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. »

Advice
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

Advice

lar.
Under-inflation or over-inflation will reduce
the life of the tyres considerably and also im-
pair the car's handling ››› . It is essential to
m aint
ain the c

orrect tyre pressures, especial-
ly if driving at high speeds. Incorrect tyre
pressure causes premature wear and could
cause tyre blow-out.
The pressure should therefore be checked at
least once a month and before starting a
journey.
As a general rule, the pressures given are for
cold tyres. When the tyres are hot, the pres-
sures are greater.
Never deflate a hot tyre in order to obtain the
required pressure. This could result in very
low tyre pressures which may lead to sudden
blow-outs.
Tyre pressure monitoring system
Check tyre pressures only when the vehicle
has not been driven for more than a few kilo-
metres at low speeds in the past three hours.
● The tyre pressures should be checked regu-
larly, and on
ly when the tyres are cold. Al-
ways check all tyres, including the spare
wheel. Tyre pressures should be checked
more often in colder regions, and only when
the vehicle has not been driven recently. Al-
ways use a correctly-operating tyre gauge. ●
Adjust
tyre pressures to the loads carried in
the vehicle.
● After adjusting the tyre pressure, check that
the caps
are properly screwed on.
The spare wheel or temporary spare wheel
must always be kept at the maximum pres-
sure stipulated. WARNING
If tyre pressures are too high or too low, the
tyr e m

ay deflate or burst suddenly while driv-
ing. This could result in a serious accident.
● If the tyre pressure is too low, they could
overhe
at, resulting in tread detachment or
even burst tyres.
● When driving at high speeds and/or fully
loaded, the ty
re could suddenly overheat,
burst or be subject to tread detachment, with
the resultant loss of control of the vehicle.
● Tyre pressures which are too high or too
low reduc
e the service life of the tyre, affect-
ing the vehicle's performance.
● Tyre pressures should be checked regularly,
at le
ast once a month and before long jour-
neys.
● Adjust the pressures of all the tyres to the
vehicl
e load.
● Never deflate excess pressure from hot
tyre
s. CAUTION
● Tak e c

are not to tilt the manometer when
placing it on the valve. Otherwise, the valve
may be damaged.
● If tyre valves are not protected by caps, or if
the caps
are not screwed on correctly, they
may become damaged. Check that the caps
are identical to the standard caps and have
been correctly tightened. For the sake of the environment
Under-inflated tyres will increase fuel con-
sumption. Wear indicator depth profile

Advice
tyres wear too quickly, have the wheel align-
ment c
hec
ked at a specialised workshop. WARNING
If you notice unusual vibration or the car pulls
to one s ide whi

le driving, this may indicate
that one of the tyres is damaged.
● Reduce speed immediately and stop, while
obser
ving the highway code.
● Check the wheels and tyres for damage.
● Never carry on driving on worn tyres or
wheels. Reque
st qualified assistance immedi-
ately.
● If there is no visible exterior damage, drive
slowly
and carefully to the nearest special-
ised workshop and have the vehicle checked. Tyre monitor system* 

b utt
on The tyre control lamp compares wheel revolu-
tion
s
and w

ith it, the wheel diameter of each
wheel using the ESC. If the diameter of a
wheel changes, the tyre control lamp 
lights up. The wheel diameter changes when:
● Tyre pressure is insufficient.
● The tyre structure is damaged.
● The vehicle is unbalanced because of a
load.
● The wheel

s of one axle are under more
pres
sure (for example, driving with a trailer or
on steep slopes).
● The vehicle is fitted with snow chains.
● The temporary spare wheel is fitted.
● The wheel on one axle is changed.
Tyr
e pressure adjustment
On adjusting tyre pressure or changing one
or more wheels, the ››› Fig. 176 button must
be kept pressed down, with the ignition on,
until an acoustic signal is heard.
If the wheels are under excessive load (for ex-
ample, driving with a trailer or heavy load),
the tyre pressure must be increased to the
recommended value for a full load (see the
sticker on the inside of the fuel flap). If the
tyre monitor system button is pressed down,
the new tyre pressures are confirmed. The tyre pressure control lamp
 lights up
If
the tyre pressure of a wheel is much lower
than the value set by the driver, then the tyre
pressure control lamp ››› will light up.
WARNING
● When the tyr e pr

essure control lamp lights
up, reduce speed immediately and avoid any
sudden turning or braking manoeuvre. Stop
when possible, and check the tyre pressure
and status.
● The driver is responsible for maintaining
correct
tyre pressures. For this reason, tyre
pressure must be regularly checked.
● Under certain circumstances (e.g. when
driving in a s
porty manner, in winter condi-
tions or on a dirt track) the tyre control lamp
may light up belatedly or may function incor-
rectly. Note
If the battery is disconnected, the yellow
warnin g l

amp  lights up after turning the
ignition on. This should turn off after a brief
journey. 206
