Tire pressure gauge

[Morris Minor]

For my birthday, my dad sent me one of these:-


It works well & is easy to use but, honestly, I'm not 100% confident in its accuracy (nor any of the others I own). It reads 1lb/psi higher than my conventional mechanical Accugage gauge which, in turn, is different from a couple of pen gauges I have. I'd like to be able to take it (& the others) somewhere to make sure it's calibrated correctly - so far I have not found a resource available for this.

Stick gauges are the least accurate.  Your accugage is likely pretty accurate, so if anything i'd take that 1psi discrepancy with a grain of salt.  1psi doesn't really matter that much anyway, IMO.

Personally I have a mechanical Accugage and a digital Snap-On, and I compare them regularly. They are pretty much in sync.

One or two PSI isn't a big deal unless you're traveling 150mph or more around a track with 30 other people.

I've had customers check their tire pressures with a Walmart special before leaving the parking lot and complain that my tech got their tire pressures off by a couple of pounds.  We would have to take the digital gauge out to their car to prove that the tech was correct. 

I wish I knew who made the tire pressure gauge that Ford sent to dealers.  It was simple and accurate.  We received it during the Explorer/Firestone fiasco.

My service manager was disappointed to find it didn't work one day.  He was trying to find a name on it so he could order another.  I said that it might just need batteries....he looked at me and said, "you think it has batteries?"  Me, "you think it lights up from you holding it?"

I need a new one.  I had a really good one at some point, but I don't know where it went.  Maybe it's in my brother's car....

i have a craftsman digital that someone bought for me for x-mas... really its not any more handy then my previous $5 dial gauge i use to use

Too bad the best gauge you could buy, a Drager,  is no longer being made.

I use one of these:

That looks a lot like an accu-gage.

I like these:



They have an air bleed on them and they're easy to read. They come in a 60 psi version, by the way.

I have an accugage, but what do you guys use to read tire temps?

My dad has two of those.

I'd recommend an IR thermometer.  I don't have one personally, because I don't need to measure tire temps...

[Byteme]

Everyone needs an IR thermometer.     

You'll never be aware of how many things you wanted to know the temperature of until you get one.

What's the temp of the dog?  The fish?  The outside of the thermometer?  Your dashboard?  Taht concrete drive?  That TV screen?  You'll spend the first week checking the temp of everything you can think of.

lol, good point...

I've just realized I urgently need one of these.

I have 4 onboard infrared cameras to scan tire temps, and I have sensors on the control arms/chassis that compare body to wheel motions and back calculate tire pressure (and suspension bushing compliance). Pretty accurate, down to about 0.00005%. Decent I guess.

I don't like poking holes in my tires though.. it makes them look ugly

What...no on-board tire heaters to bring the tires to operating temps before taking to the roadways?

wut

wat duz dat ting do?

this works for me

So, what exactly is the most accurate type of gauge?  And how are they calibrated to make sure they're accurate?

[JWC]

I couldn't tell you which is really the most accurate.  I checked mine against each other.  I had probably six tire pressure gauges.  I checked one tire with each and whichever was more than two pounds off, I tossed.   The cheap Walmart one passed.  Since that check, I'm down to three.

Yeah, that's kinda how I do it too.

I actually compared my little cheapo pokey-dial gauge against an expensive brass-shit-with-a-hose gauge at an autocross and they read out the exact same.
