Here’s Why This Kind of Tire is Stupid

rev up your engines today I’m going to
teach you everything you need to know about your tire pressure monitoring
system on your car now in theory the tire pressure monitoring system of your
car is simple when you’re driving your car and the light comes on like this
that means that theoretically one of your tires is low on air so of course
get a tire pressure gauge to check the tire pressures could easily just be a
tire that’s low on air I checked them all and be sure to check the spare too
because some of them have sensors in the spare and to understand what could be
wrong here’s how the systems work each tire has a vowel stem where you add the
air and check the air well inside that valve stem there is a broadcast unit and
it is broadcasting the tire pressure to a computer module in your car and when
it sees that one or more tires are either too low or too high in pressure
it turns that warning light on telling you got a problem with tire pressure now
this is a wireless system so guess what a lot of stuff can go wrong normally
it’s the sensors because think about it each one is a broadcast unit well they
have batteries and the batteries go bad over time they last so many years they
go up they don’t broadcast you don’t get a signal down to puts the warning light
on but the only way you can tell that is with a fancy machine like this autel TPMS
machine even if you find out what’s wrong the battery is inside the valve
stem here on the tire right inside your tire and since the batteries one on most
of them are non replaceable you got to buy the whole valve stem assembly with
the battery in a sensor in it you still have to take the tire off of the rim
take the assembly apart put a batter in put it back together again like I said
normally you can’t even do that you just have to take the old one apart then
throw it away and then buy a new one and stick it in and that can cost a lot of
money and guess what you got four tires there’s a sensor in each one they all
work the same way with batteries so eventually they’re all gonna go out
let’s say you had to replace all four of them generally they’re around 100 bucks
apiece then you got to pay the labor to take
the tires apart each and put them back on again so you’re gonna spend six to
eight hundred dollars replacing them all even if you had a tire machine
you’d still like to buy one of these machines because once you put the new
sensors in they have to be calibrated to work with the system which this machine
can do yes but you’re gonna go on by one of these things this particular one
works pretty good it’s about a three hundred and thirty dollar machine now
snap-on makes a fifteen hundred dollar one that works a little bit better but
either way you’re looking at a ton of money so you’re gonna end up paying
somebody else to do the job now just for kicks for testing a system
I’m testing the front-left one with this machine you can see it shows the
pressure now we can test each one of them we push the trigger now they’re
tested right rear that sends a signal then we test the left rear we send the
signal and go to the wheel got the signal they’re all okay but now it’s
gonna check the trunk the trunk failed so the reason the system isn’t working
it’s because the spare tires low on air this is a cheap fix
oh we move all the crap out of the way and put air in a spare tire the leg came
on because the spare tire sensors showing its long remember to check even
the spare when you got a late-model car like this but let’s say you’re bad news
go dad and eventually all four will go bad as you keep the car long enough you
can get an entire system like this for less than 100 bucks that you can easily
install yourself and not at the mess taking the tires apart paying a mechanic
to set it all up again comes with four sensors you can see they’re labeled but
not only are they labeled here when you take it out it even says on it front
right so you can’t get confused all you have to do is take off your valve stem
cover that comes off and then you screw this cap on that’s it and of course you
use all four stick on the all the tires now this particular one the Zus is an
app that works on your phone by the new generation one the early generation
wants from a year or two ago they had bad sensors that would either leak or
they go bad after a quick period of time you need to get the new version or
realize there are hundreds of Chinese companies that make similar ones some
work on an app some you get a little screen that you can put anywhere that
gives the readouts there’s lots of them out there do research use whichever one you want they all work the same way and they’re
big advantages these babies have a lot better inside you can on scrool you can
replace the battery so not only is it easy to install you don’t have to take
the stupid tire apart it just screws on if the battery goes bad you just thought
screw it and put a new battery in it almost all the models are made that way
so you can easily replace the battery when it goes bad instead of paying a
mechanic maybe a thousand bucks to replace them all take all your tires
apart and then rebalance them then you can read all the pressures you can get
warnings you can set it up any pressure you want for the maximum high the
maximum low the maximum differential being a computer it’s got all kinds of
stuff on but like I said there are a zillion of these tire monitoring system
you can buy they’re very handy devices and since they cost so little
you’re better off it’s filled with one of these then you are putting on four
sensors and the labor and then knowing eventually if you keep your car long
enough those batteries will go bad then you got to go all over again why not
just override the system with these very simple devices that you can easily do
yourself you don’t need a mechanic you don’t need the computer to reset it
because you reset it yourself on your phone or in the dash unit that it comes
with you don’t have to buy that 320 to $1500 machine and best of all you don’t
have to take your tires apart with the tire machine change all the parts on
then put them together and have the tires rebalance you don’t have to do
anything except unscrew the cap and screw these on so if you’re having
problems with your tire pressure monitoring system on your car now you
know what you can actually do about it yourself, so if you never want to miss
