Winter Service - Seat altea Owner's Manual

For the sake of the environment
Old tyres must be disposed of according to
the laws in the country concerned.
Note
For technical reasons, it is not generally
●
possible to use the wheels from other vehi-
cles. 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 vehi-
cle'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 (e.g.
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
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 should not use
wheel bolts from a different vehicle, even if it

is the same model

After the wheels have been changed, the
tightening torque of the wheel bolts should
be checked as soon as possible with a torque

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 tightening torque of the wheel bolts
is too low, they could loosen whilst the vehi-
cle is in motion. Risk of accident! If the tight-
ening torque is too high, the wheel bolts and
threads can be damaged.
CAUTION
The prescribed tightening torque for wheel
bolts for steel and alloy wheels is 120 Nm.

Advice
. The tightening torque for steel
mer tyres (width, rubber compound, tread
pattern) provide less grip on ice and snow.
Winter tyres must be inflated to a pressure of
0.2 bar (2.9 psi/20 kPa) higher than the pres-
sures specified for summer tyres (see sticker
on fuel tank flap).
Winter tyres must be fitted on all four wheels.
Information on permitted winter tyre sizes
can be found in the vehicle's registration
documentation. Use only radial winter tyres.
All tyre sizes listed in the vehicle documenta-
tion 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 179, 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 stickers are available from your
technical service. The legal requirements of
each country must be followed.
Do not have winter tyres fitted for unnecessa-
rily long periods. Vehicles with summer tyres
