How do you sure that this Tire Minder is accurate? You need to compare with a more sophisticated one.(Your Accuguage might not be accurate)

My accugauge appears to be accurate. I'm comparing to all other gauges I see, and the accugauge is supposed to be a sophisticated and accurate gauge. It got good reviews by those who test gauges (and posted in this forum). People need to chill out on this accuracy thing. If the gauge is out 10% (5% would be what I would expect with an electronic gauge) that is 3 PSI in 30 PSI. My tire pressure varies that much just from the heat of the sun. The electronic gauges could be out about 5% - I say this as this is "standard engineering accuracy". That would be 1.5 PSI in 30. That's pretty accurate. The rod type mechanical gauges can be out a lot more that that, because even a speck of dirt on the slider can stop it short of the true reading. I had one that got bent in my pocket! Imagine how inaccurate it was. Also the electronic gauges are more likely to be out the same over the full scale of pressures - for example 1 PSI high or low at any reasonable pressure it is designed to measure. The same cannot be said of mechanical gauges. The fact that the accugauge reads the same as the Tire Minder kind of gives confidence they are both close. That is, the chance they are both out the same amount is lower than the chance they are both accurate.
As long as you use the same gauge on the same vehicle and monitor the tire performance, you can adjust for gauge accuracy. eg - if you see the outside of the tread wearing faster than the centre (even on each side), then you are probably underinflating.
And my final word - What makes you think the vehicle/tire manufacturers pressure recommendations are the best for your use? We've already seen one case where there are questions to be raised!

I have the same Brookstone tire gauge, and it is almost as old. I am 99-44/100% sure that it is a rebranded G.H. Meiser Accu-Gage H60X (with the rubber guard). See link title
Brookstone still carries a similar model, also almost certainly a Meiser Accu-Gage: link title That one lacks the hose, but partially makes up for it by having a swivel chuck instead of the straight chuck of our model.

Nextech is just a Circuit City house brand. As noted elsewhere on this thread, Accutire is the brand of the Virginia importer of a Chinese line of tire gauges. Chances are the one you see at Circuit City with Circuit City's house brand is identical. Similarly, Monkey Grip is a line of Chinese-made tire gauges you can buy at many auto parts shops, but go to an Ace hardware store, and you will find identical tire gauges there under the Ace brand: the two are identical except for the printing on the cardboard the bubble plastic is attached to.

Personally, I think digital gauges are more hype. I have a digital (highly rated). And I have a pencil gauge from the emergency kit of a '91 Taurus. They consistently read within a pound of each other.
I like the pencil gauge better actually. It fits better over the valve and takes an instant reading. I can do two tires in the time it takes the digital to do one. Of course, it does not have a techie digital display

it's been a long time since anybody posted a gauge comment so i will share with you the truth about the gauge. accuracy of the gauge is secondary based on calibration variances. the real issue is that you own one and use it once a week.

I have a small digital gauge, says Tire Minder on it. Who makes this unit, how does it work?
