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.
let's see, 100 million cars means at least average of 10 gallons per car,
or 40 quarts per year. Nope not being used up there, unless they meant
'lifetime'. How about trucking industry, yeah, they must be the true
culprits of using all that oil. I'd be more worried about how one heavy 18
wheeler is equivalent to the traffic of 50,000 cars.
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.

Checking it with the tire gauge WAS the test. I should have mentioned
that this is only for cars or small truck tires. You cant do it on
bicycle tires, wheelbarrow tires or anything small. I have a farm
tractor, and those big tires have a totally different sound. I normally
find a gauge for them, or the small tires. Of course wheelbarrow tires
are not critical. Just dont over inflate or they blow up.
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.
You know it's time to clean the refrigerator
when something closes the door from the inside.
The one for my Toyoto 2007 truck had a sensor in the spare tire.
Now that truck has a bad sensor on one of the wheels, and a 2008 Camry has a
bad sensor also. Two differant places gave me a price of $ 50 and $ 70 to
replace them. I just let it go. They probably all will need to be replaced

I have the studs mounted on a set of rims that don't have the TPMS sensors.
The orange light flashes a few times when I start up and then goes solid.
It's not annoying enough to bother taping particularly since the panel is in
the center of the dash.
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.
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
Holding up his hand... I rotate and swap the winter and summer rims/tires
myself. I don't get any surprises if I have a flat since I don't torque the
nuts down to 400 ft-lbs like the Magnificent Hulk at the tire store. When it
comes time for a new set of shoes, I dump the set off in the morning and
pick them up at night rather than hanging around a tire store for hours.
Works for me.
Not enough snow/ice here to bother to change the automobiles out and the
4x4 PUs all have all-weather on them, anyway. When it does snow here,
it almost always blows so much that car can't do anything with the
drifting anyway because such low ground clearance so the tires really
make no difference.
Bought the wife a Buick Lucerne w/ the AWD and 20" rims so she'd have
something w/ more traction/clearance on the muddy roads when it does
(rarely last several years of drought) rain enough that the roads are
muddy...it's been useful a couple of times since had it for the purpose.
It's also actually a decent field-errand car for meals during harvest
time and the like as she's so short that getting in/out of and driving
the 4-wheelers is a lot of work and she doesn't like them. The Enclave
handles the sandy fields very well and has enough clearance to not high
center unduly or be a terrible fire hazard w/ the catalytic converter
