TIRES/WHEELS
New tires

New
tires
do not
possess
maximum trac­

tion
and
should
be
driven
at
moderate
speeds
and
with
caution
for the
first
100
miles (160 kilometers).
Tire traction

WARNING
When driving on wet or slushy roads, a wedge of
water
may build up
between

the tires and the road. This phenome­ non is known as aquaplaning or hydro­
planing and may cause
partial
or
com­

plete
loss
of traction, vehicle control or
stopping ability. Always reduce speed

on
wet roads.
Tire service life
The service
life
of
your tires depends
for

the most
part
on the following factors:

Tire pressures
WARNING
•
Incorrect
tire
pressures cause

increased
tire
wear
and adversely

affect
road holding of the vehicle, lead­ ing to
loss
of control and personal
injury.

•
Incorrect
tire
pressures can also
lead to
sudden
deflation, resulting
in
an
accident and personal injury.

Check
your
tire
pressures twice
a
month,
and especially before taking
a
long
trip.
Be

sure
not to
forget
to
check
the
spare tire.
Always check
tire
pressures when the tires are cold. When
the
tires
are
warm,
the
pressure
will
be
higher.
Do not
reduce
the

pressure
of
warm tires.

Use
an accurate
tire
pressure gauge when
checking inflation pressures.
Do not

exceed
the
maximum
tire
inflation pres­ sure listed
on the
tire
sidewalk Cold
tire

inflation pressure means: when
a
vehicle

has
been standing
for at
least
3
hours
or

driven
for
less than 1 mile.
Always include the spare
tire
during
a
pres­ sure check.

Driving habits
Fast
cornering, heavy acceleration
and

hard braking all increase
tire
wear.

Wheel balancing

The
front
wheels
on new
vehicles
are
balanced.
When driving, however, various
conditions can cause
a
wheel
to
become
unbalanced.
This may
be
noticed as vibra­
tions
in the
steering.

Since
tire
imbalance
can
cause wear
or

the steering, suspension
and
tires,
you

should have your wheels rebalanced.
A

wheel should always
be
balanced
if a
nev,

tire
has
been mounted
or a
tire
was re­
paired.

VEHICLE CARE

Tire
care
Inspect your tires at least every 2,000
miles (3,000 km) for wear and damage.

WARNING
• Avoid
damaging
tires
and
wheel

rims.
If you
must
drive
over
a
curb
or

other
obstacle,
drive
slowly
and at an
angle.
Frequently
check
tires
for un­

even
wear
and
damage.

•
Remove
imbedded
material.

•
Replace
worn
or
damaged
tires

immediately.

•
Replace
missing
valve
dust
caps.
• Keep oil,
fuel,
brake
fluid,
etc.
away

from
tires.

• Keep
tires
inflated
correctly.

• Mark tires before removing them.
Remount tires on the same vehicle side

because
the rotation direction should stay
the same.
• Store removed tires in a
cool,
dry and
preferably dark place. Tires which are not
on wheels should be stored standing up.

Tires
age even if they are not being
used.

Tires
which are older than 6 years should only be used cautiously in an emergency.
Wheels
and
tire
replacement

Wheels
and tires approved by the manu­
facturer have been specially matched to
your vehicle and contribute largely to the road-holding and driving characteristics of
the vehicle.
• Fitting and repairing tires requires
expert knowledge and special tools. This
work should only be performed by a
spe­
cialist.
• For safety reasons, tires should be

replaced
in pairs and not individually. The
tires
with
the deepest tread should always be mounted on the
front
wheels.
• In the interest of maximum safety and
best all-around vehicle handling, always
buy replacement radial tires
that
have the

same
specifications
with
regard to
tire

size,
design, load carrying capacity, tread pattern, tread depth etc. This also applies
to Volkswagen recommended alternate replacement tires.
• Never mount used tires if you are not
sure of their previous history.
• Whenever replacing a tubeless tire,
always install a new valve stem. Tire repair
should only be performed by a specialist.
WARNING

•
Never
mix
tires
of
different
design
such as
steel
belted
radials
with
radial
bias
belted
or
bias
ply
tires
etc.
Mixing

tire
types
will
adversely
affect
road
holding
and can
lead
to loss of
vehicle

control
and
personal
injury.

• New
tires
do not possess
maximum

traction.
They
tend
to be
slippery.
Break
new
tires
in by
driving
cautiously

at
moderate
speed for the
first
100

miles
(160
kilometers).

Applies
additionally
to the Syncro:

All
four wheels on the vehicle must always have tires of the same
size,
construction
and tread type so
that
the viscous coupling

does
not abnormally activate the
front

wheel drive. Different tires on the
front
or rear wheels exert additional stress on the
drive
train
components, causing increa­

sed
tire
wear and impair vehicle control.

VEHICLE CARE

WARNING

The
traction
grade
is based on
brak­
ing
(straightahead)
traction
tests
and
does not
include
cornering
(turning)

traction.

Temperature
A, B, C
The temperature grades A (the highest), B and C, represent the tire's resistance to the
generation of heat. Sustained high tem­peratures can reduce
tire
life, and lead to
sudden
tire
failure. Grade C corresponds
to a performance which all passenger car
tires must meet under the Federal Motor

Vehicle
Safety Standard No. 109.
Grades
B
and A represent higher levels than the minimum required by law.

WARNING

The
temperature
grade
for
this
tire
is
established
for a
tire
that
is
properly
inflated
and not
overloaded.
Excessive
speed,
underinflation,
or excessive loading,
either
separately
or in combi­

nation,
can cause
heat
buildup,
possi­
ble
tire
failure,
loss of
control
and
per­

sonal
injury.
Snow
tires

The tires for your vehicle were selected for optimal performance under normal driving
conditions.

For
winter driving, the roadability of your
vehicle can be improved by installing all
season
tires or radial snow tires (M + S)

with
or
without
studs1).
That applies also to the Syncro - see page 78.
When installing snow tires, please note the following:
• Only radial ply snow tires must be

installed.
Ask your Volkswagen dealer for
the recommended
tire
size.

• Snow tires should be mounted on all
four wheels.
• The
tire
pressures for snow tires are the

same
as for summer tires. However, do not

exceed
the maximum
tire
pressure listed
on the sidewalk
• Snow tires should have the same load
capacity as original equipment tires and
should be mounted on all four wheels. • Snow tires do not
fulfill
their purpose, if
the tread depth is
less
than
%2
in (4 mm).

WARNING
•
Tires
with
badly
worn
treads
and
studs are
very
dangerous.
Make
sure

they
are
replaced
immediately.

•
Never
mix
tires
of
different
design
such as
steel
belted
radials
with
radial
bias
belted
or
bias
ply
tires
etc.
Mixing

tire
types
will
adversely
affect
road
holding
and can
lead
to loss of
vehicle

control
and
personal
injury.

• Snow tires
with
studs should be run at
moderate speeds when new in order to
give the studs time to settle.

Do
not drive a vehicle equipped
with
snow
tires at prolonged high
speed.
Snow tires
do not have the same degree of traction on
dry, wet or snowfree roads as a normal tire. Furthermore, snow tires wear rapidly
under these conditions.
• Where snow tires are compulsory on
certain roads, this also applies to vehicles

with
all-wheel-drive.
118 1)
Check
with
your local Motor Vehicle Bureau for

possible
restrictions.

Notes

Spark
plugs are replaced during the Volks­
wagen scheduled Maintenance service. If
you replace the spark plugs between the

Volkswagen
Maintenance services, the
following should be noted: • Engine, spark plugs and the ignition
system are matched. To avoid faulty opera­

tion
or engine damage, use only Original

Volkswagen
spark plugs. It is especially important to note the number of electrodes
and heat value. • Since spark plug specifications may

change
for technical reasons during a cur­
rent
model year, we recommend
that
you
obtain your spark plugs from a Volks­
wagen dealer who has the latest informa­
tion.
