Tyres
Restrictions
Not all tyres available on the market
currently meet the structural requirements.
We recommend that you consult a
Vauxhall Authorised Repairer concerning
suitable tyre makes.
These tyres have undergone special tests
to establish their reliability, safety and
specific suitability for Vauxhall vehicles.
Despite continuous market monitoring, we
are unable to assess these attributes for
other tyres, even if they have been granted
approval by the relevant authorities or in
some other form.
Further information – see page 226.
Winter tyres
3
Tyres of size 215/45 R 17, 225/45 R 17,
225/40
R 18 or 235/35 R 19 are not to
be used as winter tyres. Tyres of size
225/45
R 17 may be used as winter tyres
on the Astra TwinTop.
If winter tyres are in use, the spare wheel
may still be fitted with a summer tyre.
Use of the spare wheel may alter vehicle
handling. Obtain a replacement for the
faulty tyre as soon as possible, and have
the wheel balanced and fitted to the
vehicle.
Further information – see page 232.
Tyre chains
3
Restrictions
Tyre chains may be used on the front
wheels only.
We recommend the use of Vauxhall-tested
fine-mesh tyre chains that add no more
than 10 mm to the tyre tread and the
inboard sides (including chain lock).
Tyre chains are not permitted on
temporary spare wheel 115/70 R 16 or
on tyres of size 215/45 R 17, 225/45 R 17,
225/40
R 18 or 235/35 R 19. Tyre chains are
permitted on tyres of size 225/45 R 17 for
the Astra TwinTop.
Further information – see page 232.
Wheels
Wheel bolt tightening torque: 110 Nm.
Depending on the model variant, the spare
wheel may take the form of a temporary
spare wheel: vehicle driveability may be
altered by use of the spare wheel. Obtain a
replacement for the faulty tyre as soon
as possible, and have the wheel balanced
and fitted to the vehicle.
The spare wheel may have a smaller tyre
and a smaller rim than the wheels mounted
on the vehicle

:
Using the spare wheel may
alter vehicle handling. Have the defective
tyre replaced as soon as possible, balance
the wheel and have it mounted on the
vehicle.
Tyre pressure in bar / psi
2)
The specified tyre pressures are valid for
cold tyres. The increased tyre pressure
resulting from extensive driving must not
be reduced. The tyre pressures specified on
the following pages apply to both summer
and winter tyres.
Always inflate the spare wheel to the tyre
pressure for full load - see tables on
following pages.
Temporary spare wheel tyre pressure -
see tables on next page.
In vehicles with tyre pressure monitoring
system

there is an adapter in the valve
cap key. Screw adapter to valve before
attaching tyre pressure gauge –
see page 228.
Further information – see pages 226
to 233.
