The cheapo digital guage was fond to be more accurate than any

of the analog gauges.

Since then I have been using an accutire made in taiwan special

that I bought at Menards for $5.

If you really want a good gauge, then buy a decent gauge with a good hose setup and buy a certified gauge from MSC or Mcmaster Carr. They have them certified to .5%. A good option is one certifed to 2% or so. then, just move the hose over to your new gauge.

I use Longacre, personally.

In the July 2001 issue, european car tested 14 tire pressure gauges, a sample representing almost the whole spectrum of what an enthusiast might buy, be handed at a show, borrow at the track or find rolling around in the glovebox of his idiot cousin's Fairlane. The most expensive gauge tested was $69.95. We didn't like it as well as a $19.95 Accutire digital gauge from Performance Products, which had a resolution of 0.5 psi and was one of only three to track our ANSI Grade 1A master gauge perfectly from 5 psi to 45 psi. We were aware of more expensive gauges, but the next step up in function, at least that we found in our search, was in the neighborhood of $250. It read to 0.1 psi, had built-in memory functions and would probably be great for people racing used Porsche Cup cars. For the rest of us, it was irrelevant.

It's important to note that a pressure gauge's stated accuracy is given in percent of full scale, and usually is represented by three numbers, i.e., 3-2-3%, and may even be called out as "plus/minus" which doubles the value.

These three numbers represent the accuracy limits at the low, mid, and upper range of scale, as a percentage of the full scale.

This means a 0-100 psi gauge that's rated at 2%, when used to measure my hot pressures on the race tires (~ 46 psi) could show me anywhere from 44 to 48 psi and be within the stated accuracy.

You need access to a calibration source to monitor the gauge's actual performance, they can drift on there own.

Or think what happens when the gauge gets dropped on the concrete floor !

I'm still a novice at this, but I adjust the tire pressure for a 2.5 lb differential front-to-back, and then measure the outside tire so that it heats up to the range suggested by the manuf (38-42 hot for RA-1's). I then adjust the other tires by the same amount. I really don't care about the absolute accuracy as long as the differential between the tires is correct.

Am I missing something?
