Interchanging tyres
Interchanging tyres.
Fig. 309
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. 309. The useful life of all the tyres will
then be about the same time.
New tyres or new wheels
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).
1) COC = certificate of conformity.
Wheels
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 match-
ed to the characteristics of the vehicle and
make a major contribution to good roadhold-
›››
ing 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
1)
or COC document ). The vehicle documen-
tation varies depending on the country of res-
idence.
A knowledge of tyre designations makes it
easier to choose the correct tyres. The fol-
lowing wording can be read on the sides of
the tyre:
215/60 R16 95V
This contains the following information:
215 Tyre width in mm
60 Height/width ratio in %
R Tyre construction: Radial
16 Rim diameter in inches
95 Load rating code
V Speed index
The manufacturing date is also indicated on
the tyre sidewall (possibly only on the outer
part):
DOT... 2216...
it means, for example, that the tyre was man-
ufactured in the 22nd week of 2016.
But note that with some types of tyre, the
actual tyre size can differ from the nomi-
nal size marked on the tyre (for instance
215/60 R16 95 V), and there may be signif-
icant differences in the contours of the
tyres, even though the tyres are marked
with the same nominal size. When replac-
ing the tyres, it is therefore important to
make sure that the actual size of the new
tyres does not exceed the dimensions of
the factory-approved makes of tyre.
Failure to observe this requirement can af-
fect the clearance needed for the tyres. If
the tyres rub against the bodywork, in cer-
tain circumstances the tyres, running gear
or bodywork and pipes may be damaged,
