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

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.

SPARE
WHEEL

The
spare wheel is located underneath the floor panel of the driver cab, where it rests on a hinged metal plate.
• To take out the spare wheel, remove
the bolt (curved arrow) from the holding bracket
with
wheel wrench,

WARNING
Keep hands and
arms
away
from
under-

body of vehicle.
• Stand in
front
of the vehicle and pull the

catch
hook (arrow) forward to let the metal
plate drop.
•
Pull
out the spare wheel. • When re-installing the spare wheel,

slide
spare wheel onto metal plate.
•
Give
the plate a hard upward push and

make
sure the catch hook is securely

engaged.

•
Replace
bolt and tighten firmly.

WARNING
Never
drive
the
vehicle
without
a
firmly

tightened
bolt
on the holding
bracket.
Should the catch
hook
disengage acci­

dentally,
you could lose
control
of the
car.

Check
the inflation pressure periodically to

keep
the
tire
ready for use.
WARNING

Under
no circumstances should you

store
the spare
wheel
unsecured in the
luggage
compartment.
This coulc
cause serious personal
injury
to pas­
sengers in the
vehicle
in case of a coll -

sion.

• Fully unscrew wheel nuts or bolts and

dace
them into the hub cap. Take the top
nut or bolt off last.
Place
the spare wheel against the wheel hub and slightly rotate
:he wheel until a bolt hole in the wheel is in ine
with
a threaded stud in the wheel hub.

Reinstall
nuts or bolts and tighten them

crosswise
by hand before jacking the car

down.

Step
7 • To
lower
the vehicle,
turn
the handle

counterclockwise.
Step
8
• Then go crosswise from one nut or bolt
to another tightening them firmly
with
the lug wrench.
• Correct
tightness
of the
wheel
nuts
is

important.

• Correctly tightened nuts or bolts should

have
a torque of 130 ft lb/180 Nm. This
tor­

que can be obtained
with
the lug wrench by any person of average strength. If in
doubt about the correct tightness of the
wheel nuts, have them checked
with
a
tor­

que wrench by your dealer or at service
station.
Step
9
• To install the hub cap, place it around
the lower part of the wheel center. With a

firm
blow of your hand on the upper part,
the hub cap will snap into place. Make sure it is firmly seated.

Step
10 • Fully lower the vehicle and remove
jack.
• Correct the air pressure of the
tire
you

have
just
put on. For correct
tire
inflation

pressures,
see the sticker on the
left
door-
jamb.
• Store the jack and tools under the
driver's seat.
• Store damaged
tire
in spare wheel
metal plate under
front
of vehicle.
• Engage lock for metal plate and firmly

secure
plate
with
bolt.
• Have
flat
tire
repaired and replaced
promptly.
