Technical Need a source for accurate tire pressure gauge, thanks.

Just found out this morning that my tire pressure gauge that I thought was accurate may be as much as 5 lbs. off at 35 lbs!! Seems like it loses accuracy incrementally as pressures increase. Checked with a (deemed accurate) tire store gauge at 35 my "trusted" gauge measures 41!!!...I don't mind spending $30-$40 for a good one. Really don't want to spend $100 for sure. Help me out guys, I have know idea where to look. Mine is a round analog gauge that came from Brookstone quite a few years ago. I really don't trust the old style pencil ones. What are your recommendations?......Thanks a bunch, Don.

 

The Moroso round gauge with a hose is made in Brazil now? Anyways, that's what we use when go racing, but our racing is purely amateur.

Thanks, Jim.

 

Go find a snap on truck and buy the Blue Point tire pressure guage, or order it from snap on. Ive been using basically this same one for 20 years. Its always dead on.

be sure to keep an eye on your blood pressure too

 

Thanks, Jason. I was just nearby a Snap-On truck this morning,but didn't get too close. Getting too close can be costly!

 

Don, I have one of these, it's similar to the Moroso.

 

its not cheap, but if you use it forever, its worth it. 68 bucks on the snap on website, but I believe its about 45 on the truck.

 

I use a snapon, blue point gage with hose. I also have a moroso 0 to 20 lbs gage.

 

Got the same one. Works great and has a glow in the dark feature if that matters at all.

 

.............I can live with $45.

 

if you get one, let us know where it was made....I hope it's as good as the 20 year old variety!

 

I made my own. I took the guage from a New Way air valve that supplies the air to a New Way tag Axle on a semi truck. I attached it to one of those long stem air chucks used for inflating the duals on trucks. been using it for decades. ive got another made the same way with a different guage. on occasion I check with both gauges they always read the exact same pressure.

 

Actually I have three of those homebrew tire gauges. two stay in the shop. the other stays in my wrecker. I always carried one guage a air hose and tire plugs when I drove semi trucks. The New Way guage can be recalibrated ive never needed to adjust it.been using it for decades. .

 

Check out Longacre and Intercomp. Both are good quality gauges and I have a low pressure and a high pressure I've used for years.

Do any of these gauges stay on the pressure until released?

 

The Blue Point Guage that I have and put the link up for does. It has a release valve on the side that you push to bring the gauge back to zero.

 

Thanks, that’s getting up there at $99 Kiwi $ plus shipping.

 

We use the Blue Point one on our aircraft and have only had to replace a couple over the years due to calibration issues. We have 100+ of the gauges in use worldwide.

 

We use a Longacre with our race car tires...

 

Came to say this.
Have used a 4.5" face gauge for a few years, handy, very easy to read(especially at night) and seems to have stayed accurate.
Smaller 2" units are ~$30, the 4.5" was over a C-note, dunno what it would cost now.

 

.......I really like that particular feature.

 

I use a Milton 572D. I really like it as it is easy to see (digital) and has a bleed button. About $100 from Summit.

Damn- I remember when $100 was a pretty tall car payment. I think it was when I had a $222 house payment in 1973.

 

anyone pays $100 for a tire guage has more money or credit than brains.

 

There is an International Standards for Accuracy (ANSI standard)that the best gauges are calibrated to.
The calibration insures the gauge reads within .1%(or less) accuracy when calibrated to the ANSI B40.1 accuracy standard.
So if you follow that guide line-you will get a pressure gauge with a measured level of accuracy.

 

I have a Blue Point digital one at work with the flexible hose and dual foot on it for dual wheels. I bought it when TPMS became mandatory on light duty stuff and on cars. I’ve had it 8-10 years, don’t remember what it cost. Doesn’t matter, it keeps comebacks down because of TPMS lights on the dash illuminating.

I have a 0-100 psi gauge I took off of an old actylene regulator screwed into a long stem inflator. I checked it against my buddy's Longacre gauge and found it 1 psi low at 36 psi. I'm cheap.

 

I buy inexpensive digital tire pressure gauges from Amazon and have one in the glovebox of every vehicle I drive. I have tested them against other shop gauges I have and find them quite accurate. This is the brand I have used for at least a decade and occasionally buy a few more for family and/or friends ‘gifts’

Both national manufacturers Schrader and Dill make what are called master gauges, used to check or calibrate other gauges. They look like the Snap On one shown. They also make a calibratable stem type gauge. Any gauge that has been dropped or thrown around is likely to be off.

 

So how did I do?
