WARNING
● Alw
ays adapt the tyre pressure accordingly
when the vehicle load changes.
● A tyre with low air pressure has to flex a lot
more when the
vehicle is heavily loaded or at
high speeds, therefore causing overheating
to occur. Under these conditions, the tyre
bead may be released or the tyre may burst.
Risk of accident! For the sake of the environment
Under-inflated tyres will increase fuel con-
s umption. Wear indicators
Fig. 225
Tyre tread: tread wear indicators Tread wear indicators indicate if a tyre is
w
orn. The origin

al tyres on your vehicle have
1.6 mm high “tre
ad wear indicators” running
across the tread. Depending on the manufac-
turer, there will be 6 to 8 of them spaced at
equal distances around the tyre. Markings on
the tyre sidewall (for instance the letters
“TWI” or a triangle) indicate the positions of
the tread wear indicators.
The minimum tread depth required by law is
1.6 mm (measured in the tread grooves next
to the tread wear indicators). (Different fig-
ures may apply in other countries.) WARNING
The tyres must be replaced at the latest when
the tr e

ad is worn down to the tread wear indi-
cators. Failure to follow this instruction could
result in an accident.
● Especially in difficult driving conditions
suc
h 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
tre
ad 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,
otherw
ise there is a risk of losing control over
the vehicle. Changing wheels
Fig. 226
Interchanging tyres. To ensure that the wear is equal on all tyres
the wheel
s

should be changed round from
time to time according to the system
››› Fig. 226. 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 s ame type, s

ize (rolling circumference)
and preferably the same tread pattern.
– Tyres should be replaced at least in pairs
and not indiv

idually (i.e. both front tyres or
both rear tyres together).
– Do not use tyres whose effective size ex-
ceed

s the dimensions of the factory-ap-
proved makes of tyre. »

Wheels
●
Av
oid running the vehicle on tyres that are
more than 6 years old. If you have no alterna-
tive, you should drive slowly and with extra
care at all times.
● If wheel trims are fitted after the car is pur-
ch
ased, ensure that there is an adequate flow
of air for cooling the brake system. For the sake of the environment
Old tyres must be disposed of according to
the l a

ws in the country concerned. Note
● A S

EAT Service Centre should be consulted
to find out whether wheels or tyres of differ-
ent sizes to those originally fitted by SEAT
can be fitted, and to find out about the com-
binations allowed between the front axle
(axle 1) and the rear axle (axle 2).
● Never mount used tyres if you are not sure
of their
“previous history”.
● For technical reasons, it is not generally
pos
sible to use the wheels from other vehi-
cles. In some cases, this may also be true for
the same model of wheel. Wheel bolts
The wheel
bolts
ar
e matched to the rims.
When installing different wheels (for instance
alloy wheels or wheels with winter tyres) it is
important to use the correct wheel bolts with the right length and correctly shaped bolt
hea

ds. This ensures that wheels are fitted se-
curely and that the brake system functions
correctly.
The wheel bolts must be clean and turn easi-
ly.
A special adapter is required to turn the anti-
theft wheel bolts* ›››

Tyre monitoring systems Introduction WARNING
Unsuitable handling of the wheels and tyres
m a

y lead to sudden tyre pressure losses, to
tread separation or even to a blow-out.
● Check tyre pressures regularly and ensure
they ar
e maintained at the pressures indica-
ted. Tyre pressure that is too low could cause
overheating, resulting in tread detachment or
even burst tyres.
● Tyre pressure should be that indicated on
the label
when the tyres are cold at all times
››› page 303.
● Regularly check the cold inflation pressure
of the ty
res. If necessary, change the tyre
pressure of the vehicle tyres while they are
cold. ●
Re

gularly check your tyres for damage and
wear.
● Never exceed the maximum permitted
speed or lo
ads specified for the type of tyre
fitted on your vehicle. For the sake of the environment
Under-inflated tyres lead to increased fuel
c on

sumption and tyre wear. Note
● Driv in

g for the first time with new tyres at a
high speed can cause them to slightly ex-
pand, which could then produce an air pres-
sure warning.
● Only replace used tyres with those author-
ised b
y SEAT for the corresponding type vehi-
cle.
● Do not only rely on the tyre monitoring sys-
tem. R
egularly check your tyres to ensure
that the tyre pressure is correct and that the
tyres are not damaged due to puncture, cuts,
tears and impacts/dents. Remove objects
from the tyres only when they have not
pierced the tyres. 295
