Cranky old white hairs like me wonder what\'s wrong with a walk
around and a tire pressure gauge.

Aren\'t the \"per wheel\" pressures displayed in real-time? Can\'t
the driver notice that a tire is low or, in our case, high (due
to increasing ambient temperatures)?

Having real-time information on when you\'ve blown a tire can help you
get the car off the road more quickly, and on some low-sitting vehicles
can help prevent further damage to the car

??? I don\'t think the reading is that real time is it? When you\'ve blown a tire, do you really need a dash gauge tell you?

I\'ve never actually \"blown\" a tire as in a catastrophic failure where
the pressure drops to almost nothing instantly that I recall, so
\"blowout\" is the wrong term.

I\'ve hit nails, etc. and started pretty rapidly losing pressure, though,
like 38...37...36...35 where you can count one-mississippi between each
psi and yes in the late-model cars it\'s happened to me in it pops up the
tire pressure display once it hits the low pressure-threshold and you
can see it fall in real time, or close to it

Same here For what should be a few dollars I was asked for about $ 70
per wheel. Just like the high price of the fobs that many cars are now
using.

On late-model cars you can use two fobs to program infinite additional
blank fobs.

If you\'ve lost a fob and only have one then things get real interesting.
In theory in the US you only need one fob to make a second (vs Canada
where you need at least two to do anything) however the process for
programming a replacement yourself on Chevy cars at least becomes 10x
more byzantine with only one, and the chances you brick your remaining
fob and/or brick the car trying to do it yourself are IMO at least 50/50.

I just called a locksmith the time I was in that situation.

Those used to suck but I guess nowadays some manufacturers like Audi can get
their indirect sensors pretty accurate and they can somehow detect if all four
tires are low or high, also

ABS has to sense small changes in rotational speed to determine the onset of
a skid. So, that sets the threshold for how \"flat\" a tire can be and be
noticeable.

Not sure if detecting all four in an identical -- but over/under-inflated
state -- would be possible without another reference. E.g., if you had a road
facing camera (like for lane monitoring), you might be able to deduce speed
over ground and compare that to the \"sensed\" speed based on tire rotation
(assuming the dashed lines on roads have some standard governing their
spacing?)

Cranky old white hairs like me wonder what\'s wrong with a walk

Most late-model cars will show you the tire pressure of each tire on
the dash display, also.

It\'s annoying when on occasion they rotate the tires but then forget
to reprogram the computer so it knows what wheel which sensor is on,
this requires a tool:

There are some systems that DON\'T place pressure sensors on the wheels.
To clarify on Chevrolets at least the direct sensors integrated into the
valve stems of the tires; I don\'t know if all brands do that with direct
sensors though but it seems common.

If just the module fails you can usually save the tire by pulling and
de-flating the tire a bit then slipping the new module around the stem &
hopefully can get away without re-balancing the wheel if you do this in
your driveway
They, instead, detect \"low pressure\" by noticing the different rates of
rotation of the tires (based on the ABS sensors). (\"poor mans TPMS\")

if all four tires are low or high, also

I\'ve been told in the Teslas, the sensor is mounted so it passes close to a pickup that both inductively couples for transmitting a signal, but also to supply power to the sensor. That is why the tire pressure won\'t show up until you are something like a quarter mile down the road. It needs a few rotations to fire up the pressure sensor.

Seems like an ideal application for vibrational/piezoelectric energy
scavenging e.g.

Cranky old white hairs like me wonder what\'s wrong with a walk around and a tire pressure gauge.

So 3xn^2 + 5=42 gives you n=3.51... So it wasn\'t that. Somebody knew what they were doing and put the vehicle deep into loss of control without warning operator. Loss of control is a conditional parameter, operator doesn\'t know about it until the vehicle is maneuvered.

I\'ve never had that sort of failure, but even so, I don\'t think these things update in real time in that sense. A psi per second might take some seconds to show up. Some sensors have batteries, which means they are updating as little as possible. Mine are wheel powered.

My tire leaks have either been so slow, the shop can\'t find the leak, or the blow NOW! Once it took a few seconds, very few. I felt the car handling oddly as I took an exit and it was flat by the time I got to the bottom and was a wild ride going down! It\'s one thing to get a flat on the road, on a sharp curve it\'s something else!

I\'ve blown tires twice (or more) from hitting high concrete curb. First time, i drag it a few hundred feet to a nearby tire store. Second time, i drove around a mile with a hole on the side wall, no air, on run-flat tire. Tire pressure monitoring won\'t make any difference. I only drive on run-flat tires now.

This says federal requirements are that it has to send an update at
least every 20 min:

<https://www.motor.com/magazine-summary/tpms-sensors-hit-retirement-age/>

That was 10 years ago though. I think it\'s largely implementation-dependent.

It doesn\'t seem inconceivable that the reporting interval isn\'t fixed,
that a sensor could log the pressure every 100mS or something and if
dP/dt isn\'t too high it only broadcasts every minute (more power hungry
than just logging), but it begins reporting more often proportional to
dP/dt.

I don\'t know how much of this is the car\'s responsibility and how much
the sensor does but the \"sensor\" ICs are highly configurable uPs in
their own right, the datasheet of this one as an example is 176 pages long:

<https://www.farnell.com/datasheets/2618548.pdf>

My tire leaks have either been so slow, the shop can\'t find the leak, or the blow NOW! Once it took a few seconds, very few. I felt the car handling oddly as I took an exit and it was flat by the time I got to the bottom and was a wild ride going down! It\'s one thing to get a flat on the road, on a sharp curve it\'s something else!

I\'ve definitely had the presume monitor on my old Gen 1 Volt alert me to
a tire deflating from a puncture so that I could pull off before it got
to the flappa-flappa point, no wild ride. It naturally happened at about
11 pm on a pouring rainy night about the middle of nowhere in
northeastern CT.

But the emergency goop-injector and air compressor aworked surprisingly
well and I was rolling again in about 15 min. If it had been a bust
severe enough to deflate the tire in just a couple seconds like a side
wall blowout, I doubt gooping it would\'ve helped much.

Well if you fuckin\' clobber the thing on a curb such that you rupture
the sidewall and it goes flat in one second then no it won\'t make any
difference. Have you considered not clipping curves, granma?

It\'s ok I\'m just messing with ya. I ripped a rocker panel right off on a
concrete stoop one time in a dark parking lot a few years ago,
fortunately on that car it was just a piece of grey ABS plastic held on
with clips, $82 NOS on the eBay.

??? I don\'t think the reading is that real time is it? When you\'ve blown a tire, do you really need a dash gauge tell you?

I\'ve never actually \"blown\" a tire as in a catastrophic failure where
the pressure drops to almost nothing instantly that I recall, so
\"blowout\" is the wrong term.

I\'ve hit nails, etc. and started pretty rapidly losing pressure, though,
like 38...37...36...35 where you can count one-mississippi between each
psi and yes in the late-model cars it\'s happened to me in it pops up the
tire pressure display once it hits the low pressure-threshold and you
can see it fall in real time, or close to it
I\'ve never had that sort of failure, but even so, I don\'t think these things update in real time in that sense. A psi per second might take some seconds to show up. Some sensors have batteries, which means they are updating as little as possible. Mine are wheel powered.

My tire leaks have either been so slow, the shop can\'t find the leak, or the blow NOW! Once it took a few seconds, very few. I felt the car handling oddly as I took an exit and it was flat by the time I got to the bottom and was a wild ride going down! It\'s one thing to get a flat on the road, on a sharp curve it\'s something else!

I\'ve blown tires twice (or more) from hitting high concrete curb. First time, i drag it a few hundred feet to a nearby tire store. Second time, i drove around a mile with a hole on the side wall, no air, on run-flat tire. Tire pressure monitoring won\'t make any difference. I only drive on run-flat tires now.
Well if you fuckin\' clobber the thing on a curb such that you rupture
the sidewall and it goes flat in one second then no it won\'t make any
difference. Have you considered not clipping curves, granma?

You have always been a twit, you usually hide it better though. It was an exit ramp and the tire had worn through on the inside tread because the rear was out of alignment from an accident years before. It developed that one flat, and never wore the tires oddly again. Weird. It was an old Nissan/Datsun (from the time they were changing the name) and only lasted 70,000 miles before the manual transmission locked in 5th gear.
