Opel Corsa: Wheels and tyres / 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.
Tyres age, even if they are not used.
We recommend tyre replacement
every 6 years.
The tyre deflation detection system
continually checks the rotation speed
of all four wheels and warns on low
tyre pressure condition once vehicle
is driving...
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...
Other information:
The system monitors the driver's level
of vigilance at speeds above
65 km/h. A camera at the top of the
windscreen detects variations in
trajectory compared to the lane
markings.
If the trajectory of the vehicle
suggests a certain level of
drowsiness or inattention by the
driver, the system triggers the first
level of alert...
