with
regular use
a
wheel can
get out of
balance,
and should thereiore
be
balanced
lrom time

Unbalanced
wheels may
affect car handling
and

tife.
When
balancing light
alloy wheels, use
only
adhesive balancing
weights
supplied
through the
Porsche parts service.
Wheels
lf

to
use other than
original
equipment wheels,
be

that they
con-
form to Porsche specifications for your mod-

Removing and sloring
tires
The driving
direction
and
lhe posilion
rela-
live
to
the
hub
should
be
clearly marked on
all tires before removing them ,or storage,
to make sure they are mounled and run
in
lhe
same
direction as befole.
Store
tires
in a cool
and
dry place.
Tires
without rims
uprightl Avoid contact with
oil,
grease
or
gasoline.
when remounting, put
tires
with the most tread depth at the front
(possible only with tires and
rims
of
same
size
on front and
rear
axlei).
Snow
tires
For
a
better grip on
snow
and ice use radial
M+S tires
or
snow tires with studs.
Check
with your local
lvlotor
Vehicle Bureau for
possible restrictions.
Radial
ply
L4+S
tires should
be
inllated with
the
same
cold
tire
inflation pressures
re-
quired for the regular radial ply
tires. Howev-
er,
do not exceed the maximum
tire inflation
presslrre listed on the tire sidewall.
Snow
tires should
have
the
same
load
capacity
as original
equipment tires
and
should be mounted on all
four wheels. Snow
tires
with studs should be run at
moderate
speeds
when new in order
to give
lhe studs
time
to settle.
