•
The TPMS monitors only tyre pressure and temperature. It does not monitor
conditions such as tyre wear
•
The TPMS will not be able to detect an instant tyre burst and inform the driver in
advance
•
There may be the possibility of getting all the tyre location indicators on the TPMS
display blinking along with the TPMS telltale, on passing environment area prone
to heavy power lines and RF signal. It will come back to normal condition whenever
interference gets cleared
Fault at spare position will be displayed after swapping or if the spare itself has
a fault. If ‘spare tyre rectified’ is acknowledged without rectifying the fauIt, the
TPMS cannot detect it. It is the user’s responsibility to check the spare tyre
before starting the vehicle.
12.6.7 TPMS — Points to Remember
•
It is recommended to fill the pressure to 32 psi at a digital gauge station only
•
Every 15 days, inflate all the tyres up to 32 psi and inflation should be done at cold
condition/ambient temperature
•
Pressure deviation between the TPMS display and gauge will depend upon the
following factors:
– Atmospheric pressure
– Error in pressure filling gauge (not calibrated)
– Air leakage during inflation/deflation
•
TPMS measures the absolute pressure of the tyre, not relative pressure (gauge
pressure)
•
Pressure deviation is defined for 0.5 psi (min) and 3 psi (max)
•
The TPMS sensor has an in-built battery which has got an 8-10 years lifespan, so
the sensor needs to be replaced after 10 years
•
If the vehicle battery/fuse is disconnected and reconnected, it will update the
pressure after the vehicle is driven or sensor is activated
•
It is mandatory that manual learning should be performed if the vehicle tyres are
rotated or any of the tyres sensors are replaced, else the system will give a false
alert with respect to false location
•
At a time, only one tyre can be swapped with the spare wheel and then follow the
learning procedure
•
If more than one tyre needs to be learned, learn all 5 tyres as per manual learning
procedure
•
TPMS is only a warning or indicating device. Pressure and temperature values
displayed by the system is for indication prior to alert purposes only. The TPMS
system should not be used as a measuring device to correlate or calibrate
against other systems
•
During winter or in cold conditions, there may be chances of getting a pressure
alert with the corresponding tyre location indicator in the display, if the tyre
pressure is near the thresholds level. i.e. between 28 psi to 24 psi. However, this
alert will get cleared after driving a few kilometers depending upon the climatic
condition
12.7 Snow Chains
Snow chains cannot be used on these tires.
In case of harsh winter driving conditions, it is recommended using winter tires
with the same specifications for better stability, safety and performance.
