2 STEEL + In the example, there are 4 layers be-
1 NYLON low the tread: 1 layer of rayon (artifi-
cial silk), 2 layers of steel reinforce-
ment and 1 layer of nylon.
Information for the end consumer concerning the com-
parative values of the established base tyres (standar-
dised test procedures):
TREADWEAR Relative service life of the tyre, with
280 respect to specific US standard test.
TRACTION AA Braking capacity of tyre on wet sur-
face (AA, A, B or C).
TEMPERATURE A Tyre temperature resistance at higher
test speeds (A, B or C).
If there are different letters, they are specific codes of
the tyre manufacturer or specific national codes.
a) The letters TIN refer to the tyre serial number.
Tyres with directional tread patterns
Tyres with directional tread pattern have
been designed to operate best when rotating
in only one direction. An arrow on the tyre
sidewall indicates the direction of rotation on
tyres with directional tread. Always observe
the direction of rotation indicated when
mounting the wheel. This guarantees opti-

mum grip and helps to avoid aquaplaning,
grip, noise and wear.
Tyre load rating
The load rating code indicates the maximum
load in kilogrammes each wheel can carry
(load capacity).
91 615 kg (1,356 pounds)
93 650 kg (1,433 pounds)
95 690 kg (1,521 pounds)
97 730 kg (1,609 pounds)
99 775 kg (1,709 pounds)
Speed rating
The speed rating indicates the maximum
speed permitted for the tyres.
P max. 150 km/h (93 mph)
Q max. 160 km/h (99 mph)
R max. 170 km/h (106 mph)
S max. 180 km/h (112 mph)
T max. 190 km/h (118 mph)
U max. 200 km/h (124 mph)
H max. 210 km/h (130 mph)
V max. 240 km/h (149 mph)
Z max. 240 km/h (149 mph)
W max. 270 km/h (168 mph)
Y max. 300 km/h (186 mph)
Some manufacturers use the letters "ZR" for
tyres with a maximum authorised speed
above 240 km/h (149 mph).

Winter service

Winter tyres*
In winter conditions winter tyres will consid-
erably improve the vehicle's handling. The
design of summer tyres (width, rubber com-
pound, tread pattern) gives less grip on ice
and snow. Winter tyres also improve the vehi-
cle braking performance, reducing the brak-
ing distance in winter weather. SEAT recom-
mend that winter tyres be fitted to the vehicle
at temperatures below +7 °C (+45 °F).
The performance of winter tyres is much re-
duced if the tyre tread is worn below 4 mm
(1/16 inch). The age of the tyre is another
factor affecting performance, regardless of
the depth of the tyre tread.
Please observe the following when using
winter tyres:
● Observe legal requirements in each coun-
try.
● Winter tyres must be fitted on all four
wheels.
● Only use winter tyres in wintery weather
conditions.
