From time to time this subject has come up.

I had an interesting? thought. Why doesn't someone come out with a gauge
that you push against the side of the tire that measures the deflection?
Beats removing a cap and fooling with a fussy tire air pressure gauge. It
might need to be calibrated by the user with a regular gauge depending on
type of tire. I'd buy one (if it didn't cost an arm and a leg).

What do you think?

I think it would be difficult to calibrate and have a cost considerably
higher than a $2.95 Slime pencil type tire gauge. I picked the Slime brand
because a review in a motorcycle magazine, where people tend to be less
casual about tire pressures, found it as good as any and better than most,
including the upscale digital models.

The industry is one step ahead of that.

A friend of mine bought a /used/ car and it has built-in tire pressure
sensors. She got a warning when one of the tires was low.

Since the car was used, that means the technology must have been around
for a while now.

Wife's car has these sensors. One went bad and showed tire to be under
inflated when it was inflated to the proper pressure. Dealer charged
$100 for a new sensor and $100 to put it in. I would have been tempted
to put a piece of masking tape over the red warning light. I have the
same model car but older without the sensors and I've never been worried
about it.

I rented a Toyota that had a screen that showed the pressure of each
tire. Warning light came on but did not say which tire and I had to
check them all with my gauge. Being a rental car, they varied by about
10 psi.

Our masters in DC have mandated this. Can't wait for the mandated
backup camera - more expensive **** to go bad.

Avoid the dealer. A local tire shop charges $10 for them installed if
replaced with new tires. Probably would have charged you $20 or so.

I would, but she won't.
Dealers won't do low cost repairs. Shops are tough too unless you're

That's what those sensors are for: making $$$ for the dealers.

That's exactly what I did... five years ago.

I have the studs mounted on a set of rims that don't have the TPMS sensors.

Well, I don't know any of your friends.

Not that I think about it, my 2001 LeSabre had a low pressure
indicator so the technology goes back quite a ways.

Probably close to 10 yr if not longer; not sure whether it's yet in the
"mandatory" column for new or not but haven't had a vehicle without it
since an '06 model LeSabre that had them.

The '06 was the "one is bad, not indication of which" variety of
indicator but all since all have at least an indication of which but
since '10 all have digital readout on each tire.

I've yet to have one go bad with four vehicles and a combined mileage of
probably 500k as a group, so in my mind they're _a_good_thing_ (tm) and
well worth the relatively small initial cost.

Somebody brought up the rear camera -- it's in the '10 Enclave and I
find it of little real value. I suppose if one had small kids it would
have a chance of saving a backup incident but I've had the vehicle for
five+ years now and I rarely, if ever, actually look at it. The backup
IR sensors are excessively sensitive and somewhat annoying; if I had
only a little more ambition I'd find the location of the beeper and put
something over it to mute them significantly. I suspect in an instance
or two over the life of a vehicle they'd have the possibility to prevent
a fender crunch but are exceedingly irritating trying to parallel park
in a tight spot as they start alarming far too far away from actual
impact. That _could_ be tuned; others may be better...

Yes, it is mandatory and has been for several years. The other "nice" part is if you run two sets of mounted tires (winter/summer), the second set also has to have them and that runs big bucks.

Don't see why that is a "must", necessarily. Of course, the system
won't function correctly without them, but don't see anything that would
make it mandatory.

I've not run a second set of rims on a passenger vehicle in at least 40
years; doubt if there's one in ten-thousand that do...

Why does the second set have to have them?

I was visiting a friend who had bought a new pickup at about that time,

on the ground. None of them were low. It was the spare tire.

On this pickup, the spare tire is mounted under the bed, with the valve

BTW, is these some benefit to having the valve up (and hidden)?

Now, w/o a full-size spare, not sure any have the sensor in the
spare...and don't think have ever had one even with the full-size rim
that had it in the spare. Certainly never had any indication of such on
any vehicle I've had (bunch of GM and one Chrysler in the lot).

Other than possibly minimizing vandalism and the very rare chance of a
thrown rock or the like damaging the stem can't think of any. Altho
I've had some that the hanger would only allow the rim to sit that way
as the centering portion was too high for the recess otherwise. OTOMH
can't think of which way any of the current three are...haven't had to
use the spare in years (which is actually quite an unusual occurrence
come to think of it with the number of flats get from stuff in the dirt
road that gets turned over almost every time they grade them. Of
course, the car tires aren't as rugged so small stuff that gets them
doesn't always actually cause a puncture in the trucks...

I had a pickup like that. I soon put an eyebolt in the truck bed, and
chained the spare to it. Drove like that for over 20 years. Seldom needed
it but when I did was a lot more convenient. And especially convenient to
check air pressure.

Since 2008, the way I read it.

Scroll down to the ' D. Impacts of the Final Rule' section. The estimate
was TPMS might save 120 lives per year and the sensor system would cost more
than any payback from fuel efficiency or tire mileage. In 2012 there were
33,561 traffic fatalities. This is down from 41,259 in 2007 though I expect
people not being able to afford gasoline may swamp out any tire pressure
problems.

It has been but the OP was asking for an alternative to a pressure gauge.
For example I have a set of aftermarket rims that I have the studs mounted
on. They don't have the sensors and for the price of 4 sensors I can check
the pressure periodically.

It has but I would not rely on it unless you have an actual pressure readout in real PSI. a "Low Tire" warning just means that the tire has 75% of the door sticker pressure, I'd prefer to know before that point.

Lucky you! The TPMS on my car were calibrated to
-5psi below the maximum pressure on my TIRES(41psi).


My door sticker says 30psi all four, so even if I keep
them at 32psi, my tires are still 'underinflated' according
to some guv'mint gadget installed in them! So I

Mine have a calibrate button (in the car) that you press when the
tires are inflated to my desired pressure. You act like your 41psi
calibration is set in stone. Are you sure?

That depends on the car and the setup. Some notify when down as
little as 2.5 PSI for sure - possibly some less.

Hi,
It gives actual pressure reading(mine in KPa) 2008 Acura MDX. I have 2

I think it would be difficult to calibrate and have a cost considerably
higher than a $2.95 Slime pencil type tire gauge. I picked the Slime brand
because a review in a motorcycle magazine, where people tend to be less
casual about tire pressures, found it as good as any and better than most,
including the upscale digital models.






The industry is one step ahead of that.

A friend of mine bought a /used/ car and it has built-in tire pressure
sensors. She got a warning when one of the tires was low.

Since the car was used, that means the technology must have been around
for a while now.

It has but I would not rely on it unless you have an actual pressure readout in real PSI. a "Low Tire" warning just means that the tire has 75% of the door sticker pressure, I'd prefer to know before that point.

Hi,
It does my car displays in KPa unit.

Beats removing a cap and fooling with a fussy tire air pressure gauge. It
might need to be calibrated by the user with a regular gauge depending on
type of tire. I'd buy one (if it didn't cost an arm and a leg).

A decade or more ago I was in a store. They had
tire pressure gauges, and for a dollar more,
Radial tire pressure gauges.

For two dollars more, you could probably get a left-handed tire pressure gauge.

You only needed those for the older Chrysler products with the left handed
lug nuts.

That radial air keeps twisting around and is much harder to measure.

But people with nitrogen filled tires need a nitrogen gauge.

I expect a coupon in the mail, one day soon.
Harbor Freight will have a 20% off sale on
left handed nitrogen filled radial tire
gauges which measure tire side wall deflection.
Comes with first set of batteries.

KenK:


The deflection of the tire sidewall is not the most accurate indicator of proper/over/underinflation.


Semi-OT: Has anyone seen that TV commercial where viewers are given 3 choices as to how much oil could be saved if everyone in America kept their tires properly inflated? I believe the correct answer was in the billions of gallons. Sobering!

I doubt it's that much. Be interesting if that
were true.

my 2014 Toyota Avalon
has some sort of automatic low tire pressure check

I wonder how this technology works...

Our 2002 Chrysler 300M has the TPMS (=Tire Pressure Monitoring System")
that shows the pressure in each tire, including the spare, and warns if
the pressure goes below a certain level: I don't remember for sure, but
I think if the pressure goes below 28psi (normal is 32psi). It
"recognizes" when a wheel has been exchanged with the spare.

Each TPMS sensor has a little battery-powered radio transmitter that
sends information to the on-board computer at regular intervals. I've
read that the batteries usually are not replaceable, so the sensors need
to be replaced eventually. Ours are still fine after 12 years.

From the 2008 model year on, such systems have been mandatory because
it was recognized that incorrect tire pressure can contribute to
accidents and that people don't seem to bother to check their tire
pressures these days.

Almost every new safety device has been resisted, either because people
didn't want to pay for it, or because they saw it as itself dangerous
("Electric headlights are too bright: they'll dazzle people; let's stick
to kerosene"), or both.
