Changing wheels aroundIf 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. 163 .
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). Specialist garages are familiar 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 wheelsTyres 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 vehicle type and th erefore contribute 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 specialist garages 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 a
specialist garage . The specialist garages have all of the necessary special tools and
replacement parts available plus the requir ed specialist knowledge and are also in
a position to properly dispose of the old tyres. A large number of specialist garages
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:
195 / 65 R 15 91 T
What this means is:
The following speed restrictions apply to tyres.

Technical Data
Winter tyresThe 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 partic ularly applies to vehicles which are equipped with low-
profile tyres or high-speed tyres (code index H or V 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 type s of winter tyre which are approved for your vehicle.
The permissible sizes of winter tyres are stated in your vehicle documents.
Approvals may differ becaus e of national legislation.
Please remember that the tyres should be in flated to 20 kPa (0.2 bar) more than is
the case for summer tyres ⇒page 175, fig. 161 .
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 mo st of their winter performance proper-
ties - 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 177,
⇒ .
You can fit winter tyres of a lower speed ca tegory to your vehicle provided that you
also do not drive faster than the permis sible maximum speed for such tyres, even
if the possible maximum speed of your ve hicle is higher. The corresponding tyre
category can damage the tyres when exceeding the permissi ble maximum speed.
Please pay attention to the notes if you decide to fit winter tyres ⇒page 175.
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 ti me 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.Snow chainsSnow 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.
For technical reasons, it is only permissi ble to fit snow chains with the following
wheel/tyre combinations:
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.
