I have 3 gauges.

This Accu-Gauge reads 34








This Accu-gauge reads 44









And this Accu Gauge reads 40






I had a Campbell Hausfeld pencil type, and it was around 46.


I've been playing around with these for over 6 months.
I use the one in the last picture, coz it was more $$$ :shock:
These were all bought this year. Any ideas ? Digital maybe?



:twisted:

You have an issue. I have to suspect the first gage is bad. 10 PSI is just too much difference to ignor. Nevertheless, you don't have enough data to draw a statistical conclusion. The three other gages may be showing normal variation based on a 43lb mean.

6 PSI is enough of a difference to be concerned.

I have two gages; a pencil type attached to the compressor (Harbor Freight el cheepo) and an Accu-Gage digital (about $13 from Amazon). They read about 2 PSI different from each other with the digital being the most repeatable.

Digital gages are not more accurate, but they have no moving parts and are infinately more repeatable. Give me repeatable over accurate any day. That way you will at least know your readings are consistant and you will always be able to set your tires to the same pressure. The variation in the mechanical gages makes them less repeatable so, you never are really sure what your reading is.

I know this was vague, but I hope it helps a little.

I use gauge #3. It matches the reading from my Smartire.

If you check a dozen tire gauges against one another, you will most likely get as many different readings. I have found the dial type to be more consistant than the traditional pocket gauges.
No opinion on digital. I havn't used any of them.

I have used both and I prefer digital. Much more accurate.

Sorry to hijack-but I cant seem to find the accuguage website
My accu gauge crapped out after a month
and I heard they are guaranteed for life

Go digital, I did, logically speaking: no mechanical parts equals less chance for inaccuracy. T. 8)

Rastoff has it nailed. Replication is more important than nominal accuracy, but you gatta have accuracy within reason. Fuse has a very valid point; and in most cased the answer is we really do not know since calibration devices are not common. BUT, the piezio electric chips in the digital tyupes are very consistent and inexpensive to produce, thus the manufacturer only has to get a lrge consistent batch of chips (crystals) and spend his money far less often on calibration runs per given lot - plus they are stable over time. I use inexpensive digitals.

Guage number 1 was the one I threw in the garbage. It was 10 pounds OVER.

Again, I have to ask. How do you know? I know that they read to the pound plus 10ths but how can we know if they are really accurate.

I myself like the one pictured number 3. Not so much because of it's accuracy, I can't tell you how accurate it is. But I like the button on it so I can inflate the tire then push the button to bring the pressure down to exactly what I want. I always use the same one so I have my pressure at a consistant level.

I have guage #3. I use it on my wing like you because it costs most.
I checked it to a pencil guage I've had for years, and it was very close. I also have one similar to #1 that was also very close.

Maybe I got lucky???

Just curious as to what race car mechanics use. In Nascar they worry over 1/4 pound increments or even finer for all I know.

When the outcome means lots of money they use the best.

disclaimer- not a Nascar fan just know they deal with this stuff constantly.

ditto there is no proof that digital is more accurate than analog

I'm not sure of what they use but I can guarentee that they have them calibrated all the time. That is really the only way to make sure that they are accurate. I myself just don't know how to get mine calibrated, and even if I did I'm honestly to lazy to do so. :)

I have a digital and the #3. The digital and the Accu-gauge read exactly the same. I carry the Accu-gauge with me because of its ease of use and its ability to fill and expel air from the gauge side.

I bought my digital gauge at Wally World for about $10.00. From time to time I compare it with my pencil type (like # 2) and they read about the same.

I have been looking for something like # 3 but have not found one yet. Anyone know where I can purchase one like # 3?

BTW, do you put air in your tires with the bike on the center stand, or on the side stand, or maybe when on a jack? :?
