Default Accutire Pressure Gauge. Where to buy?

I'm looking to get an Accutire Deluxe tyre pressure gauge. Anyone know if it can be bought locally? I looked on Canadiantire.com but they carried a line of rubbish gauges.

It looks like this.

Danke!

go check Canadian Tire, they carry accutire pressure gauge, but I dont know whether they have the one you'r looking for or not. I just got a cheaper version LOL

hmm in general, mechanical type meters are more reliable. Dunno about tire gauges tho. I saw some digital ones at Lordco I think.

eg. mercury thermometers are much better than digital ones.

I bought that exact one at a Canadian Tire a little over one year ago.

I read a review on tire guages once. Mechanical ones are more precise, but digital ones are more robust. Drop a mechanical one once and it may be out by a couple PSI.

yup... the digital ones available to the average consumer aren't capable of re-calibration, just get a mechanical one, it's not like they're hard to use..

u can get those at crappy tires for sure
just got one for myself over christmas break, it's was on sale and super cheap~

i think for average users the digital one should be sufficient, digital read out are a lot easier to read IMHO (than those tire gauge stick), and it's pretty light too...
the only down side is that the mouth (wut's the correct term??) where u connect the gauge to the air steam on the tires is kinda shallow so harder to use...but it just need some getting used to and some practice..nothing major...

Thanks, guys.

Would you recommend getting two? An accutire digital to store at home (where it won't ever be dropped) and a second mechanical one to use and to recalibrate often, using the digital one?

How do the re-calibrations work?

Yeah, that's about right.

AWD - are the mechanical ones more precise or more accurate?

I am also skeptical about a silly little piezo pressure transducer being able to hold its calibration over a long time, but on the other hand, that digital precision makes me feel safe. I've been using one of those accutire keychain models for a couple years now ... it's probably all out.

you dont recalibrate the mechanical ones.. thats the thing, you dont need to. they'd have to be really messed up to give inaccurate readings (and they're cheaper too). But hey if you dont think you'll ever drop it or anything, by all means, get the digital one, they're more convenient.

Do you actually recalibrate your mechanical tire gauge??

Personally, if the tire gauge drifts I'd find it easier to use a digital one with a known conversion table, than an analog one with the same setup...

no i was referring to digital (for calibration).. since I know they tend to be easier to 'mess up'.. on my last physics labs we have to calibrate the computer probes with (in the case of checking temperature) a thermometer. They give us digital ones since people would always drop the mercury ones and break them.. however the first two digital ones I used to get the temperature of iced water (approx 0 degrees celcius) gave negative readings which is ridiculus.. third digital thermometer I used seemed to give an accurate reading of 0.4 degrees.. all I'm saying is that mechanical ones tend to stay good and true while digital ones are easy to use and all, they tend to be more 'fragile'..

Umm okay, but according to AWD and the study below, the digital ones are less easy to mess up by dropping them... it's the analog ones that seem to be more fragile. And it kind of makes sense, too, that the analog ones would be theoretically more sensitive to stuff like temperature and the age of whatever lubricant is inside...

http://www1.agric.gov.ab.ca/$department/deptdocs.nsf/all/eng5242?OpenDocument&Click=

Cliff notes: according to that study, the Accutire gauge was kind of middle-of-the-pack in terms of accuracy and durability. The best gauge measured was a $6.00 Superex pencil-type gauge. The dial gauges weren't as accurate.

I'd like to see a study where they compared drift in those tire gauges over a number of years. Maybe we should all get together and do a little survey on some known pressure using whatever gauges we have on hand, taking into account their age and treatment... mini-meet anyone? Anybody have access to a lab-quality calibrated pressure gauge?

I have access to the lab pressure gauge but it requires a computer, the software, and some sort of attachment to make it connect with the tire air valve so I don't think that'll work. But I'm always up for mini meets regardless of reason . By the way I use a typical cheap pencil-type gauge so its easy and cheap to replace (mine was 5 bucks) as well as accurate. I assume those digital ones can cost around 30 bucks? (random guess)

I have a nice polished steel stick type myself, but I am seeking a digital so that I can have the precision of knowing that I'm not just reading the stick at a bad angle.

Well, digital ones only read to .5 PSI. Granted, an analog one may not be accurate within .5 PSI but at least you can get all your tires exactly the same.

It really depends on what you use the guage for. For example, for autox it's nice to have a large analog dial guage with hose and a valve to bleed off air. That way you can quickly and easily adjust your tire pressures to be exactly the same between runs. Chances are in that case you're not as worried about accurate readings as you are in consistent and precise readings. To be honest, even there .5 PSI difference probably isn't noticeable.

Also, temperature has a large effect on tire pressure. There are so many variables that it's probably not that important for your guage to be incredibly accurate, but you don't want it to be out by several PSI either.

All in all, if you're that concerned about tire pressure, you probably have done some experimentation to determine your on preferance and as long as you always use the same guage you'll have the settings you like.
