MOBILITY
Minimum tread depth
Safety information
Warning
Damaged tires can lose tire inflation pres-
sure, which can lead to loss of vehicle con-
trol. There is a risk of accident, injury, and
property damage. If tire damage is suspected
while driving, immediately reduce speed and
stop. Have wheels and tires checked. To do
so, drive carefully to an authorized service
center or another qualified service center or
repair shop. Have the vehicle towed or trans-
ported as needed. Do not repair damaged
tires, but have them replaced.
The tire manufacturer’s wear indicators are
distributed over the tire circumference. These
indicators have a height of min. 0.06 in/1.6 mm
and serve as an indicator for tire tread wear.
The positions of the wear indicators are
marked on the tire sidewall with TWI, Tread
Wear Indicator.
Warning
The wheels, tires and chassis components
can become damaged when driving over
curbs, road damage, or other obstacles.
Larger wheels have a smaller tire cross-sec-
tion. The smaller the tire cross-section, the
higher the risk of tire damage. There is a risk
of accident, injury, and property damage. If
possible, avoid driving over curbs, road dam-
age or other obstacles, or drive over them
slowly and carefully.
Tire damage
General information
Check your tires regularly for damage, foreign
objects lodged in the tread, and tread wear.
Indications of tire damage or another vehicle
malfunction:
▷
▷
▷
Unusual vibrations.
Unusual tire or running noises.
Exchanging wheels and
tires
Unusual vehicle handling such as a strong
tendency to pull to the left or right.
▷
Uneven wear pattern, e.g., increased wear
in the area of the tire shoulder.
Mounting and wheel balancing
Have the wheel mounted and balanced by an
authorized service center or another qualified
service center or repair shop.
Damage can be caused by the following situa-
tions, for instance:
▷
▷
▷
▷
▷
Driving over curbs.
Road damage.
Suitable wheels and tires
Tire pressure too low.
Vehicle overloading.
Incorrect tire storage.
General information
Only certain wheel/tire combinations are suit-
able depending on vehicle and equipment.

Wheels and tires
MOBILITY
The vehicle manufacturer determines wheel/
tire combinations on the basis of the following
criteria:
tire combination remounted on the vehicle as
soon as possible.
▷
▷
Tire size, e.g., tire width, aspect ratio.
Wheel size, e.g., rim diameter, offset.
Recommended tire brands
For more information on wheel/tire combina-
tions and special equipment, contact an au-
thorized service center or another qualified
service center or repair shop.
Safety information
Warning
Wheels and tires that are not suitable for
the vehicle can damage parts of the vehicle.
There is a risk of accident, injury, and prop-
erty damage. The vehicle manufacturer rec-
ommends that you use only wheels and tires
that have been recommended for the vehicle
type.
Tire types are developed for each vehicle and
optimized specifically for the individual require-
ments of that vehicle, e.g.:
▷
▷
▷
Vehicle handling.
Comfort.
Noise characteristics.
Specially developed tires are marked with
a star on the tire sidewall. After replacing
wheels and tires, the vehicle manufacturer rec-
ommends using star-marked tires again. The
vehicle manufacturer recommends that you
use tires of the same make and tread design.
Warning
Mounted steel wheels can cause technical
problems, for instance unexpected loosening
of the lug bolts and damage to the brake
disks. There is a risk of accident, injury,
and property damage. Do not mount steel
wheels.
New tires
Tire traction is not optimal due to manufactur-
ing circumstances when tires are brand new.
Drive conservatively for the first
200 miles/300 km.
Warning
Wheel/tire combinations that are not suitable
for the vehicle can affect vehicle handling
and a number of system functions, e.g.,the
Antilock Braking System or Dynamic Stability
Control. There is a risk of accident, injury, and
property damage. The manufacturer of the
vehicle recommends that you use wheels and
tires that have been recommended by the
vehicle manufacturer for the vehicle type. Fol-
lowing tire damage, have the original wheel/
Retreaded tires
Warning
Retreated tires can have different tire casing
structures. With advanced age the service life
can be limited. There is a risk of accident,
injury, and property damage. The manufac-

turer of the vehicle does not recommend the
use of retreaded tires.
As a rule, all-season tires do not perform the
same as winter tires.
Changing runflat tires
Maximum speed
When changing from runflat tires to standard
tires, it must be ensured that the vehicle con-
tains an emergency wheel or tire mobility kit.
For more information, contact an authorized
service center or another qualified service cen-
ter or repair shop.
Safety information
Warning
If the maximum permissible speed of your
mounted tires is exceeded, the tires may be
damaged. There is a risk of accident, injury,
and property damage. Do not exceed the
maximum permissible speed of the tires.
Wheel change between axles
Warning
A wheel change between the axles on vehi-
cles with different tire sizes or rim sizes on
the front and rear axles can cause damage
to the tires and the vehicle. There is a risk
of accident, injury, and property damage. Do
not rotate the tires between the axles on ve-
hicles with different tire sizes or rim sizes on
the front and rear axles.
Maximum speed of winter tires
If the maximum speed of the vehicle is higher
than the maximum permissible speed of the
winter tires, the maximum permissible speed
must be indicated with a sign placed in the
field of vision. The info label is available from
an authorized service center or another quali-
fied service center or repair shop.
Different abrasion patterns can occur on the
front and rear axles depending on individual
driving conditions. The tires can be rotated in
pairs between the axles to achieve even abra-
sion. For more information, contact an author-
ized service center or another qualified service
center or repair shop. After changing, check
the tire pressure and correct, if needed.
Winter tires
Storing tires
Tire pressure
Do not exceed the maximum tire inflation pres-
sure indicated on the tire sidewall.
Winter tires are recommended for operating on
winter roads.
Winter tires can be identified by the moun-
tain/snowflake icon and the letters M+S on the
tire sidewall.
Storage
▷
Store wheels and tires in a cool, dry and
dark place.
So-called all-season tires with M+S marking
but without mountain and snowflake icon have
better winter properties than summer tires.
▷
Always protect tires against all contact with
oil, grease, and solvents.

▷
Do not leave the tires in plastic bags.
Remove dirt from wheels or tires.
Identification
Runflat tires
Principle
Runflat tires permit continued driving under
limited conditions even in the event of a com-
plete tire pressure loss.
Runflat tires are labeled with a circular icon
containing the letters RSC marked on the tire
sidewall.
General information
The wheels consist of tires that are self-sup-
porting to a limited degree and may also in-
clude special rims.
Repairing a flat tire
The reinforcement of the sidewall allows the
tire to remain drivable to a limited degree in
the event of a tire pressure loss.
Safety precautions
Follow the instructions for continued driving
with a flat tire.
▷
Park the vehicle on solid and non-slip
ground at a safe distance from road traffic.
▷
▷
▷
Turn on the hazard warning system.
Set the parking brake.
Safety information
Turn the steering wheel until the front
wheels are in the straight-ahead position
and engage the steering wheel lock.
Warning
The vehicle handles differently when a runflat
tire has insufficient or no tire pressure; for
instance, reduced directional stability when
braking, braking distances are longer and the
self-steering properties will change. There is
a risk of accident, injury, and property dam-
age. Drive moderately and do not exceed a
speed of 50 mph/80 km/h.
▷
▷
As soon as permitted by the traffic flow,
have all vehicle occupants get out and
make sure that they remain outside the
hazardous area such as behind a guardrail.
If necessary, set up the hazard triangle or
hazard warning lights at an appropriate
distance.
Warning
Tire repair set
Vibrations or loud noises while driving can
indicate the final failure of a tire. Tire compo-
nents may come loose. There is a risk of ac-
cident, injury, and property damage. Reduce
your speed and stop. Do not continue driving.
Contact an authorized service center or an-
other qualified service center or repair shop.
Principle
The tire repair set is used to temporarily seal
minor tire damage so that it is possible to con-
tinue driving.
