Let's talk about devices that are not obviously in need of repair or
adjustment.
Not even you could believe that 15 minutes per day is the maximum
accuracy that Rolex is capable of.

The term is "sod all", not "sod".
Even when presented with the term in print, you can't get it right.
It's no wonder your posts about the relative efficacy of digital vs
analog tire pressure gauges are such crap.

My theory is you get what you pay for. If you are willing to spend a
whole lot of money, you can get a good digital OR a good analog gauge.

I think the *secret* is to get your *stuff* where the mechanics get
their stuff, like from Snap On, or such, but that truck is hardly ever
in my neighborhood.

I run my 30 lb tires at 35 BTW. Much better handling, less wear and
tear on the side tread when taking corners, the power steering is much
more responsive.

From time to time I check the tread depths -across the tire- with a
depth gauge on my digital vernier calipers. I can see if I have to
adjust the pressure up or down from there. Maybe 35 is OK for now,
but if I am getting excessive wear from the center treads, I know to
back it down to 33.

I know one thing for sure, the 30 suggest inflation pressure is for
ride comfort, not longevity of the tires.

Actually I agree with you. I think an accuracy of +/- 1.5
psi is probably sufficient for most drivers. A precision of
0.5 psi would be nice, since I believe it is more important
to get the left and right side tires to the same pressure
that to get them to the exact manufacturer's recommended
pressure. BTW, I think the change in atmospheric pressure
for a 1000 feet is only about 0.5 psi.

Actually, your $20 digital watch is more accurate than any mechanical watch.

I take the analog gauge any day. No batteries to mess with. Easy to use.
Cheap to buy.

You should have bought a Tag Heuer, then you could have found batteries
for it. I know Radio Shack has batteries that will fit a Tag Heuer.

These will be the most accurate watches, but all the ones I have seen are
fugly.

For crying out loud - go buy a digital tire guage then an analog tire guage
and check
the calibration of the analog guage against the digital one - and mark any
difference
on the analog guage. Then both your guages will be inaccurate by the same
amount!

Because having tires that are inflated at different pressures can
cause a car to spin when stopping on ice.

Yes. Maybe you should respect those who have it a little more (which
does not imply that you do not have it.)

So are you a Glickman sock puppet claiming that there are no
bourdon tube analog tire pressure guages? If so, you too are
not only ignorant but too lazy to check your facts.

Yup. As do most watch stores. The hard part is finding a store that
has the little watertight gasket on the back, as only Swisswave tends
to carry them.

The Junghans models aren't too bad looking, I just happen to prefer
the looks of the Tag Heuer chronometers with the sport band.

I have a real Tag Heuer and a fake Tag Heuer with the stereotypical
cap-tuned HongKong innards. No surprise, but the fake one is just a
tad more accurate, and the real one gets adjusted by Swisswave every
time the battery needs changing.

If there are quality 'fakes' out there, why pay for the real one?
Plus, why the heck do people pay for such expensive watches?

Just asking.....
