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 ... 30 01...
means, for example, that the tyre was manufactured in the 30th week of
the year 2001.
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.
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

WARNING
•Only use those tyres or wheel rims which have been approved
for your model of Škoda Auto 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 public
roads may also become void as a result.
WARNING (continued)
•You must on no account drive at a higher speed than is permis-
sible 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 appropriately cautious
style of driving.
•Never fit tyres which have already been used without having
adequate knowledge of their previous history. Tyres 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 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.

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.
The wheel bolts must be clean and must turn easily.
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 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.
Only use radial winter tyres.
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 0.2 bar more than is
the case for summer tyres ⇒page 220.
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
⇒ .
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.
Exceeding the speed category of the tyre can lead to damage occurring.
Please pay attention to the notes if you decide to fit winter tyres
⇒ page 219.
You can also fit so-called “all-weather tyres” instead of winter tyres.
Please contact your Škoda dealer 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.
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 - 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.
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.

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 using special screws ⇒fig. 172 . One should check the air pressure in the spare wheel (at best when
generally checking the tyre air pressures - see sign on the fuel filler flap)
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 service station 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.
WARNING
•The hexagon socket in the handle of the screwdriver is used for
fitting on the wheel bolts. Neve r use it for tightening the wheel
bolts because you will not be able to achieve the necessary tight-
ening torque with this tool - risk of accident!
•The factory-supplied lifting jack is only intended for your model
of vehicle. On no account attempt to lift a heavier vehicle or other
loads - risk of injury!

– Have all the occupants get out. While changing a wheel, the
occupants of the vehicle should not stand on the road (it is
better 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 229
out of the luggage compartment.
Caution
If you have to change a wheel on a slope first block the opposite wheel
with a stone or similar object in order to secure the vehicle from unexpect-
edly rolling away.
Note
Comply with the national legal regulations.
Changing a wheel
Always change a wheel on a level surface as far as possible.
– Take off the full wheel trim/wheel trim cap ⇒page 232,
“Wheel trim caps*” or the caps ⇒page 232, “Wheel bolts with
caps*”.
– Slacken the wheel bolts ⇒ page 233.
– Jack up the vehicle until the wheel is clear of the ground ⇒page 233.
– Unscrew the wheel bolts and place them on a clean surface (cloth, paper etc.).
– Take off the wheel.
– Fit on the spare wheel and tighten the wheel bolts slightly.
– Lower the car.
– Tighten the wheel bolts firmly, alternately and diagonally using the wheel wrench ⇒page 233.
– Mount the full wheel trim/wheel trim cap or the caps.
Note
•All bolts must be clean and must turn easily.
•You must never grease or oil the wheel bolts!
WARNING
•If you find yourself in flowing traffic put on the hazard warning
lights system and place the warning triangle on the side of the road
at the prescribed distance from your vehicle while observing all
national legal provisions. In this way you are protecting not only
yourself but also other road users.
•Never start the engine with the vehicle sitting on the raised jack
- danger of suffering injury!

Subsequent steps
After changing the wheel, you must perform the following steps.
– Stow and attach the replaced wheel in the spare wheel well.
– Stow the vehicle tool kit in the space provided.
–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
must be 120 Nm.
– Have the defective tyre repaired as soon as possible.
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*
Removing
– Hook the clamp (found in the vehicle toolkit) into the reinforced edge of the full wheel trim.
– Push the wheel key through the clamp, support the wheel key at the tyre and pull off the wheel trim.
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.
Caution
Use the pressure of your hand, do not knock on the full wheel trim! Heavy
knocks mainly on the points where the full wheel trim has not been
inserted into the wheel, can result in damage to the guide and centering
elements of the full wheel trim.WARNING
It is necessary to observe the guidelines given on ⇒page 222,
“New tyres and wheels” if the vehicle is subsequently fitted with
tyres which are different to those it was fitted with at the works.

Slackening and tightening wheel bolts
Slacken the wheel bolts before jacking up the vehicle.
Slackening wheel bolts
– Push the wheel wrench fully onto the wheel bolt
3).
– Grasp the end of the wrench and turn the bolt about one turn to the left ⇒fig. 175.
Tightening wheel bolts
– Push the wheel wrench fully onto the wheel bolt
3).
– Grasp the end of the wrench and turn the bolt to the right until it is tight. Note
•Do not use the hexagon socket in the handle of the screwdriver for
slackening or tightening the wheel bolts.
•apply pressure carefully with your foot to the end of the wheel wrench
if it proves difficult to slacken the wheel bolts. Hold tight on the vehicle
when doing this and ensure that you have a steady position.
Raise vehicle
You have to raise the vehicle with a lifting jack in order to
be able to take off the wheel.
3)Use the appropriate adapter for slackening and tightening the safety wheel bolts
⇒ page 235.

– Position the lifting jack by selecting the jacking point - lower sill - which is closest to the wheel to be removed ⇒page 233,
fig. 176 .
– Position the lifting jack below the jacking point and move it up until its claw is positioned directly below the vertical web of the
lower sill.
– Align the lifting jack so that its claw grasps the web of the lower sill and the moving base plate of the jack is resting flat
against firm ground.
– Turn the lifting jack up further until the wheel is just clear of the ground.
Ground below the lifting jack which is soft and slippery can cause the
vehicle to slip off the jack. It is therefore always necessary to place the lift-
ingjack on a solid surface. Use a wide, stable base, if necessary. Use a
non-slip base (e.g. a rubber foot mat) if the surface is smooth, such as
cobbled stones, a tiled floor,etc.
Taking off and fitting on wheel
After you have slackened the wheel bolts and have raised the car
with the car jack, replace the wheel as follows:
WARNING
•Take suitable measures to prevent the base of the lifting jack
from slipping off - risk of injury!
•Not positioning the lifting jack at the specified points can result
in damage to the vehicle. The jack can also slip off if it does not
have sufficient grip - risk of injury!
•It is important to support the vehicle with suitable supporting
blocks if you wish to work under the lifted vehicle - risk of injury!

Fitting on wheel
– Push the spare wheel over the assembly pin.
– Screw in the wheel bolts and tighten them slightly with the aid
of the hexagon socket.
– Unscrew the assembly pin and screw in the remaining wheel bolt also slightly.
The wheel bolts must be clean and must turn easily.
The hexagon socket in the handle of the screwdriver makes it simpler to
fit on the wheel bolts. The reversible blade should be pulled out for this
step.
When fitting on unidirectional tyres, ensure that the tyres rotate in the
correct direction ⇒page 225.
Note
Do not use the hexagon socket in the handle of the screwdriver for slack-
ening or tightening the wheel bolts.
Securing wheels against being stolen
You need a special adapter for slackening the safety
wheel bolts.
– Pull off the full wheel trim/cap from the wheel hub or cap from
the safety wheel bolt.
– Push the adapter with its toothed side into the inner toothing of the safety wheel bolt right down in such a way
that only the outer hexagon is jutting out ⇒fig. 179.
– Push the wheel wrench fully onto the adapter .
– Slacken the wheel bolt, or tighten it firmly ⇒page 223.
– Reinstall the full wheel trim/wheel cap after removing the adapter or place the cap onto the safety wheel bolt.
