Wheels and tyres
WARNING
There should be adequate space between the
tyr e
s and the vehicle in accordance with the
vehicle design. If this is not the case, the
tyres may rub against parts of the running
gear, chassis or brake lines, leading to faults
in the brake system or to tread detachment,
and the risk of burst tyres.
● The true tyre dimension should not be
great
er than the dimensions of tyres manu-
factured and approved by SEAT and should
not rub against parts of the vehicle. Note
● Although ty r

es may be shown as being the
same size, the true dimensions of different
types of tyre may vary with respect to the
nominal size, or tread patterns may be differ-
ent.
● If you use tyres that are approved by SEAT,
you can be s
ure that the true tyre dimensions
will be correct for your vehicle. For other tyre
models, the tyre vendor should provide the
manufacturer's certificate with the tyre, indi-
cating that this type of tyre is suitable for
your vehicle. This certificate should always
be carried with the vehicle. Tyre pressure

e The correct tyre pressures for tyres fitted at
the f
act
or

y is shown on a label and is valid
for summer and winter tyres. This label
››› Fig. 252 is either on the driver door strut or
inside the fuel tank flap.
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
lea

st 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.
Checking tyre pressures
Tyre pressures should only be checked when
the vehicle has not been driven for more than
a few kilometres (miles) 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 the tyres. Tyre pressures
should be checked more often in colder re-
gions, and only when the vehicle has not
been driven recently. Always use a correctly-
operating tyre gauge.
● Adjust tyre pressures to the loads carried in
the vehic
le.
● After checking the pressure, always replace
the valv
e caps, and where applicable, ob-
serve the instructions given for adjusting the
tyre control system ››› page 234. »

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. Note
When checking tyre pressures, please ob-
serv e the in

structions for the tyre control sys-
tem ››› page 234. Wear indicator depth profile
Fig. 253
Tyre tread: tread wear indicators Tread depth
C
er
t

ain driving conditions require a deeper
tread, as well as needing the tread to be ap-
proximately the same on the front and rear
tyres. This is particularly important when
driving in winter, in cold temperatures and on
wet roads ››› .The minimum tread depth required by law in
the m
aj
ority

of cases is 1.6 mm (1/16 of an
inch), measured in the tread grooves next to
the tread wear indicators. Observe legal re-
quirements in each country.
Winter tyres lose much of their performance
when their tread has worn to 4 mm
(5/32 inch).
The tread depth of new tyres may vary, ac-
cording to the type and make of tyre and the
tread pattern.
Wear indicators on the tyre
The original tyres on your vehicle have
1.6 mm (1/16 inch) high ››› Fig. 253 tread
wear indicators running across the tread. A
number of these indicators are equally
spaced around the tyre tread. Certain marks
on the tyre walls (e.g. the letters “TWI” or
other symbols) indicate the position of the
wear indicators.
Tread wear indicators indicate if a tyre is
worn. They must always be replaced before
the tyre tread has worn to the level of the in-
dicator. WARNING
Driving with worn tyres is dangerous, and
ma y

lead to loss of control of the vehicle with
serious consequences. 292

Advice
● Adju s
t
speeds to within the limits indicated
(code letter on tyre) ››› .
S peed limit
A c ode l
etter indicating the speed limit is
stamped on all winter tyres ››› page 295.
In some vehicles, it is possible to set a speed
warning in the MFD (multifunction
display) menu on the instrument panel
›››  page 27.
If you use V-rated tyres the speed limits and
tyre pressure will be determined by engine
size. Please ask your technical service centre
for further information on the maximum per-
mitted speed and the required pressures for
the tyres.
All-wheel drive*
Thanks to its all-wheel drive, your car will
have plenty of traction in winter conditions,
even with the standard tyres. Nevertheless,
SEAT still recommend that winter tyres or all-
season tyres should be fitted on all four
wheels when winter road conditions are ex-
pected, mainly because this will give a better
braking response.
Please observe all instructions and warnings
when using snow chains ›››
 page 50. WARNING
Although winter tyres help to make driving
saf er in the w
inter, you should not take un-
necessary risks.
● Adjust your speed and driving style to visi-
bility
, road, traffic and weather conditions.
● Never exceed the maximum permitted
speed or loa
ds specified for the type of winter
tyre fitted on your vehicle. For the sake of the environment
When winter is over, change back to summer
tyr e

s when you have the time. In tempera-
tures above +7°C (+45°F), performance will
be improved if summer tyres are used. Fuel
consumption, wear and noises while driving
will all be reduced. Note
● If the v

ehicle is fitted with a tyre control
system, this should be “reprogrammed”
whenever a tyre is changed ››› page 236.
● Please ask at a technical service centre for
information about
the permitted sizes for
winter tyres. 296
