Tread Depth; Changing Tyre And Wheel Size - Vauxhall Vivaro C Owner's Manual

After initialisation system
automatically calibrates to new tyre
pressures during driving. After longer
drive the system will adopt and
monitor new pressures.
Always check tyre pressure with cold
tyres.
System has to be reinitialised when:
● Tyre pressure has been changed
● Load condition has been
changed
● Wheels have been swapped or
exchanged
The system will not warn
instantaneously on a tyre blow out or
a rapid deflation. This is due to
required calculation time.

Tread depth

Check tread depth at regular
intervals.
Tyres should be replaced for safety
reasons at a tread depth of 2-3 mm
(4 mm for winter tyres).
For safety reasons, it is
recommended that the tread depth of
the tyres on one axle should not vary
by more than 2 mm.
The legally permissible minimum
tread depth (1.6 mm) has been
reached when the tread has worn
down as far as one of the tread wear
indicators (TWI). Their position is
indicated by markings on the
sidewall.
If there is more wear at the front than
the rear, swap round front wheels and
rear wheels periodically. Ensure that
the direction of rotation of the wheels
remains the same.
Vehicle care
Tyres age, even if they are not used.
We recommend tyre replacement
every six years.
Changing tyre and wheel
size
If tyres of a different size than those
fitted at the factory are used, it may be
necessary to reprogramme the tyre
deflation detection system and make
other vehicle modifications.
Tyre deflation detection system
3 238.
Have the label with tyre pressures
replaced.
9 Warning
The use of unsuitable tyres or
wheels may lead to accidents and
will invalidate the vehicle
operating permit.
