I'm pretty sure they are supposed to be "reset"--not trivial, but takes
less than 5 minutes after you spend 10 minutes reading the directions in
your owners manual.

Hi,
IMO, that's a matter of personal opinion. Our cars came with it on both
summer tires and winter tires which has Nitrogen gas inflated. I like
it as a safety feature.

Not on my vehicle (the 5 minutes).

It's more about safety than anything, and helped keep the SUV markets
alive when roll overs were happening with them. Next time ur on the
highway and a big arse SUV is running along side or coming at you, it
would be best if it had enough air in it's tires.

something like a Toyota SUV pulled up next to me and the damned thing
was bigger than my van. Geeez! o_O

Not quite.

Ford was seeking a softer ride for the Explorer, so they specified a lower
pressure than Firestone spec'ed for that tire. The problem was that by
spec'ing such a low pressure they removed the safety factor, meaning that
only a little pressure could be lost before the tire was in danger of
overheating. Then one day an Explorer in Texas during a heat wave had a
low-pressure situation, a tire blew, the vehicle rolled and somebody died.
I can't quite remember now, but I believe the deceased was beltless.

Ford tried to blame Firestone, which did their own investigation,
discovered the non-authorized pressure setting, and disclaimed
responsibility. Then the lawyers and activists got involved and we now have
mandated TPMS. Never mind that Texas-type incidents are vanishingly rare
("if it saves just one life!"; "it's for the Children!").

I had a Volvo in which one of the sensors went bad. I'd get the warning on very hot days, temps over 90 F. The first time it went on, I pulled over and checked the tires; all were OK. After a few times, I just started ignoring it. I routinely check the tire pressure on both cars and the truck every month.

That's all complete horse pukey. The explorers problems were ENTIRELY
due to defective firestone tires, not low tire pressure. The tires
were literally crap from the day they were made, they were not even
balanceable, I own a 92 explorer and have since it was new. I threw
out the firestones with half the tread still on them because they were
NOT balanceable and literally would shake the truck like it was on a
log road. A new set of Michelins and the truck rode like it was on
glass. Ford also sold the same vehicle with Goodyear tires on it.
They had NONE of the alleged "low pressure" problems on the ones with
the Goodyear tires because it wasn't 'low pressure' that was the
problem, it was the crap firestone tires. I have seen so many
firestones blow out over the years that I will NEVER buy another
firestone, just not worth the risk.

It was ONE incident. I'm quite certain that there were many more other
Firestone-equipped Explorers on the road that day in Texas, and all those
other ones made it to where they were going without driving straight into
the news..

Ford /did/ specify a lower pressure than Firestone recommended but, it
appears only ONE Explorer suffered for it.

If it were up to me, I'd prohibit any government worker from having the
power to mandate anything.

One of the things brought out in the lawsuits was the warranty claim
history for the tires and aside from whether a blowout might have
caused an accident (blowouts almost never do) the warranty history
clearly showed a VERY VERY LARGE difference in tire warranty claims
between the Firestone tires and the Goodyear tires. We had load range
E Firestones on one of our work vans and TWO of the four tires blew
out within 15,000 miles. These tires were scrupulously checked,
virtually daily, for tire pressure and were never run low and were way
over rated in terms of load capacity yet 50% of them failed. Yeah,
it's anecdotal but this has been a recurring story of Firestone tires.
Same thing happened on their original 500 series radials as well as
their 721 series radials.

Incidentally, 4x4 Explorers had lower fatality RATES then some

Over ONE incident. ONE is all it takes, these days. Never mind how many
millions of other identical actions occurred that year with no problems,
it's that ONE which counts.

Activists want the perfect world, and are quite willing to sacrifice you to

We see the same thing in the anti-gun hysteria. The media has people
so whipped into a frenzy it's beyond belief. I've talked to people
who will refuse to attend a meeting if guns are going to be TALKED
about and others who refuse to attend meetings if the organizers don't
institute a ban on guns. These same people are more likely to be
struck by lightening but they don't hide under their bed every time it
rains. American has turned into a nation of fools lead by fools and
it's heading down the crapper. People like to think we have some long
long history of "being right" in everything American but in terms of
world history the USA spans barely more then 2 centuries and it's not
hard to imagine there won't be much left of it by the time of its 300
year birthday. Things could change but I'm not optimistic.

Well, DOH!, no, but it's far less of an occurrence other than perhaps
after a flat repair or the like. Plus, in general most current
passenger tires are rated for 40 or so psi as max and they'll actually
run cooler (albeit harsher ride) at the higher pressures so it's pretty
unlikely to ever have one high enough to actually be a real concern...

Possible, sure, but not very likely particularly in comparison to
under-inflated which is both more likely from starting at low
recommended pressures with any leakage and that low pressure equates to
more sidewall flexure which is more heat which is the real culprit in
causing failures at speed. There's secondary contributor to
excessive/uneven treadwear of course.

The only warnings I have ever received were while on a road trip and
they were "tire pressure too high".

On a half-dozen or so GM and Chrysler vehicles I have/had that's never
happened -- the firmware seems to have sufficient leeway on high side to
account for warmup. I tend to run to the higher range of rated
pressures; 35-36 usually instead of the low 30's typical of the vehicle
column stickers. Whether that has any bearing or not I've no data to
refer to. I have had a time or two when did have a low warning the
second morning out -- why that's a pretty common possibility for us will
be seen from the next paragraph.

Since we're on several miles of gravel roads and there's always new junk
turned over every time they're graded, punctures are a way of life,
particularly on the passenger cars. Hence it's pretty common to get a
'low' indication the next time go get in the car from having acquired a
new slow leak...that is actually a useful feature particularly for the
wife to go by the tire shop when she gets to town if it's at, say, 20 or
so so it'll make the 5-mi or so trip...or even if lower to add some air
before she heads that way. So, overall, imo they're _a_good_thing_ (tm).

Then how come in NASCAR they start out with really low tire pressures at
the start of the race or after a pit stop to allow for the pressures to
build up?

There are two different ways to relearn your Tire Pressure Monitoring
System (TPMS). One is with a TPMS scan tool (this is the preferred
method) and the other is the manual method (pain in the "you-know what",
but requires no special tools or equipment).

To use the manual method, set the parking brake. Enter into TPMS RELEARN
using the Driver Information Center (DIC) controls. (SEE Owner's Manual)

When you have successfully entered TPMS RELEARN, the horn will chirp and
the left front turn signal will illuminate. Increase or decrease the
tire inflation pressure on the left front tire for 8 to 10 seconds. The
horn will "chirp", indicating that the left front tire pressure sensor
has been relearned and the turn signal at the right front will
illuminate. Repeat the process for the right front tire. The horn will
chirp and the right rear turn signal will illuminate indicating that the
right front tire has been relearned and now you must now repeat the
process at the right rear tire. Then you will have to repeat this a
fourth time at the left rear. When the left rear tire has been
relearned, the horn will sound a "double chirp" indicating that the
relearn process has successfully completed.

off the rim but that's just mashing a couple of buttons on the control
panel--just how depends on the vehicle, of course.

Snipped and hit send by mistake above......this is what I have to
do....and it's a PITA.

There are two different ways to relearn your Tire Pressure Monitoring
System (TPMS). One is with a TPMS scan tool (this is the preferred
method) and the other is the manual method (pain in the "you-know
what", but requires no special tools or equipment).

To use the manual method, set the parking brake. Enter into TPMS
RELEARN using the Driver Information Center (DIC) controls. (SEE
Owner's Manual)

When you have successfully entered TPMS RELEARN, the horn will chirp
and the left front turn signal will illuminate. Increase or decrease
the tire inflation pressure on the left front tire for 8 to 10
seconds. The horn will "chirp", indicating that the left front tire
pressure sensor has been relearned and the turn signal at the right
front will illuminate. Repeat the process for the right front tire.
The horn will chirp and the right rear turn signal will illuminate
indicating that the right front tire has been relearned and now you
must now repeat the process at the right rear tire. Then you will have
to repeat this a fourth time at the left rear. When the left rear tire
has been relearned, the horn will sound a "double chirp" indicating
that the relearn process has successfully completed.

Yep, that's how I did it! I had to read it a couple of times before I
believed it! LOL

And you need two people to do it.

Are you serious about this ?

What kind of vehicle ?

My Toyota only requires a simple press of a button.

I have seen where you may have to do something like that to reset or use
another of the door unlocks.

No, I've done it by myself on two different Buick's (6 years

What in the world vehicle is this on???? Some firmware engineer needs
firing over that one...

GM vehicles are simply manually set pressure w/ tire gauge to desired
and then hit a 'Reset' button on the monitor screen...there are very
slight differences in where the function's hid but if you've done one
you can figure out any other that I've seen w/ only a few tries...

The above is for a GM vehicle.

Where is this "every time" idea documented ??

Depending on which style of sensor is used, only the rubber valve stem
needs replaced with a repair/rebuild kit like this:

They're not meant to be money saving.

They're meant to satisfy an NHTSA safety regulation that all tires have
their pressures monitored by an on-board computer.

The idea is that you'll thus be less likely to have a blowout that might
cause the vehicle to crash and kill you. Not that that's particularly
likely anyway, but once activists and bureaucrats get a bee in their
bonnets, there's no stopping them.

Who told you that? It's wrong. The TMPS sensor should unscrew from the
valve stem, allowing it to be transferred to the new valve stem that will
come with the new tire.

I was under the impression the sensor was viewing a profile of the
tire. I could be wrong, but I don't think there is anything attached to
the valve stem!

All the sensor does is detect the absolute pressure inside the tire; it
doesn't care about anything else.

Some types of sensors are unique to each tire, and communicate with a
receiver mounted on the body near that tire, which then talks to the TPMS
computer. Other types communicate directly with the TPMS computer, meaning
the computer doesn't know which tire is low, and you need to check all
four.

The "unique sensor" type seems to be found mostly on vehicles marketed as
higher-end.

If the stem is metal, then you have a sensor screwed to the other end of
the stem.

If the stem is rubber, then there is nothing attached to the stem; instead,
TPMS uses the ABS to infer pressure differential from tire to ti too
great a difference in rotational speeds, then one tire is lower than the
other.

Thank you for providing an explanation.

Typically you can also get temperature information from the sensors.
However some (most) vehicles do not present the information to the
driver. e.g. while the sensors are reasonably accurate my old company
car (GM) would only display pressure information and my current BMW
dumbs it down even more and just displays a green/yellow/red indication
on a graphic.

They're not really unique, but when buying replacements there are
different models that communicate at different frequencies.
