228 Wheels and tyres
– Also note that winter tyres are no longer effective when the
tread is worn down.
– After fitting the wheels you must always check the tyre pres-
sures. The correct tyre pressures are listed on the sticker on the
inside of the fuel tank flap ⇒ p age 223.
In winter road conditions winter tyres will considerably improve vehicle han-
dling. The design of summer tyres (width, rubber compound, tread pattern)
gives less grip on ice and snow. This applies particularly to vehicles equip-
ped with wide section tyres or high speed tyres (code letters H, V or Y on
the sidewall).
Only use winter tyres of the correct type approved for your vehicle. The sizes
of the winter tyres approved for your vehicle are listed in the vehicle docu-
mentation (e.g. EC Certificate of Conformity or COC document
cle documentation varies depending on the country of residence. See also
⇒ p age 226.
Winter tyres lose a great deal of their properties when the tread is worn
down to a depth of 4 mm.
The performance of winter tyres is also severely impaired by ageing, even if
the tread is still much deeper than 4 mm.
Winter tyres are subject to the following maximum speed limits according to
speed rating code letter: ⇒
Speed rating code Maximum speed limit
letter ⇒ p age 226
Q 160 km/h (140 mph)
S 180 km/h (140 mph)
T 190 km/h (140 mph)

Vehicles capable of exceeding these speeds must have an appropriate
sticker attached so that it is visible to the driver. Suitable stickers are availa-
ble from the SEAT Official Service and specialised workshop. Please note
regulations to this effect in your country.
"All-weather" tyres can also be used instead of winter tyres.
Using winter tyres with V-rating
Please note that the generally applicable 240 km/h (150 mph) speed rating
1)
). The vehi-
for winter tyres with the letter V is subject to technical restrictions; the max-
imum permissible speed for your vehicle may be significantly lower. The
maximum speed limit for tyres with a V-rating depends directly on the maxi-
mum axle weights for your car and on the listed weight rating of the tyres
being used.
It is best to contact a SEAT Official Service to check the maximum speed
which is permissible for the V-rated tyres fitted on your car on the basis of
this information.
WARNING
Exceeding the maximum speed permitted for the winter tyres fitted on
your car can cause tyre failure, resulting in a loss of control of the vehicle
– risk of accident.
