Tires
Tread wear indicators (TWJ) are
required by law. The limits defined
there are absolute minimum and indi­
cated on the tire by wear indicators.
These indicators - little humps which
are embeded equally at six sections of
the tire circumference in the bottom of
the tread - become visible as cross
stripes on the tire running surface once
the wear limit is reached.
Warning!
Do not allow your tires to wear down
too far. With less than 3 mm (V» in)
of tread, the antiskid properties on a
wet road fall off sharply.
Depending upon the weather and/or
road surface (conditions), the trac­
tion varies widely.
Specified tire pressure must be main­
tained. This applies particularly if the
tires are subjected to high loads (e.g.
high speeds, heavy loads, high
ambient temperatures).

Aquaplaning
Depending on the depth of the water
layer on the road, aquaplaning may
occur, even at low speeds and with
new tires. Avoid track grooves in the
road and apply brakes cautiously in the
rain.
Tire friction
The safe speed on a wet or icy road is
always lower than on a dry road.
You should pay particular attention to
the condition of the road as soon as the
prevailing temperatures fall close to the
freezing point.
Warning!
If ice has formed on the road, tire
traction will be substantially
reduced. Under such weather condi­
tions, drive, steer and brake with
extreme caution.
We recommend M + S radial-ply tires
for the cold season. On packed snow,
they can reduce your stopping distance
as compared with summer tires. Stop­
ping distance, however, is still consid­
erably greater than when the road is
wet or dry.
