SIDEWALL 1 PLY
RAYON
Data on the tyre carcass components:
1 layer of rayon
(artificial
silk).
TREAD 4 PLIES
Data on the tread surface components:
1 RAYON + 2 STEEL
+ 1 NYLON
In this example there are 4 layers under the tread surface:
1 layer of rayon
(artificial
silk), 2 layers of steel belt and 1 lay-
er of nylon.
The tyre label is located on both sides. Cer-
tain labels may only be found on one side
of the tyre, e.g. tyre
identification
number
and manufacturing date.
Any further numbers and letters are inter-
nal codes used by the tyre manufacturer or
country-specific
denotations.
Low-profile tyres
Low-profile
tyres have a wider tread sur-
face, larger rim diameter and lower side-
walls than conventional wheel/tyre combi-
nations

page 335.
Low-profile
tyres can
improve the vehicle's handling and preci-
sion. They may however result in a less
comfortable ride on uneven road surfaces
and tracks.
Tyres with directional tread pattern
An arrow on the tyre sidewall indicates the
direction of rotation on tyres with direction-
al tread. The direction of rotation must be
observed in all cases. This makes sure they
run as smoothly as possible.
If, however, the tyre is
fitted
in the opposite
direction to the tread pattern, you must
take more care when driving as the tyre is
now no longer being used according to its
designation. The tyres must be replaced as
quickly as possible or be
fitted
with the
tread in the correct direction.
Asymmetrical tyres
Asymmetrical tyres take into account the
differing
behaviour of the inner and outer
areas of the tread pattern. The sidewalls of
asymmetrical tyres are marked to indicate
"inside" or "outside". Maintain the correct
tyre positioning on the wheel rim.
Mobility tyres
The word “Seal” is on the outer wall of the
tyre if your vehicle is
fitted
with mobility
tyres.
A sealant applied to the inner side of the
tread encloses foreign bodies penetrating
the mobility tyre and seals the tyre tempo-
rarily.
Tyre load
The load capacity index indicates how
many kilograms can be loaded onto an in-
dividual tyre (tyre load).
