When it comes to tire safety, fifth wheel
owners recognize the importance of being
alerted to a potential tire problem before
the problem escalates into a safety issue.
Tire blowouts on a fifth wheel or on the
tow vehicle often result in extensive
damage being done to the underside of
the trailer or the tow vehicle.
If a tire overheats and catches fire then
the problem instantly turns into a nightmare
scenario for all involved. A blowout on
the tow vehicle will often result in difficulty
controlling both the fifth wheel and the
Tire Pressure Monitoring Systems (TPMS)
have come a long way since their inception.
Todays systems offer features that play
an important role in identifying a potential
tire problem before it becomes a safety
Why Monitor Both Temperature &
Having a TPMS that monitors both tire
pressure and tire temperature helps cover
all of your bases when pulling a fifth
Often a tire will start to show signs
of failure by an increase in heat which
will then be followed by a decrease in
air pressure. Catching the problem long
before it starts to escalate is of great
importance. It gives you time to reduce
speed and get to a safe location where
you can visually check the problem tire.
If a bearing on the axle of the fifth
wheel is starting to overheat or perhaps
the brakes are binding or getting hot,
the tire temperature should alert you
to the problem. With a TPMS that only
monitors tire pressure you would get no
warning until the tire starts to lose
pressure. That loss of pressure could
be the blowout which you are trying to
detect before it occurs.
How the TPMS
The TPMS consists of transmitters that
screw onto the valve stems of the fifth
wheel and tow vehicle tires.
Each transmitter has its own unique identification
number that is recognized by the monitor.
These unique identification numbers ensure
that the monitor knows which transmitter
it is getting data from. If there is another
fifth wheel near yours that also has the
same TPMS system, your monitor will not
be affected. A monitor resides in the
tow vehicle. The transmitters from each
tire send tire pressure and temperature
data to the monitor. Should a specific
tire experience a sudden air loss or increase
in heat, the transmitter immediately alerts
the monitor which will then alert the
driver with audible and visual warnings.
The tire that is experiencing a failure
is shown on the monitor.
