New tyres and wheels
New tyres and wheels have to be run-in.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 make a major contribution to good road holding and safe
handling ⇒.
Tyres should be replaced at least in pairs and not individually (i.e. both front
tyres or both rear tyres together). A knowledge of tyre designations makes it
easier to choose the correct tyres. Radial tyres have the tyre designations
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... 1103...” means, for example, that the tyre was produced in the 11th
week of 2003.
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.
On vehicles with
four-wheel drive, all four tyres must always be fitted with
tyres of the same type, make and tread pattern, as otherwise the driveline can
be damaged by continuous differences in the wheel speeds. For the same
reason, only use a spare wheel with the same tyre dimensions as the normal
road wheels. You may also use the factory-supplied compact temporary spare
wheel.
WARNING
•
We recommend that you use only wh eels and tyres which 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 th at are more than six years old. If
you have no alternative, you should drive 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 and tyres
236wheels 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 extra 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 208.
After the wheels have been changed, the tightening torque of the wheel bolts
should be checked as soon as possible with a torque wrench ⇒. The tight-
ening torque for steel and alloy wheels is 120 Nm.
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 torque of the wheel bolts is to o 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 can 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 ty res (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 235, “New tyres and wheels” determines the
following speed limits for winter tyres: ⇒
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
