While at a friends house over the weekend - he commented - your front
tires look low - nah said I - just checked them - got out my ancient
gauge - stick with plastic bit that is pushed out the end- 29# it sez -
yep low it is I said. He whipped out a digital gauge and said check it
with this - 24# it sez.

Being off 5# is way too much. I suppose the round dial gauges are
better but this thing seems to be very accurate - bought one and got
the identical readings 31.5 as on my friends digital gauge. This one
is called Monkey Grip - has a permanent but replaceable batteries and
is less than $10.

Not affiliated with any auto parts products at all but have ruined some
tires by running them under inflated.

I have a Accutire MS-4020 digital tire gauge (approx. $15 to $20), and
two Accu-Gage analog dial units - an RS60X and a RH60X ($13 and $16
respectively). Both the Accu-Gage gauges correlate exactly on measured
pressure. However, both read exactly 2 pounds lower than the Accutire
digital gauge. So, which one is correct - that's a good question. Just
because a gauge's readout is digital, doesn't mean that the actual
pressure "measuring" is more correct. I wish I had a "reference
standard" to compare these against.

Consumer Reports did a comparison about 8 years ago, and found that pen
type gauges can be accurate but frequently aren't unless you buy the
"right" brand. I did, but now wish I'd bought a handful. No doubt the
AutoZone gauge they recommended has gone through a few changes. (There
were actually two AutoZones tested -- one model was excellent, the
other sucked.)

The dial types are very accurate, typically. Until the first time it
gets dropped. Then all bets are off.

If you're rough with gauges, or have some extra bucks to spend, I'd
wager on the piezo electronics to be pretty accurate in general.
