6.2. SPECIAL CASE OF TWIN WHEELS
VT TRUCK manages twin wheels completely automatically.
If you have a pair of twin wheels, start by activating the TPMS sensor of the outer wheel.
To do this, proceed in the exactly the same way as for a "single" wheel, then as soon as the
tool displays the result (green light PASS), move on to reading the inner wheel.
As for other wheel types, the TPMS tool should be held as close as possible to the wheel
valve to be read or to the sensor if attached to the outside of the tyre (see detailed
instructions on previous page).
Note that the TPMS sensor of the twin wheel (inner wheel) is usually positioned at 180
degrees to the outer wheel's sensor (see illustration below).
Simply read in the recommended order (see diagram on previous page) all wheels fitted with
TPMS sensors. VT TRUCK automatically handles all the wheels, including twin wheels.
If in doubt about the wheel read, remember that the TPMS tool automatically rejects
sensors already read, and so prevents duplication.
Example: If the tractor is equipped with 10 TPMS sensors and 10 pressure measurements
are displayed, this guarantees that they are for the 10 wheels of the vehicle.
