Looking for a good digital tire pressure gauge

[Aaron]

Looking for a good quality digital tire pressure gauge. Possibly something I can order online. WalMart didn't have anything I was interested in. I did a search on the forums and couldn't come up with anything significant.

Thanks

I own one of these and it's great. Accurate (shows to one decimal) and provides a very good seal to the tire valve. You can program your desired settings for both the front and back tires. I bought mine a few month ago for $9.99 (when regular price was $35). I see they dropped their regular price to $20.

We picked up a good one at Sears. Wasn't that pricey, and works very well.

I have the analogue version found here, and am extremely pleased with it, and I am sure the digital version is also high-quality. It's a real boon to be able to add air without having to remove the gauge, and get an instant readout after the filling ends.

While I admire the more-expensive tire gauges, a basic $10 digital served me very well since 2001. I suggest considering these, if only because it could get more people to have (and use!) tire gauges. Very important.

Peter Blackford in the yahoo toyota Prius group recently reiterated his offer to calibrate pressure gauges for any Prius owners, for the cost of return postage. He is in s. Florida, and hope that he does not mind me mentioning his offer here!

I don't know what he uses as a standard, but my cheapo gauge tested within a psi way back when. Not all will test that well, but if you know the calibration, that's plenty good enough.

I really like my Tire Minder TMG-340 from Pep Boys. Cost $15:

In another tire pressure gauge thread, 1fixitman had some interesting things to say about gauges, mainly that the accuracy of the digital gauges he tested on a calibrator tended to fluctuate with the temperature of the gauge:

I highly recommend you purchase an analog dial with a minimum of 2 PSI increments on the round face. You can find ones with 1 PSI increments. An analog guage has a needle for indication. Get one that has a good piece of rubber protecting the dial portion of the guage. I purchsaed one from PEP Boys that reads out in 2 PSI increments and has the little button that helps you release pressure while you are measuring pressure instead of manipulating the needle valve in the tire with a foreign object to release pressure. The max pressure is 160 PSI for the one I have and I paid $15. You can also look at any of the local automotive stores like: Advance, O'Rieleys, Napa, Auto Zone. I found a better selection at Pep Boys. One other option is to find a truck stop.....but you will pay more at the truck stop than any of the above listed stores. I actually tested all of the different types of tire pressure guages while cool and while heated on a Ruska pressure calibrator at my work. The most accurate under all circumstances was the analog needle style with round guage. I am a Service technician at a Bridgestone/Firestone OEM tire manufacturing facility in South Carolina. Hope all of this makes sense and helps you get an accurate guage. If you pay for a cheap tire pressure checking device then you will get a cheap device. Make a small investment. I keep mine in the driver's side door panel so it is always in the car.

I would add to his comments that generally it's better to get a gauge with the lowest maximum pressure that would accomodate the highest pressures you will be measuring. E.g., if you will be using the gauge to only measure car tire pressure, then all other things being equal, a gauge that measures between 0-60 psi will be more accurate than one that measures between 0-160 psi.

Personally, I use the Accu-Gage brand that he mentioned and that Birdsquared also mentioned and linked above. I use one of Accu-Gage's "Professional Series" analogue models that measures 0-60 psi in 1 pound increments, with a release valve and swivel chuck (cost ~ $15).

Accutire, $7 at Amazon. In a few comparisons with a gas station air pump gauge they always agreed.

I got a cheapie from Advance Auto Parts, formerly Discount Auto Parts, a year ago, runs on lr44 batteries. blue backlight on the lcd and illumination, works great, probably costed 10 usd.
