I will explain my situation a little later, but am also curious what you guys think about accuracy.

 

Number 1, round dial BUT....I still went ahead and picked up a $20 electronic that holds the reading in place till I clear it. I have tried it against all 5 of my other gauges and it was dead on. One of the pen type was 4 pounds low.

 

numer 1.

 

The reason I was so "moved" to seek different opinions is that I now have in my possession 3 gauges. One Accu Gage that I procured at Sears this afternoon while having an alignment done on my wifes truck, and 2 slime stick gauges that was purchased at different times at my nearest Wally World. One of the slime gauges is 0-50 and the other 10-120. A short while after I had new tires put on truck and car I decided it was time for a new gauge as the 6 year old Bridgestone one I procured from my dad was of the heavy duty application and I suspected that it may not be within accurate spec anymore. I bought a slime stick gauge from my trusted China Mart and compared against my Bridgestone and the gauge at the tire shop. I do not remember that reading of tire shop gauge and slime one but the difference was negligible but the Bridgestone one was 5-6 PSI off so in the trash it went. A few days later I bought another slime 0-50 gauge and compared to previously bought slime gauge and the readings were a spot on. The universe moved in perfect harmony for a blissful while as I drove in confidence that my tires would not suffer a premature tread separation because the pressure is as I like it 5 PSI over manufacture spec. What threw a monkey wrench in my bliss was the day I decided to check the pressure on my spares, which incidentally, were both at the 15 PSI mark. The spare in the truck now inflated to the max. 44 PSI, time to inflate the donut that belongs in the tuna can. I inflate to the recommended 60 PSI and check and out pops the plunger of my 50 PSI slime pencil gauge. Not to worry friends, I hot foot on down to Wallys and purchase another slime gauge, this one 20-120 PSI and am satisfied as I have received 4 valve stem caps as a bonus for buying a gauge in the package instead of out of a pencil cup on the shelf. I compare this gauge to my other 0-50 slime gauge and find that this one is more difficult to read as it nows marks in 2 PSI instead of every PSI, I also find that this one reads 2 PSI lower than my 0-50 slime gauge. I inflate my Sentra tires to 36 PSI for the sake of reading the gauge. I read a thread on another forum about pressure gauges possibly not being accurate out of the box and kind of brushed it off as I know this information and besides my gauges are not that far off, at least not for my **** tendencies. IAC, I am at Sears today speaking with the tech after my alignment is done and he mentions that my tire pressure was 40 PSI but he aired them down to factory spec for me which is 35 PSI. I nearly had a coronary. Not only because I WANT my tires at 40 PSI, but the tires are HOT and he dosent know what pressure was really in there to start, and besides the nerve of him to think that I want my tires at factory spec. He is confident that he has 35 PSI in them according to HIS pencil gauge so I decide that this may not be totally bad and I am tired of pencil gauges anyhow so before I check out I grab an Accu Gage like the first one I posted. I return home and compare it to my 0-50 gauge that stays in the truck and find that 0-50 slime gauge says 40 PSI (tires are still hot) and Accu says 36 PSI. I stroll the 3 feet to my tuna can and open the truck and find my 20-120 slime gauge and compare the three on a car tire. The slime 0-50 says 37 PSI, the slime 20-120 says 36 PSI and the Accu says 34 PSI. Now that I have 3 DIFFERENT readings I convinced that the CIA is tapping my phone calls and frying my brain with microwaves sent from space. Which one should I trust? For the time being I have set all three of them in the trunk of my car and will try to test them again in the morning when truck hasnt been drivin and car hasnt set in sun all day. Sorry for the long post but it is all relevant to my sanity ATM. Thanks.

 

holly long post man.

i dont think it matters ive used both. I perferr my dial like the first you posted. But i have countless amounts of those pencil types.

im intrested in reading your test results tomorrow.

As **** as it seems i find it amusing.

 

Uhm...


Can we say OCD?











On another note. Let me know which one is correct and more accurate as I need another one. The only one I have is the one attached to my compressor hose

 

lol

I brought myself around to reading it... usually I find that long posts are rather interesting... That sounds really weird. I really never gave it much thought. I have used them both. But I prefer the dial. I can say that the pencil ones will definitely get different readings... I have used the same pencil gauge on the same tire several times and gotten different readings each time. Normally on the first it'll be something like 33, then 36, then 35, and then 35 again... and Im satisfied when I see a repeat... The pencil ones stick sometimes and don't extend out all the way sometimes, which you probly already knew, but that's why I don't like them. Let us know what you find in the morning, this is rather interesting.

 

haha...wingman likes "long posts"

 

I just checked everything out with cold tires. I also just reread my post from last night, man was I short circuiting, thanks Coors Light. Based on the fact that I am sure I had 40 PSI in the tires on the truck before the alignment in which the tech let out 5 PSI and according to his gauge is supposed to now have 35 PSI in them, the Accu dial gauge says 36 PSI and the two stick gauges say 39 PSI. I adjusted the pressure in the cars tires before I left work after they had been sitting 11 hours overnight and they had 34 PSI in them, now stick gauges (same one that told me 34 PSI) now say 37 PSI and the dial gauge says 33 PSI, so I will throw the two stick gauges away and take the dial gauge for gospel until I buy a digital gauge in the next week or so.

 

You really take air pressure seriously, don't you? Ive, never purchased a gauge. Have a coulpe of stick gauges that I inherited from my Dad about 50 years ago and a dial type that was a gift.

 

I'm thinking with that much worry over air gauges you might want to be more concerned with your blood pressure instead of your air pressure?

 

We wont even get started over BP cuffs, it is more trouble to get an accurate reading off of one of them than the cheapest stick gauge. I am going to throw out the stick gauges and keep the dial and also buy a digital. It is the popular belief among professionals that the digital gauges will be the most accurate.

 

I've always got more consistant readings with the dial guage. I have a digital one I use most of the time.

 

I use a campbell hausfeld digital. That way I can get down too 1/100's of pressure.

Seriously, though, digital.
