2005 SKODA SUPERB Owner's Manual

Wheels and Tyres
240
Wheel bolts
Wheels and wheel bolts are matched to each other in terms of design.
Each time you fit other wheels - e.g. light alloy wheels or wheels with
winter tyres - you must therefore also use the matching wheel bolts of the
correct length and shape of spherical cap. This is essential to ensure that
the wheels are tightly fitted and that the brake system operates properly.
If you retrofit wheel trims (or have this done), please also ensure that an
adequate flow of air remains assured for cooling the brake system.
Škoda dealers are instructed in the technical possibilities which exist
regarding converting or retrofitting wheels, tyres and wheel trim.
WARNING
•In case of incorrect treatment of the wheel bolts, the wheel can
loosen when the car is moving - risk of accident!
•The wheel bolts must be clean and must turn easily. However,
they must never be treated with grease or oil.
•If the wheel bolts are tightened to a too low tightening torque,
the rim can lossen when the car is moving - risk of accident! A tight-
ening torque which is too high can damage the bolts and threads
and this can result in perman ent deformation of the contact
surfaces on the rims.
Caution
The prescribed tightening torque of the wheel bolts for steel and light alloy
wheels is 120 Nm.
Winter tyres
The handling of your vehicle will be significantly improved when driving on
wintry roads and at temperatures below 7 °C if you fit winter tyres.
Summer tyres do not offer the same grip on ice and snow at a temperature
below 7 °C because of their construction (width, rubber blend, tread
pattern). This applies in particular to vehicles which are equipped with
low-profile tyres or high-speed tyres (code index V, W or Y on wall of
tyre).
Winter tyres must be mounted on all four wheels to obtain the best
handling characteristics.
You must only fit those types of winter tyre which are approved for your
vehicle. The permissible sizes of winter tyres are stated in your vehicle
documents. Approvals may differ because of national legislation.
Please remember that the tyres should be inflated to 20 kPa (0.2 bar)
more than is the case for summer tyres ⇒page 236.
Winter tyres no longer offer the same winter performance once the tyre
tread has worn down to a depth of about 4 mm.
Ageing also causes winter tyres to lose most of their winter performance
properties - even in cases where the remaining tread depth is still clearly
more than 4 mm.
Speed restrictions apply to winter tyres as well as to summer tyres
⇒ page 238, ⇒ .
You can fit winter tyres of a lower speed category to your vehicle provided
that you also do not drive faster than the permissible maximum speed for
such tyres, even if the possible maximum speed of your vehicle is higher.
The corresponding tyre category can damage the tyres when exceeding
the permissible maximum speed.
Please pay attention to the notes if you decide to fit winter tyres
⇒ page 235.

You can also fit so-called “all-weather tyres” instead of winter tyres.
Please contact your specialist garage if there are any points which are not
clear who will be able to provide you with information regarding the
maximum speed fo
r your tyres.
WARNING
You must on no account drive your car at more than the permis-
sible maximum speed for your winter tyres - risk of an accident
resulting from tyre damage and loss of control over your car.
For the sake of the environment
Fit your summer tyres on again in good time since summer tyres offer you
better grip and handling on roads which are free of snow and ice as well
as ar temperatures below 7 °C - the braking distance is shorter, there is
less tyre noise, tyre wear is reduced and fuel consumption is reduced.
Note
Please observe the various differing legal requirements regarding tyres.
Unidirectional tyres*
The direction of rotation of the tyres is marked by arrows on the wall of
the tyre . This indicates the direction of rotation of the tyre, and it is essen-
tial that the tyres are fitted on to run in this direction. Only then are the
tyres able to provide the optimal properties in terms of grip, low noise,
wear-and-tear and aquaplaning.
Should it be necessary to fit on a spare wheel in exceptional cases with a
tyre not dedicated to the running direction or in opposite running direction,
please adopt a cautious style of driving as the tyre is no longer able to provide optimal grip and handling in such a situation. This particularly
important on wet roads. Please refer to the notes
⇒page 247, “Spare
wheel”.
You should have the defective tyre replaced as soon as possible and
restore the correct direction of rotation on all tyres
Snow chains
Snow chains can be used only for wheel sizes 6J x 16 ET 40 or 6J x 16
ET 37. Your Škoda Dealer can provide you with more detailed information.
Snow chains must only be mounted on the front wheels.
When driving on wintry roads, snow chains improve not only traction, but
also the braking performance.
Only use fine-link snow chains . They must not project more than 15 mm
- including the chain lock.
Remove the full wheel trims if you wish to fit snow chains to the wheels.
Observe the national legal requirements relating to the maximum vehicle
speed with snow chains.
WARNING
Please pay attention to the information in the supplied fitting
instructions of the snow chain manufacturer.
Caution
You must take the chains off as soon as you drive on roads which are free
of snow. They adversely affect the handling of your vehicle, damage the
tyres and are rapidly destroyed.

Accessories and replacement parts
Škoda vehicles have been built according to the latest discoveries in
safety engineering. Thus one should not change the condition in which the
vehicle was delivered from the manufacturer without some thought.
The following guidelines should be observed when a vehicle is to be retro-
fitted with accessories, have technical changes made to it or a part has to
be replaced at some time in the future.
•Advise should always be obtained from a Škoda dealer before buying
any accessories and before making any technical changes ⇒ .
•This is particularly the case when accessories are bought in a foreign
country.
•Škoda Genuine Accessories which have been released for use and
Skoda original parts can be obtained from Škoda dealers. They will install
them professionally and correctly.
•All Škoda original accessory which is listed in the catalogue such as
tilting roofs, spoilers, wheels etc. must have an official stamp of approval.
•Radios, aerials and other electrical accessories should only be
installed by an authorised workshop.
•The guidelines issued by Škoda Auto must be observed when making
technical changes.
•This is to ensure that no technical damage occurs to the vehicle, that
travelling and operating safety are maintained and that the chnages are
permissible. Škoda dealers undertake this work professionally or refer it
to an specialist company in special cases.
Any damage which is done caused by technical changes made
without consulting a Skoda dealer is excluded from the guarantee.
WARNING
•We advise you, in your own interest, to only use Škoda Genuine
Accessories and Škoda original parts which have been expressly
approved for use on your Škoda. Reliability, safety and suitabiliity
have been established for these Škoda original parts.
•We cannot guarantee suitability of installation into your vehicle
of other products despite keeping a constant eye on market devel-
opments (also not in the case where there is an attestation or
permission can be produced).
Technical changes
Interference on the electronic components and their software can lead to
operational faults. This interference can also impair not directly affected
systems because of the networking of the electronic components. This
means that the operating safety of your vehicle can be considerably jeop-
ardized, a greater wear of vehicle parts can occur and finally the vehicle
registration documents expire.
We trust that you will understand that your Škoda dealer cannot be liable
for damage resulting from unprofessional work.
We therefore recommend that you have all work carried out with Škoda
original parts at your authorised Škoda dealer.
