Wheels and Tires.
A car's tires and wheels are
components
vital
to
motoring safety. The tubeless radial tires and
wheels supplied
with
the Saab 900 have been
specially selected for the
different
models and
are major
factors
contributing
to
its
exceptional
roadholdlng and stability.
Consult
your Saab
dealer before
fitting
nonstandard wheels or
tires.

applications

Specifications.
Tire Pressures
Check tire pressures regularly.
Adjust tire pressures to
suit
the load and speed
normal for the car.
See
tire
pressure
table
, Spec·
Iflcations
Section.
The recommended pres·
sures are for tires when cold. Never reduce the
pressure when the
tire
Is warm. If
tire
pressures
are checked when the
tires
are warm then the
pressure should
only
be Increased. Incorrect
tires. See

and wheel
applications
chart,
Section
liE,
Specifications.
NOTE!
Do
not
forget
to
adjust
the
tire
pressures
If
the
load
or
speed Is radically
altered. Add 1.5 psi
to
light
load
value If
the
car
has
air
conditioning
.
Wear Indicators
The
tires
are
fitted
with
wear
indlcators-a
transverse strip (approx. 12mm, 0.5 in., wide)
without
a pattern appears when 1.6 mm (0.06
In
.)
of
the tread remains. When
this
strip Is visible
the tire should be replaced.
Winter tires
The 185/65 SR15 standard steel·beited radial ply
tires,
if
they have at least
half
their
original
tread depth, are
also
suitable
for
winter
use in
moderate
climates
where snow and ice are not
too
severe. The 900 Turbo
3·door
model
is
equipped
with
wide profile tires
which
have
been developed to give the greatest possible
roadholding and
stability
under both wet and
dry
driving
conditions
with
the result that the
tread
compounds
and designs are not
suitable
for use on ice and snow.
We
therefore recom·
mend
winter
tires or
"all
weather"
tires for
this
model when driving on
snow
or ice.
(See
Section
10,
Winter
Driving.)
Tire Rotation
The front·wheel drive causes the front tires to
wear more than the rear tires.
If
It Is desired to
have the tires wear evenly, they should be
ex·
changed
front
to rear
after
a
certain
period
of
driving so
that
the least worn tires are at the
front. By
switching
the tires in
this
manner, the
service
life
of
all four tires will remain approxl·
mately equal. Make sure that the tires are al·
ways rotated
In
the same
direction-the
left
front wheel should
thus
change place
with
the
left
rear wheel. Do not change radial tires from
side to side.
WHEEL CHANGING
The tool kit,
jack
and a
compact
type spare
wheel are stored under a cover in the
floor
of
the
rear part
of
the luggage
compartment.
To
jack
up the car,
install
the
jack
In
one
of
the
jacking
points
(front or rear) located underneath
the
sill
beams (see illustration).
If a garage
jack
is used, the
lifting
heads must
be
located under the reinforced
parts
of
the
underbody.
WARNING! Never crawl
under
the
car
when
It
Is Jacked up.
