Tire Pressure Monitoring System (TPMS)
TPMS
, Tire Pressure Monitoring System is an electronic system designed to monitor the air pressure inside the
tires through special sensors mounted inside the wheels, which provide real-time tire-pressure information and
inside temperature data to the vehicle’s electronic control unit. Tire pressure system alerts the driver when the
tire pressure falls 20% below the recommended pressure, thus increasing your safety on the road.
This chapter describes the correct positioning of TPMS valve during the different working stages, in order to
avoid any damage.
Bead Loosening:
Place TPMS valve at
“2:00 o’clock”
position.
Start pushing on the tire bead using the upper
bead loosening disk.
Demounting tool positioning:
Place TPMS valve at
“2:00 o’clock”
position. Bring the
demounting tool into working position. While spinning the
wheel, insert the demounting tool into the drop center
level. Stop tire rotation when the valve reaches 11 o’clock
position.
Upper Bead demounting:
Spin the clamping chuck (clockwise) by pressing pedal
1
until the valve reaches
“1 o’clock”
position (at about 10 cm
from the demounting tool) so as to avoid possible damages
to the TPMS valve.
Warning
: Rim and Tire must spin together as one,
during bead demounting operations, to avoid displacement
of
TPMS
sensor.
Lower Bead demounting, with demounting tool:
Place TPMS valve below the demounting tool at
“12:00 o’clock”
position.
Lower Bead demounting, with bead loosening disk:
Place TPMS valve towards the bead loosening disk.
Lower Bead mounting:
Place TPMS valve at
“5:00 o’clock”
position, in any case
at about 10 cm from traction point.
Upper Bead mounting:
Place TPMS valve at
“5:00 o’clock”
position, in any case
at about 10 cm from traction point.
