TemperatureThe
temperature
grades
are
A,
the
highest,
B,
and
C,
representing
the
tire's
resistance
to
the
generation
of
heat
and
its
ability
to
dissipate
heat when
tested
under
controlled
conditions
on
aspecified
indoor
laboratory
test
wheel.
Sustained
high
temperature
can
cause
the
material
of
the
tire
to
degenerate
and
reduce
tire
life,
and
exces#j sive
temperature
can
lead
to
sudden
tire
failure.
The
grade
C
corresponds
to
a
level
of
perform#j

Tire
damage
General
information Inspect
your
tires
regularly
for
damage,
foreign
objects
lodged
in
the
tread,
and
tread
wear.
Driving
over
rough
or
damaged
road
surfaces,
as
well
as
debris,
curbs
and
other
obstacles
can
cause
serious
damage
to
wheels,
tires
and
sus#j
pension
parts.
This
is
more
likely
to
occur
with low-profile
tires,
which
provide
less
cushioning
between
the
wheel
and
the
road.
Be
careful
to
avoid
road
hazards
and
reduce
your
speed,
es#j
pecially
if
your
vehicle
is
equipped
with
low-pro#j file
tires.

Safety
information
Warning
Damaged
tires
can
lose
tire
inflation
pressure,
which
can
lead
to
loss
of
vehicle
control.
There is
a
risk
of
accident.
If
tire
damage
is
suspected
while
driving,
immediately
reduce
speed
and
stop.
Have
wheels
and
tires
checked.
For
this
purpose,
drive
carefully
to
the
nearest

as
needed.
Do
not
repair
damaged

Warning
Tires
can
become
damaged
by
driving
over
ob#j
stacles,
e.g.,
curbs
or
road
damage,
at
high
speed.
Larger
wheels
have
a
smaller
tire
cross- section.
The
smaller
the
tire
cross-section,
the
higher
the
risk
of
tire
damage.
There
may
be
a
risk
of
accident
and
risk
of
damage
to
property.
If
possible,
avoid
driving
over
objects
or
road
conditions
that
may
damage
tires,
or
drive
over
them
slowly
and
carefully.

Warning
Mounted
steel
wheels
can
cause
technical problems,
for
instance
unexpected
loosening
ofthe
lug
bolts
and
damage
to
the
brake
discs.
There
is
a
risk
of
accident.
Do
not
mount
steel
wheels.
Warning
Incorrect
wheel/tire
combinations
will
impair
the vehicle's
handling
characteristics
and
a
variety
of
system
functions,
such
as
the
Antilock
Brak#j
ing
System
(ABS)
or
Dynamic
Stability
Control.
There
is
a
risk
of
accident.
To
maintain
good
handling
and
vehicle
response,
use
only
tires
with
a
single
tread
configuration
from
a
single
manufacturer.
The
manufacturer
of
the
vehicle
recommends
that
you
use
wheels
and
tires
that
have
been
recommended
by
the
vehicle
manu#j
facturer
for
your
vehicle
type.
Following
tire
damage,
have
the
original
wheel/tire
combina#j
tion
remounted
on
the
vehicle
as
soon
as
pos#j
sible.
Recommended
tire
brands
For
each
tire
size,
the
manufacturer
of
the
vehi#j cle
recommends
certain
tire
brands.
The
tire
brands
can
be
identified
by
a
star
on
the
tire
sidewall.
New
tires Tire
traction
is
not
optimal
due
to
production-re#jlated
circumstances
when
tires
are
brand-new.
Drive
conservatively
for
the
first
200
miles/300
km.
Retreaded
tires
Warning
Retreaded
tires
can
have
different
tire
casing structures.
With
advanced
age
the
service
life
can
be
limited.
There
is
a
risk
of
an
accident.
The
manufacturer
of
your
vehicle
does
not

the
use
of

Winter
tires General
information Winter
tires
are
recommended
for
operating
on
winter
roads.
Although
so-called
all-season
tires
with
M+S identification
provide
better
winter
traction
than
summer
tires,
they
usually
do
not
provide
the
same
level
of
performance
as
winter
tires.
Maximum
speed
of
winter
tires
If
the
maximum
speed
of
the
vehicle
is
higher
than
the
permissible
speed
for
the
winter
tires,
then
attach
a
label
showing
the
permissible
maxi#j mum
speed
in
the
field
of
vision.
The
label
is
available
from
a
dealer's
service
center
or
an#j other
qualified
service
center
or
repair
shop.
With
winter
tires
mounted,
observe
and
do
not
exceed
the
permissible
maximum
speed.
Changing
runflat
tires When
changing
from
run-flat
tires
to
standard
tires,
it
must
be
ensured
that
the
vehicle
contains
a
compact
spare
tire
("donut")
or
tire
mobility
kit.
Further
information
is
available
from
a

Warning
Rotating
tires
between
the
axles
on
vehicles
with
different
tire
sizes
or

sizes
on
the
front
and
rear
axles
can
cause

Principle
Run-flat
tires
permit
continued

under
re#j
stricted
conditions
even
in
the
event
of
a

General
information The
wheels
consist
of
tires
that
are
self-support#j
ing,
to
a
limited
degree,
and
possibly
special
rims.
The
reinforcement
of
the
sidewall
allows
the
tire
to
remain
drivable
to
a
restricted
degree
in
the event
of
a
tire
pressure
loss.
Follow
the
instructions
for
continued
driving
witha
flat

Safety
information
Warning
The
