Ty re l i fe
The life of your tyres very much depends on the following points:
Tyre pressure
The working life of tyres will be shortened considerably if the tyres are insufficiently
or over-inflated and this will have an advers e effect on the handling of your vehicle.
Correctly inflated tyres are of particular importance when travelling at high speeds .
It is therefore good to check the pressure at least once a month and also before
setting off on a long trip. Please do not forget the spare wheel when checking the
tyres. The tyre inflation pressures for summer tyres are indicated on the inside of the fuel
filler flap
⇒fig. 183 . The inflation pressures for winter tyres are 20 kPa (0.2 bar)
higher than those for summer tyres ⇒page 203.
The tyre pressure should be at the highest pressure specified for your vehicle at all
times.
On cars with full wheel trim, valve extensions are fitted in place of dust caps
⇒ fig. 184 . It is not nece ssary to unscrew the valve extensions in order to check and
alter the inflation pressure of the tyre.
Always check the inflation pressure of ty res when cold. Do not reduce the higher
pressure of warm tyres. Adapt the inflation pressure of the tyres accordingly if your
vehicle is carrying a signi ficantly higher payload.
Driving style
Fast cornering, sharp acceleration and brak ing (squealing tyres) increase wear-and-
tear on your tyres.
Balancing wheels
The wheels of a new vehicle are balanced. There are a wide range of influences
when driving which may result in an imbalance and which makes themselves felt
through vibration in the steering.
You should have the wheels rebalanced since any imbalance increases wear-and-
tear on the steering, the suspension and tyres. A wheel must also be rebalanced
when a new tyre is fitted and each time a tyre is repaired.
Wheel alignment errors
Incorrect wheel alignment at the front and rear will not only increase wear-and-tear
on the tyres but will also has an adverse effect on vehicle safety. Contact your
specialist garage if you no tice any unusual tyre wear.
WARNING
•If the inflation pressure is too low, the tyre must perform a greater flexing
work. At higher speeds the tyre will warm up as a result of this. This can
result in tread separation and even a tyre blowout.
•Immediately replace the damaged rims or tyres.

For the sake of the environment
Tyres which are insufficiently inflated increase your fuel consumption.
Wear indicators
The base of the tread of the original tyres has wear indicators 1.6 mm high, installed
at right angles to the direction of travel. These wear indicators are located at 6 - 8
points depending on the make and are evenly spaced around the circumference of
the tyre ⇒fig. 185 . Markings on the walls of the tyres through the letters “TWI”,
triangular symbols or other symbols identify the position of the wear indicators.
A remaining tread of just 1.6 mm, measured in the grooves of the tread next to the
wear indicators, means that your tyres have reached their legally permissible
minimum tread depth.
WARNING
•You must have your tyres replaced with new ones at the latest when the
wear indicators have been worn do wn. The legally permissible minimum
tread depth should be observed.
•Worn tyres do not provide the necessary adhesion to the road surface at
high speeds on wet roads. One could experience “aquaplaning” (uncon-
trolled movements of the vehicle - “swimming” on a wet road surface).
Changing wheels around
If significantly greater wear is present on the front tyres, we recommend changing
the front wheels around with the rear wheels as shown in the diagram ⇒fig. 186 .
You will then obtain approximately the same life for all the tyres.
It may be advantageous to swap the tyre s over “crosswise” when certain types of
wear characteristic arise on the running surface of the tyres (but not in the case of
unidirectional tyres). Škoda Service Pa rtners can provide you with details.
We recommend that you change the wheels around every 10 000 km in order to
achieve even wear on all wheels and to obtain optimal tyre life.
New tyres and wheels
Tyres and wheel rims are important design elements. One should therefore use the
tyres and wheel rims which have been released for use by Škoda Auto. They are
exactly matched to the vehicl e type and therefore contribu te significantly to good
road holding and safe driving characteristics ⇒ .
Only fit radial tyres of the same type on all 4 wheels, size (rolling circumference)
and, if possible, the same tread pattern on one axle.
The Škoda Service Partners have access to the most current information about
which tyres we have released for use on your vehicle.

We recommend that you have any work rela ting to tyres or wheels carried out by
your Škoda Service Partner . Your dealer has all of the necessary special tools and
replacement parts available plus the required specialist knowledge and is also in a
position to properly dispose of the old tyres. A large number of Škoda Service Part-
ners also have an attractive range of tyres and wheels available.
The tyre/wheel combinations which are appr oved for your vehicle are indicated in
your vehicle documents. Approval and lice nsing may differ according to the legis-
lation prevailing in individual countries.
Proper knowledge of the tyre data makes it easier for you to select the correct type
of tyre. Tyres do, for example, have the following inscription on their walls:
205 / 60 R 15 91 V
What this means is:
The following speed restrictions apply to tyres. The
date of manufacture is also stated on the tyre wall (possibly only on the inside
of wheel):
DOT ... 20 04...
means, for example, that the tyre was manufactured in the 20th week of the year
2004.
Any spare wheel which differs from the tyres fitted to the vehicle (e.g. winter tyres
or low-profile tyres) should only be used only for a short time in the event of a
puncture and when adopting an appropriately cautious style of driving. It should be
replaced as quickly as possible by a normal wheel.
WARNING
•Only use those tyres or wheel rims which have been approved for your
model of Škoda Auto a.s. vehicle. Failure to observe this instruction will
adversely affect the road safety of your vehicle - risk of accident! Approval
and licencing of your vehicle on publ ic roads may also become void as a
result.
•You must on no account drive at a hi gher speed than is permissible for
your tyres - risk of an accident resulting from tyre damage and loss of control
over your vehicle.
•Tyres which are 6 years old or more should only be fitted in exceptional
cases and when adopting an approp riately cautious style of driving.
•Never fit tyres which have already been used without having adequate
knowledge of their previous history. Ty res age even if they have not been
used at all or only very little. A spare tyre must only be used in exceptional
cases and only then when adopting an appropriately cautious style of
driving.
•Do not, where possible, replace indivi dual tyres but at least replace them
on both wheels of a given axle at the same time. Always fit the tyres with the
deeper tread depth to the front wheels.
For the sake of the environment
Old tyres must be disposed of in conf ormity with the appropriate regulations.

Using the systemSafetyDriving TipsGeneral MaintenanceBreakdown assistanceTechnical Data
Note
It is not normally possible to fit wheels from other models of cars for technical
reasons. This may also apply in certain circumstances to the wheels of the same
type of vehicle.
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.
The Škoda Service Partners are instructed in the technical possibilities which exist
regarding converting or retrofitti ng 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 tightening torque
which is too high can damage the bolts and threads and this can result in
permanent 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 if you fit winter tyres. Summer tyres do not offer the same grip on ice, snow
and at temperatures below 7 °C because of their construction (width, rubber blend,
tread pattern). This applies in particul ar 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 char-
acteristics.
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 200.
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 201,
⇒ .
You can fit winter tyres of a lower speed ca tegory 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 199.
You can also fit so-called “all-year 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 for your
tyres.

WARNING
You must on no account drive your car at more than the permissible
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 tempera-
tures 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 th e tyre, and it is essential 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, lo w 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 o pposite 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 particul arly important on wet roads. Please refer
to the notes ⇒page 209, “Spare wheel”.
You should have the defective tyre replac ed 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 Service Partner 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.
Note
We recommend that you use snow chains from the Škoda genuine accessories.

Accessories and replacement parts
Škoda vehicles have been built according to the latest discoveries in safety engi-
neering. Thus one should no t change the condition in which the vehicle was deliv-
ered from the manufacturer without some thought.
The following guidelines should be observed when a vehicle is to be retrofitted with
accessories, have technical ch anges made to it or a par t has to be replaced at some
time in the future.
•Advise should always be obtained from a Škoda Service Partner before buying
any accessories and before making any technical changes ⇒.
•This is particularly the case when acce ssories are bought in a foreign country.
•Škoda Genuine Accessories which have b een released for use and Skoda orig-
inal parts can be obtained from Škoda Se rvice Partners. 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 access ories should only be installed by an
authorised workshop.
•The guidelines issued by Škoda Auto a.s. must be observed when making tech-
nical 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
Service Partners 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 a.s. dealer is excluded from the guarantee.
WARNING
•We advise you, in your own interest, to only use Škoda Genuine Accesso-
ries and Škoda original parts which have been expressly approved for use on your Škoda. Reliability, safety and su
itabiliity have been established for
these Škoda original parts.
•We cannot guarantee suitability of installation into your vehicle of other
products despite keeping a constant ey e on market developments (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 opera-
tional faults. This interference can also impair not directly affected systems because
of the networking of the electronic co mponents. This means that the operating
safety of your vehicle can be considerably jeopardized, a greater wear of vehicle
parts can occur and finally the vehi cle registration documents expire.
We trust that you will understand that yo ur Škoda Service Partner cannot be liable
for damage resulting from unprofessional work.
We therefore recommend that you have a ll work carried out with Škoda original
parts at your authorised Škoda Service Partners.
WARNING
Work or modifications on your vehicle, which have been carried out unpro-
fessionally, can cause operational faults - risk of accident!

•The inflation pressure for this spare wheel is identical to the inflation pressure
of the standard tyres.
•Use this spare wheel only to reach the nearest specialist garage as it is not
intended for continuous use.
Changing a wheel
Preliminary work
The following steps should be carried out before actually changing the
wheel.
– If it is necessary to change a wheel, park the vehicle as far away as possible from the traffic flow. The place you choose should be level.
– Have all the occupants get out. While changing a wheel, the occu-
pants of the vehicle should not stan d on the road (e.g. behind a crash
barrier).
– Apply the handbrake firmly.
–Engage 1st gear or if your vehicle is fitted with an automatic gearbox,
position the selector lever into position P.
– If a trailer is coupled, uncouple it.
– Take the vehicle tool kit and the spare wheel ⇒ page 209 out of the
luggage compartment.
