General comments
•New tyres do not offer optimal grip at first and should therefore be run
in for about 500 km at a moderate speed and an appropriately cautious
style of driving. You will also profit from longer tyre life.
•The tread depth of new tyres may differ because of design features
and the configuration of the tread (depending on the type of tyre and the
manufacturer).
•Drive over curbs on the side of the road and other such obstacles
slowly and, where possible, at a right angles in order to avoid damage to
tyres and wheel trims.
•Inspect your tyres from time to time for damage (punctures, cuts, splits
and bulges). Remove foreign bodies from the tyre profile.
•Damage to tyres and wheels is frequently not visible. Unusual vibra-
tions or pulling of the vehicle to one side could be a sign of tyre damage.
Please reduce your speed immediately and stop if you suspect that
a wheel is damaged. Inspect the tyres for signs of damage (bulges,
splits, etc.) If no visible damage is present, please drive at an appropri-
ately slow speed and carefully to the nearest specialist garage in order to
have your vehicle inspected.
•Also protect your tyres from contact with oil, grease and fuel.
•Immediately replace any dust caps of the valves which have got lost.
•Mark wheels before removing them so that their previous direction of
running can be maintained when mounted them again.
•Always store wheels or tyres which been removed in a cool, dry and,
where possible, dark place. Tyres which are not fixed to a wheel trim
should be stored upright. 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 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, low noise, wear-
and-tear and aquaplaning.
Further information concerning the use of unidirectional tyres
⇒
page 230.
WARNING
•New tyres during the first 500 km do not offer optimal grip and
should therefore be run approp riately - risk of accident!
•Never drive with damaged tyres - risk of accident!
Note
Please observe the various differing legal requirements regarding tyres.

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 indica-
tors are located at 6 - 8 points depending on the make and are evenly
spaced around the circumference of the tyre ⇒fig. 164 . 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 down. 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 “aqua- planing” (uncontrolled 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. You will then
obtain approximately the same life for all the tyres.
It may be advantageous to swap the tyres 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 Partners 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 there-
fore use the tyres and wheel rims which have been released for use by
Škoda Auto. They are exactly matched to the vehicle type and therefore
contribute significantly to good road holding and safe driving characteris-
tics
⇒ .
Only fit radial tyres of the same type on all 4 wheels, size (rolling circum-
ference) and, if possible, the same tread pattern on one axle.
Škoda Service Partners have access to the most current information
about which tyres we have released for use on your vehicle.

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 individual 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 conformity with the appropriate regula-
tions.
Note
It is not normally possible to fit wheels from other models of cars for tech-
nical 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 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 H, V or W 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.

For technical reasons, it is only permissible to fit snow chains with the
following wheel/tyre combinations:
Only use
fine-link snow chains . They must not project more than 9 mm
- including the chain lock.
Remove the full wheel trims before installing the snow chains.
Observe the national legal requirements relating to the use of snow chains
and 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
•Only fit snow chains from the range of Škoda genuine accessories.
•If snow chains are used, then switch off the traction control system
(TCS).

Spare wheel*
The spare wheel is stowed in the spare wheel well in the
luggage compartment below the floor covering.
The spare wheel lies in a well under the luggage compartment floor and is
fixed in place along with the vehicle tool kit box using special screws
⇒fig. 167 .
One should check the inflation pressure in the spare wheel (at best when
generally checking the tyre air pressures - see sign on the fuel filler flap
⇒ page 207) to ensure that the spare wheel is always ready to use.
Unidirectional tyres*
If you have such tyres on your vehicle, please refer to the notes below:
•The spare wheel provided with a car fitted with unidirectional tyres has
different dimensions. The wheel is provided with a warning sticker.
•After fitting on the wheel, the warning sticker must not be concealed
(e.g. by the wheel trim).
•Do not drive with this spare wheel at more than 80 km/h - risk of acci-
dent. Avoid accelerating at full throttle, sharp braking and fast cornering.
•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
occupants of the vehicle should not stand 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 236
out of the luggage compartment.

–Check the tyre pressure on the spare wheel just mounted as
soon as possible.
– Have the tightening torque of the wheel bolts checked with
a torque wrench as soon as possible. The tightening torque for
steel and light alloy wheels must be 120 Nm.
– Have the defective tyre repaired as soon as possible.
WARNING
It is necessary to observe the guidelines given on ⇒page 227,
“New tyres and wheels” if the vehicle is subsequently fitted with
tyres which are different to those it was fitted with at the works.
Note
•If you find, when changing the wheel, that the wheel bolts are corroded
and difficult to turn, the bolts must be replaced before checking the tight-
ening torque.
•Drive cautiously and only at a moderate speed to a workshop where
the tightening torque can be checked.
Full wheel trim*
Pulling off
– Hook the clamp found in the vehicle tool kit into the reinforced edge of the full wheel trim.
– Push the wheel key through the clamp, support the wheel key on the tyre and pull off the wheel trim ⇒fig. 168 .
Installing
– First press the full wheel trim onto the wheel at the valve opening provided. Then press the full wheel trim into the
wheel in such a way that its entire circumference locks
correctly in place.
