WARNING (Continued)
You must have your tyres replaced with new ones at the latest when the
■
wear indicators have been worn down.
Worn tyres impair necessary adhesion to the road surface, particularly at
■
high speeds on wet roads. This could lead to "aquaplaning" (uncontrolled
vehicle movement – "swimming" on a wet road surface).
WARNING
Having the correct tyre inflation pressure is always the driver's responsi-
■
bility.
Too low or too high inflation pressure impairs handling.
■
If the inflation pressure is too low, the tyre will have to overcome a higher
■
rolling resistance. This will cause a significant increase in the temperature
of the tyre, especially at higher speeds. This can result in tread separation
and a tyre blowout.
In the event of very fast tyre inflation pressure loss, such as a sudden tyre
■
failure, an attempt should be made to bring the vehicle carefully to a stop
without sudden steering movements and without any hard braking.
CAUTION
If a spare wheel is used that is not identical to the fitted tyres, the following
■
must be observed » page 159, Spare and temporary spare wheel.
The tyres must be protected from contact with substances such as oil,
■
grease and fuel, which could damage them. If the tyres come into contact with
these substances, then we recommend you have this checked out in a special-
ist workshop.
If, in the case of puncture occurring, the spare tyre with a non-bound direc-
■
tion or an opposite direction of rotation must be mounted, then drive carefully.
The best properties of the tyre are no longer present in this situation.
For the sake of the environment
Old and unserviceable tyres are classified in a special environmentally haz-
■
ardous category. These must be disposed of in accordance with national legis-
lation.
Tyres that are insufficiently inflated increase your fuel consumption.
■
Note
We recommend that any work on the wheels or tyres be carried out by a spe-
■
cialist garage.
We recommend that you use wheel rims, tyres, full wheel trims and snow
■
chains from ŠKODA Original Accessories.
Service life of tyres
Fig. 141 Principle sketch: Tyre tread with wear indicators/open fuel filler
flap with a table detailing the tyre sizes and tyre inflation pressures

Read and observe and
The service life of tyres depends on the inflation pressure, driving style and
other circumstances.
Tyre pressure
Check the tyre pressure, including that of the spare wheel, at least once a
month and also before setting off on a long journey.
The tyre pressures for tyres are shown on the inside of the fuel filler
flap » Fig. 141 – .
The tyre pressure for the spare wheel should correspond to the highest pres-
sure specified for your vehicle.
Always check the inflation pressure when the tyres are cold. Do not reduce the
higher pressure on warm tyres.
