Tyres
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 Vauxhallvehicles.
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 – page 230.
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 you use winter tyres 3, the spare wheel
may still be fitted with a summer tyre. If you
use the spare wheel the vehicle’s handling
may be altered. Obtain a replacement for
the faulty tyre as soon as possible, and
have the wheel balanced and fitted to the
vehicle.
Further information – page 236.
Tyre chains 3
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 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.
Tyre chains are permitted on tyres size 215/
45 R 17 only if the vehicle is factory-fitted
with 18" wheels.
Further information – page 236.
Wheels
Wheel bolt tightening torque: 110 Nm.
Spare wheel 3
Depending on the version, the spare wheel
may take the form of a temporary spare
wheel 3 : 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.
On vehicles with alloy wheels 3 the spare
wheel may have a steel rim.
The spare wheel may be fitted with a
smaller tyre
1)
and smaller wheel than the
wheels fitted to 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 3 to the tyre
pressure for full load - see tables on
following pages.
Temporary spare wheel 3 tyre pressure -
see tables on next page.
In vehicles with tyre pressure monitoring
system 3 there is an adapter in the valve
cap key. Screw adapter to valve before
attaching tyre pressure gauge – page 232.
Further information – pages 230 to 237.
