Wheels and tyres
The service life of tyres is dependent on tyre
pr e
s
sure, driving style, the care they receive
and the correct fitting.
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 our
critical to good road holding and safe han-
dling.
Avoiding damage to tyres and wheels
● If you have to drive over a kerb or similar
obs
tacle, drive very slowly and as near as
possible at a right angle to the kerb.
● Inspect the tyres regularly for damage
(punct
ures, cuts, cracks, dents).
● Remove any foreign bodies found on the
outside of the ty
re tread and ensure that they
have not passed through the wall of the tyre
››› page 205.
● In addition, the instructions for tyre control
syst
ems should always be observed.
● Replace damaged or worn tyres as soon as
poss
ible ››› page 205.
● Regularly check tyres for non-visible dam-
age ››

› page 205.
● Never exceed the maximum permitted
speed or loa
ds specified for the type of tyre
fitted on your vehicle ››› page 208.
● Do not allow tyres (including the spare
wheel) to come int
o contact with aggressive substances, grease, oil, fuel or brake fluid
›››
.
● Lost valve caps should be replaced imme-
di at
ely

.
Tyres with directional tread pattern
Tyres with directional tread pattern have
been designed to operate best when rotating
in only one direction. An arrow on the tyre
sidewall indicates the direction of rotation on
tyres with directional tread ››› page 208. Al-
ways observe the direction of rotation indica-
ted when mounting the wheel. This guaran-
tees optimum grip and helps to avoid aqua-
planing, excessive noise and wear.
If the tyre is mounted in the opposite direc-
tion of rotation, drive with extreme caution,
as the tyre is no longer being used correctly.
This is of particular importance when the
road surface is wet. Change the tyre as soon
as possible or remount it with the correct di-
rection of rotation.
Interchanging tyres
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. 173. The useful life of all the tyres will
then be about the same time.
SEAT recommends you take the vehicle to a
specialised workshop to have the tyres
changed. Tyres over 6 years old
Tyr

es are subject to an ageing process as a
result of physical and chemical processes.
This may affect their performance. Tyres
which are stored for long periods of time
without being used, harden and become
more fragile than tyres which are in constant
use.
SEAT recommends that tyres over six years
old are replaced with new tyres. This also ap-
plies to tyres (including the spare wheel)
which appear to be in perfect condition on
the outside and which have a tread depth
within the values stipulated by the Law ››› .
The d at
e of

manufacture, part of the tyre
identification number (TIN), indicates the age
of the tyre ( ) ››› page 208.
Storing tyres
Mark tyres when you remove them to indicate
the direction of rotation (left, right, forwards,
backwards). This ensures you will be able to
mount them correctly when you replace
them. When removed, the wheels and/or
tyres should be stored in a cool, dry and pref-
erably dark location. Do not place tyres
mounted on the wheel in a vertical position.
Protect tyres not mounted on wheels from
dirt by storing them in suitable bags and
standing them on the ground on their tread. »

WARNING
Aggressive fluids or substances could result
in v i
sible or invisible damage with the conse-
quent risks.
● Always ensure that tyres do not come into
contact
with chemical products, oil, grease,
fuel, brake fluid or other aggressive substan-
ces. WARNING
Old tyres, even if they have never been used,
ma y

lose air or burst unexpectedly while driv-
ing, resulting in serious accident or damage.
● If tyres are over six years old, they should
only be u
sed in an emergency and with ex-
treme caution. For the sake of the environment
Old tyres must be disposed of by qualified
personnel ac

cording to the laws in the coun-
try concerned. Wheels
The design of wheel bolts is matched to the
rims. If
diff
er

ent rims are fitted, the correct
wheel bolts with the right length and correct-
ly shaped bolt heads must be used. This en-
sures that wheels are fitted securely and that
the brake system functions correctly
››› page 72. For technical reasons, it is not generally pos-
sibl

e to use the wheels from other vehicles.
In some cases, this may also be true for the
same model of wheel.
The tyres and rims approved by SEAT are spe-
cially matched to the characteristics of the
vehicle and are critical to good road holding
and safe handling.
Wheel bolts
Wheel bolts must be tightened to the correct
torque ››› page 72.
Beadlock wheel rims
Beadlock wheel rims have various compo-
nents. These are joined together by special
bolts using a special procedure. This ensures
good performance, a better seal, improved
safety and wheel run out. Therefore, worn
rims should always be replaced and must on-
ly be repaired in a specialised workshop.
SEAT recommends visiting a technical service
››› .
Wheel rims
w

ith bolted trims
Wheel rims may be fitted with interchangea-
ble trim parts which are attached to the rim
using self-locking bolts. Worn trims should
only be replaced at a specialised workshop.
SEAT recommends visiting a technical service
››› . WARNING
The use of worn or damaged wheel rims could
mak e driv

ing more dangerous and result in
serious accidents and damage.
● Only wheel rims which have been approved
for use w
ith your vehicle should be used.
● Inspect wheel rims regularly for damage
and repl
ace as required. WARNING
If the bolted joints of wheel rims with bolted
ring trims ar

e not correctly tightened or loos-
ened, this could result in serious accident.
● Never loosen the bolted joints of wheel
rims with bo
lted ring trims.
● Any work relating to wheel rims with bolted
rims shoul
d be carried out at specialised
workshop. SEAT recommends taking your car
in for technical service. Note
A SEAT Service Centre should be consulted to
find out whether wheel s

or tyres of different
sizes to those originally fitted by SEAT can be
fitted, and to find out about the combinations
allowed between the front axle (axle 1) and
the rear axle (axle 2). 202

as soon as possible ››› page 203.
It is advisable to check the spare wheel or
temporary spare wheel tyre pressure when
checking the rest of the vehicle wheels at
least once a month. The spare wheel should
have the highest pressure allowed for the ve-
hicle ››› page 203. The sticker situated on the
temporary spare wheel shows the tyre pres-

Incorrect handling of the spare wheel or the
tempor ar

y spare wheel can cause loss of ve-
hicle control, producing collisions or other
serious accidents and injury.
● Never use the spare wheel or the temporary
spar
e wheel if it is damaged or worn to the
wear indicator.
● In some vehicles the spare wheel is smaller
than the origina
l tyres. This can be seen on a
sticker showing the text “80 km/h” and
“50 mph”. This text indicates the maximum
velocity permitted for this type of tyre.
● Never drive faster than 80 km/h (50 mph).
Avoid po
werful acceleration, hard braking
and taking corners at high speed.
● Never drive more than 200 km with a tem-
porary

Tyres with directional tread pattern
Tyres with directional tread pattern have
been designed to operate best when rotating
in only one direction. An arrow on the tyre
sidewall indicates the direction of rotation on
tyres with directional tread. Always observe
the direction of rotation indicated when
mounting the wheel. This guarantees opti-
mum grip and helps to avoid aquaplaning,
grip, noise and wear.
If the tyre is mounted in the opposite direc-
tion of rotation, drive with extreme caution,
as the tyre is no longer being used correctly.
This is of particular importance when the
road surface is wet. Change the tyre as soon
as possible or remount it with the correct di-
rection of rotation. Tyre load rating

● Check the ty

re pressure at least once per
month. Checking the tyre pressure is very im-
portant. If the tyre pressure is too high or too
low, there is an increased danger of accidents
- particularly at high speeds.
● If the tightening torque of the wheel bolts
is t
oo low, they could loosen while the vehi-
cle is in motion. Risk of accident! If the tight-
