Tread Depth; Wheel Covers - Chevrolet 2013 VOLT Owner's Manual

Temperature Compensation
Cold tyres decrease the tyre
pressure; warm tyres increase the
tyre pressure. The tyre pressure
monitoring system considers this
effect for the warning messages.
The tyre pressure value displayed in
the DIC shows the actual tyre
pressure. Therefore, it is important
to check tyre pressure with cold
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).
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 is the same as before.
Tyres age, even if they are not
used. We recommend tyre
replacement every 6 years.
Vehicle Care

Wheel Covers

Wheel covers and tyres that are
factory approved for the respective
vehicle and comply with all of the
relevant wheel and tyre combination
requirements must be used.
If the wheel covers and tyres used
are not factory approved, the tyres
must not have a rim protection
ridge.
Wheel covers must not impair brake
cooling.
WARNING
Use of unsuitable tyres or wheel
covers could lead to sudden
pressure loss and thereby
accidents.
