be
necessary,
they
musl be mounted

Check
with
local authorities
for
possible
re-
strictions.
Use
only
Porsche-approved
snow
chains
with
line
pitch
links, so
that
enough
space
remains
between
the
chains and
the
inside
of
the wheel arches.
Drive

New
Tire ldentirlcations
The
European
tire
manufacturers
have
changed
their
tire
identification
system
for
SR
and HR-tires pertaining
to
maximum per-
missible
speed
and maximum
toad carrying
capacity
for
belted tires. The
following
is an
example only.
During
the
transition period some
tires
mighl show both old and
new
identification
codes,
such
as:
215/60
SR 15
M+S
88
e.
In
this
instance,
the
new codes apply.
The
idenllfication
codes
tor
ZR
tites
remain
unchanged;
Ior
example:
205/55
ZR
16.
(Z
:
maximum permissible
speed
for
radial
tires, i.e.
over
149
mph
or
240 km/h).
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.
Snow tires do
nol fulfill
their purpose if the
tread depth
is
less
than
5132
in.
