marked on the sidewall, for example:
195/65 R15 91T
This contains the following information:
195 Tyre width in mm
65 Height/width ratio in %
R Tyre construction: Radial
15 Rim diameter in inches
91 Load rating code
T Speed rating
The tyres could also have the following information:•
A direction of rotation symbol
•
“Reinforced” denotes heavy-duty tyres.
The manufacturing date is also indicated on the tyre sidewall (possibly only
on the inner side of the wheel).
“DOT... 1105...” means, for example, that the tyre was produced in the 11th
week of 2005.
We recommend that work on tyres and wheels is carried out by an Authorised
Service Centre. They are familiar with the procedure and have the necessary
special tools and spare parts as well as the proper facilities for disposing of
the old tyres.
Any Authorised Service Centre has full information on the technical require-
ments when installing or changing tyres, wheels or wheel trims.
WARNING
•
We recommend that you use only wheels and tyres that have been
approved by SEAT for your model. Failure to do so could impair vehicle
handling. Risk of accident.
•
Avoid running the vehicle on tyres that are more than six years old. If
you have no alternative, you should dr ive slowly and with extra care at all
times.
•
Never use old tyres or those with an unknown “history of use”.
•
If wheel trims are retrofitted, you must ensure that the flow of air to the
brakes is not restricted. This could cause them to overheat.
•
All four wheels must be fitted with radial tyres of the same type, size
(rolling circumference) and the same tread pattern.For the sake of the environment
Old tyres must be disposed of accordi ng to the laws in the country concerned.
Note
•
For technical reasons, it is not generally possible to use the wheels from
other vehicles. This can also apply to wheels of the same model. The use of
wheels or tyres which have not been approved by SEAT for use with your
model may invalidate the vehicle's type approval for use on public roads.
•
If the spare tyre is not the same as the tyres that are mounted on the
vehicle - for example with winter tyres - you should only use the spare tyre for
a short period of time and drive with ex tra care. Refit the normal road wheel
as soon as possible.
Wheel bolts
Wheel bolts must be tightened to the correct torque.The design of wheel bolts is matched to the rims. If different wheel rims are
fitted, the correct wheel bolts with the right length and correctly shaped bolt

heads must be used. This ensures that wheels are fitted securely and that the
brake system functions correctly.
In certain circumstances, you may not
use wheel bolts from a different car -
even if it is the same model ⇒page 202.
WARNING
If the wheel bolts are not tightened correctly, the wheel could become
loose while driving. Risk of accident.•
The wheel bolts must be clean and turn easily. Never apply grease or oil
to them.
•
Use only wheel bolts which belong to the wheel.
•
If the prescribed torque of the wheel bolts is too low, they could loosen
whilst the vehicle is in motion. Risk of accident! If the tightening torque is
too high, the wheel bolts and threads could be damaged.Caution
The prescribed torque for wheel bolts for steel and alloy wheels is 120 Nm.Winter tyres
Winter tyres will improve the vehicles handling on snow and
ice.In winter conditions winter tyres will considerably improve the vehicles
handling. The design of summer tyre s (width, rubber compound, tread
pattern) gives less grip on ice and snow.
Winter tyres must be inflated to a pressure 0.2 bar higher than the pressures
specified for summer tyres (see sticker on tank flap).
Winter tyres must be fitted on all four wheels. Information on permitted
winter tyre sizes can be found in the vehicle's regis-
tration documents. Use only radial winter tyres. All tyre sizes listed in the
vehicle documentation also apply to winter tyres.
Winter tyres lose their effectiveness when the tread is worn down to a depth
of 4 mm.
The speed rating code ⇒page 227, “New tyres and wheels” determines the
following speed limits: ⇒
Q max. 160 km/h
S max. 180 km/h
T max. 190 km/h
H max. 210 km/h
In some countries, vehicles which can exceed the speed rating of the fitted
tyre must have an appropriate sticker in the driver's field of view. These
stickers are available from your Authorised Service Centre. The legal require-
ments of each country must be followed.
Do not have winter tyres fitted for unnecessarily long periods. Vehicles with
summer tyres handle better when the roads are free of snow and ice.
If you have a flat tyre, please refer to the notes on the spare wheel
⇒ page 227, “New tyres and wheels”.
WARNING
The maximum speed for the winter tyres must not be exceeded. Otherwise,
this could lead to tyre damage and thus, an accident risk.
For the sake of the environment
Fit your summer tyres in good time. They are quieter, do not wear so quickly
and reduce fuel consumption.

If and when

NoteThe hexagonal socket in the screwdri ver handle should be used for turning
wheel bolts only. Do not use it to loosen or tighten the wheel bolts.Changing a wheel Removing the wheel
– Using the hexagonal socket in the screwdriver handle, unscrew the slackened wheel bolts and place them on a clean surface.
– Take off the wheel.
– Store the defective wheel as described on ⇒page 233.
Fitting the spare wheel
– Put the spare wheel in place.
– Screw in the wheel bolts and tighten them lightly using the
hexagonal socket.
– Lower the vehicle on the jack.
– Tighten the wheel bolts firmly using the box spanner. Do not tighten the bolts in clockwise or anti-clockwise sequence.
Tighten them in diagonal sequence.Tyres with directional tread pattern
Tyres with directional tread pattern must be mounted so that they rotate in the
correct direction.
A directional tread pattern can be identified by arrows on the sidewall that
point in the direction of rotation. Alwa ys observe the direction of rotation indicated when mounting the wheel. This is important so that these tyres can
give maximum grip and avoid excessive noise, tread wear and aquaplaning.
If, in an emergency, you have to moun
t a wheel so it rotates in the wrong
direction, you must drive extremely care fully. The tyre will not give optimum
performance. This is particularly impo rtant when driving on wet roads. To
benefit from the advantages of tyres with directional tread pattern, the tyre
should be replaced as soon as possible so that it rotates in the correct direc-
tion.
Caution
•
The wheel bolts should be clean and turn easily. Do not grease or oil them.
•
The hexagonal socket in the screwdriver handle should be used for
turning wheel bolts only. Do not use it to loosen or tighten the wheel bolts.
After changing a wheel– Place the wheel with the defective tyre in the spare wheel bracket
⇒page 233.
– Have the flat tyre replaced as quickly as possible.
– Have the tightening torque of the wheel bolts checked as soon as possible with a torque wrench ⇒page 240.
– Check tyre pressure at the next opportunity.
– Avoid fast driving manoeuvres.
