges from .1% to 2% Then Digital vs Analogue Then Liquid filled Analogue vs dry Analogue . Then gauge diameter...bigger costs more... Price ranges from $30 to $300 .. Moroso was the only game in town for PRO tire pressure gauges for decades. Every racer had a Moroso TPG hanging out of their back pocket...And they still have a complete line-up of TPG's from garage quality to Track quality... But they are no longer the only game in town ,many good competitors in the game now.. That said, buy a good aftermarket TPMS like Schrader .. You will thank me later.....Even checking your tire pressure every morning with a high quality TPG with an accuracy of .1% will not help if you pick up a nail mid-day and ruin a $400 dollar tire !!

I’ve always said the key with tire gauges is to use the same one all the time, and never someone else’s. If 41psi is the sweet spot for my tire, on my gauge...that’s all I care about. Higher or lower than sweet spot. Key is consistency of reading. I have a Longacre digital that is very consistent. It’s about 1.5 psi higher than my Milwaukee pump, but always the same.

So the $4 plastic gauge I bought at some gas station 15 years ago? ... not accurate then?

^^^ This All depends on how you define accuracy, speed in measuring, if you want the ability to decrease tire pressure quickly with a release valve etc. I've used intercomp 2.5 and 4 for 20 years. They are consistency regardless of temperature. Certainly not as accurate down to the decimal points as a digital gauge. But after going thru a couple of sets of tires each year with various track tires and every 5 years or so with street tires, you get to know wear and characteristics at different pressures on a gauge you have used forever. Not to mention the convenience when you are at the track to measure before and after pressures and the ability to decrease pressure quickly with a valve right before you go on the track while wearing a helmet and hans device. This is where a big 4 gauge comes in. All comes down to your objectives.

I got a Longacre digital gauge many years ago. I've replaced the battery once. Reads in 1/2 pound increments, good enough for my needs. It's very very consistent. I use it as my 'standard' and rank everything else based on comparison to it. For example I just picked up a DeWalt portable tire/etc. inflator, and it reads 1 pound higher than the Longacre. So I set the target pressure 1 pound lower, because the Longacre says so. (The DeWalt is a very nice tool by the way.)

I bought this one about 6 years ago, I’m happy with it and it’s not very expensive.

Well, you paid too much for it...lol......Those are $0.30 from China if you buy a box of them.....Motorcycle shops around here put their name/logo on them and give them away for free...They are more accurate than you would think and much better than nothing !!! I have had many many TPG's over 45 years and bought this one from Matco in 2007 when TPMS became mandated...It is very nice for TPMS, has a hands free chuck, can read pressure , inflate/deflate to .5 psi at the lever...Pull the lever a little deflates, pull the lever a lot inflates... When TPMS was introduced (and Porsche people they way they are ( ****)) it was a real pain in the ***....As standard procedure we set tire pressures at max load pressures every time the car is serviced unless requested otherwise...( because it is safe and we have no idea if the customer is fixing to go on a long trip with full load/people/luggage) .. then people would complain and want the tire pressure reset/adjusted. Sometimes they would just be upset because one tire would change by 1 psi while the other side didn't...It was a constant annoying thing to keep adjusting tire pressures at whims sometimes several times on the same car.. I remember one day I was sick of TPMS, and low and behold here comes the GM , the assistant GM, a salesman, and a customer pulling in with a TPMS pressure issue...( just needed pressure set correctly , was set at full load by another tech) .. They always came to me because I was the go-to-guy to get things fixed. But this was just a simple tire pressure adjustment, and I was sick of them... I had 4 grown men standing over me as I was setting the tire pressures, the customer said something smart-*** , and returned the favor..I got called in on the Corporate Carpet for my attitude. I didn't apologize, I told them how I felt about 4 grown men standing over me while I adjusted tire pressures for nothing and then get a smart-*** comment...lol..The "higher-ups" understood...... https://www.matcotools.com/catalog/p...ATOR-BURGUNDY/

So your Porsche customers were so "special" they couldn't even adjust their own tire pressures! I always wondered where the "snobby Porsche owner" mystic came from...now I know. Makes me want to buy a Smart Car. No not really.😜

Exactly !! It was very prevalent around the "Porsche Store" , but not so much in the "996 Community" .. .

Okay, I've solved all of our problems! Enough of these cheap $300 pressure gauges. One can get a 0-60psi gauge with 0.001psi resolution and NIST traceable calibration to +/-0.05% accuracy for only $1,218.17 !! https://www.mcmaster.com/3584K31/ Of course that's just the gauge, so lets round to $1,300 for the hose and valve. Who's first?

Dayum !! Better include a "rubber shock collar" also !! I'd hate to drop that one on the shop floor !!!
