WARNING
The tyres must be replaced at the latest when
the tread is worn down to the tread wear indi-
cators. Failure to follow this instruction could
result in an accident.
Especially in difficult driving conditions
●
such as wet or icy roads. It is important that
the tyre tread be as deep as possible and be
approximately the same on the tyres of both
the front and the rear axles.
● The scant driving safety due to insufficient
tread depth is particularly evident in vehicle
handling, when there is a risk of "aquaplan-
ing" in deep puddles of water and when driv-
ing through corners, and braking is also ad-
versely affected.
The speed has to be adapted accordingly,
●
otherwise there is a risk of losing control over
the vehicle.

Advice
Changing wheels
Interchanging tyres.
Fig. 178
To ensure that the wear is equal on all tyres
the wheels should be changed round from
time to time according to the system
›››
Fig. 178. The useful life of all the tyres will
then be about the same time.
Replacing wheels and tyres
All four wheels must be fitted with tyres of
–
the same type, size (rolling circumference)
and preferably the same tread pattern.
Tyres should be replaced at least in pairs
–
and not individually (i.e. both front tyres or
both rear tyres together).
Do not use tyres whose effective size ex-
–
ceeds the dimensions of the factory-ap-
proved makes of tyre.
If you wish to fit the vehicle with rims or
–
tyres different to those installed in manu-
facture, it is advisable to consult a SEAT Of-
ficial Service before purchasing them.
The tyres and wheel rims are an essential
part of the vehicle's design. The tyres and
rims approved by SEAT are specially matched
to the characteristics of the vehicle and make
a major contribution to good roadholding
›››
and safe handling .
The sizes of the rims and tyres approved for
your vehicle are listed in the vehicle docu-
mentation (e.g. EC Certificate of Conformity or
COC document 1) ). The vehicle documentation
varies depending on the country of resi-
dence.
Note for Italy: A SEAT Service Centre should
be consulted whether different sized wheels
or tyres to those originally fitted by SEAT may
be fitted, as well as the combinations al-
lowed between the front axle (axle 1) and
back axle (axle 2).
A knowledge of tyre designations makes it
easier to choose the correct tyres. The follow-
ing wording can be read on the sides of the
tyre:
