Tread Depth; Changing Tyre And Wheel Size - Opel AMPERA-E Owner's Manual

The available settings are:
● Light for comfort pressure up to
three people.
● Eco for Eco pressure up to three
people.
● Max for full loading.
Auto learn function
Each tyre pressure sensor has a
unique identification code. The
identification code must be matched
to a new wheel position after rotating
the wheels or exchanging the
complete wheel set and if one or more
tyre pressure sensors were replaced.
After changing wheels, the vehicle
must be stationary for approx.
20 minutes before the system
recalculates. The following relearn
process takes up to 10 minutes of
driving with a minimum speed of
20 km/h. In this event, w can be
displayed or pressure values can
swap in the Driver Information Centre.
If problems occur during the relearn
process, a warning message will be
displayed in the Driver Information
Centre.

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
Vehicle care
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.
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, vehicle
performance, including braking, ride
and handling characteristics, stability
and resistance to rollover may be
affected. If the vehicle has electronic
systems such as antilock brakes,
rollover airbags, traction control,
electronic stability control, the
performance of these systems can
also be affected. It may be necessary
to reprogramme the speedometer as
well as the nominal tyre pressure and
make other vehicle modifications.
