Wheels and tires
Only check the tire inflation pressure when the
tires are cold. This means after driving no more
than 1.25 miles/2 km or when the vehicle has
been parked for at least 2 hours.
Vehicle features and options
This chapter describes all standard, country-
specific and optional features offered with the
series. It also describes features that are not
necessarily available in your car, e. g., due to
the selected options or country versions. This
also applies to safety-related functions and
systems. The respectively applicable country
provisions must be observed when using the
respective features and systems.
The displays of inflation devices may under-
read by up to 1.45 psi/0.1 bar.
For Flat Tire Monitor: after correcting the tire
inflation pressure, reinitialize the Flat Tire
Monitor.
For Tire Pressure Monitor: after correcting the
tire inflation pressure, reset the Tire Pressure
Monitor.

Safety information
The tire characteristics and tire inflation pres‐
sure influence the following:
The tire inflation pressure table, refer to
page 199, contains all tire inflation pressure
specifications for the specified tire sizes at the
ambient temperature. Tire inflation pressure
specifications apply to approved tire sizes and
recommended tire brands. This information
can be obtained from your service center.

▷
The service life of the tires.
Road safety.
Driving comfort.
To identify the correct tire inflation pressure,
please note the following:
Checking the tire inflation pressure
Check the tire inflation pressure regularly
▷
▷
Tire sizes of your vehicle.
Regularly check the tire inflation pres‐
sure, and correct it as needed: at least twice a
month and before a long trip. If you fail to ob‐
serve this precaution, you may be driving on
tires with incorrect tire pressures, a condition
that may not only compromise your vehicle's
driving stability, but also lead to tire damage
and the risk of an accident.◀
Maximum permitted driving speed.
Tire inflation pressures up to
100 mph/160 km/h
For speeds of up to 100 mph/160 km/h and for
optimum driving comfort, note the pressure
values in the tire inflation pressure table, refer
to page 199, and adjust as necessary.
Tires have a natural, consistent loss of tire in‐
flation pressure.
Tires heat up while driving, and the tire infla‐
tion pressure increases along with the tire's
temperature. The tire inflation pressure speci‐
fications relate to cold tires or tires with the
ambient temperature.

Mobility
Temperature grade for this tire
Treadwear
The treadwear grade is a comparative rating
based on the wear rate of the tire when tested
under controlled conditions on a specified gov‐
ernment test course. For example, a tire
graded 150 would wear one and one-half, 1 g,
times as well on the government course as a
tire graded 100. The relative performance of
tires depends upon the actual conditions of
their use, however, and may depart signifi‐
cantly from the norm due to variations in driv‐
ing habits, service practices and differences in
road characteristics and climate.
The temperature grade for this tire is es‐
tablished for a tire that is properly inflated and
not overloaded. Excessive speed, underinfla‐
tion, or excessive loading, either separately or
in combination, can cause heat buildup and
possible tire failure.
If necessary, have the vehicle towed.◀
RSC – Run-flat tires
Run-flat tires, refer to page 208, are labeled
with a circular symbol containing the letters
RSC marked on the sidewall.
Traction
M+S
The traction grades, from highest to lowest,
are AA, A, B, and C.
Winter and all-season tires with better cold
weather performance than summer tires.
Those grades represent the tire's ability to
stop on wet pavement as measured under
controlled conditions on specified government
test surfaces of asphalt and concrete. A tire
marked C may have poor traction performance.
Tire tread
Summer tires
Do not drive with a tire tread depth of less than
0.12 in/3 mm.
The traction grade assigned to this tire is
based on straight-ahead braking traction tests,
and does not include acceleration, cornering,
hydroplaning, or peak traction characteristics.
There is an increased danger of hydroplaning if
the tire tread depth is less than 0.12 in/3 mm.
Temperature
Winter tires
Do not drive with a tire tread depth of less than
0.16 in/4 mm.
The 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 a specified indoor laboratory test wheel.
Sustained high temperature can cause the ma‐
terial of the tire to degenerate and reduce tire
life, and excessive temperature can lead to
sudden tire failure. The grade C corresponds
to a level of performance which all passenger
car tires must meet under the Federal Motor
Vehicle Safety Standard No. 109. Grades Band
A represent higher levels of performance on
the laboratory test wheel than the minimum re‐
quired by law.
Below a tread depth of 0.16 in/4 mm, tires are
less suitable for winter operation.

Mobility
Wheels and tires
In case of tire damage
Minimum tread depth
If there are indications of tire damage, re‐
duce your speed immediately and have the
rims and tires checked right away; otherwise,
there is the increased risk of an accident.
Drive carefully to the nearest service center. If
necessary, have the vehicle towed or trans‐
ported there. Otherwise, tire damage can be‐
come life threatening for vehicle occupants
and also other traffic.◀
Wear indicators are distributed around the
tire's circumference and have the legally re‐
quired minimum height of 0.063 in/1.6 mm.
Repair of tire damage
For safety reasons, the manufacturer of
your vehicle recommends that you do not have
damaged tires repaired; they should be re‐
placed. Otherwise, damage can occur as a re‐
sult.◀
They are marked on the side of the tire with
TWI, Tread Wear Indicator.
Tire damage
Changing wheels and tires
General information
Inspect your tires often for damage, foreign
objects lodged in the tread, and tread wear.
Mounting
Information on mounting tires
Have mounting and balancing performed
only by a service center.
Hints
Driving over rough or damaged road surfaces,
as well as debris, curbs and other obstacles
can cause serious damage to wheels, tires and
suspension parts. This is more likely to occur
with low-profile tires, which provide less cush‐
ioning between the wheel and the road. Be
careful to avoid road hazards and reduce your
speed, especially if your vehicle is equipped
with low-profile tires.
If work is not carried out properly, there is a
danger of subsequent damage and related
safety hazards.◀
Wheel and tire combination
You can ask the service center about the right
wheel/tire combination and wheel rim versions
for the vehicle.
Indications of tire damage or other vehicle de‐
fects:
Incorrect wheel and tire combinations impair
the function of a variety of systems such as
ABS or DSC.
▷
▷
Unusual vibrations while driving.
Unusual handling such as a strong ten‐
dency to pull to the left or right.
To maintain good handling and vehicle re‐
sponse, use only tires with a single tread con‐
figuration from a single manufacturer.
Damage can, e. g., be caused by driving over
curbs, road damage, or similar things.
Following tire damage, have the original wheel
and tire combination remounted on the vehicle
as soon as possible.

Approved wheels and tires
Retreaded tires
You should only use wheels and tires
that have been approved by the vehicle manu‐
facturer for your vehicle type; otherwise, e.g.,
despite having the same official size ratings,
variations can lead to chassis contact and with
it, the risk of severe accidents
Possibly substantial variations in the de‐
sign and age of the tire casing structures can
limit service life and have a negative impact on
road safety.◀
Winter tires
The manufacturer of your vehicle cannot eval‐
uate non-approved wheels and tires to deter‐
mine if they are suited for use, and therefore
cannot guarantee the operating safety of the
vehicle.◀
Winter tires are recommended for operating on
winter roads.
Although so-called all-season M+S tires pro‐
vide better winter traction than summer tires,
they do not provide the same level of perform‐
ance as winter tires.
Recommended tire brands
Maximum speed of winter tires
If the maximum speed of the vehicle is higher
than the permissible speed for the winter tires,
then a respective symbol is displayed in your
field of vision. You can obtain this sign from the
tire specialist or from your service center.
Maximum speed for winter tires
Do not exceed the maximum speed for
the respective winter tires; otherwise, tire dam‐
age and accidents can occur.◀
For each tire size, the manufacturer of your ve‐
hicle recommends certain tire brands. These
can be identified by a star on the tire sidewall.
Run-flat tires
With proper use, these tires meet the highest
standards for safety and handling.
If you are already using run-flat tires, for your
own safety you should replace them only with
the same kind. No spare tire is available in the
case of a flat tire. Your service center will be
glad to advise you.
New tires
Tire traction is not optimal due to manufactur‐
ing circumstances when tires are brand-new;
they achieve their full traction potential after a
break-in time.
Rotating wheels between axles
Different wear patterns can occur on the front
and rear axles depending on individual driving
conditions. The tires can be rotated between
the axles to achieve even wear. Your service
center will be glad to advise you. After rotating,
check the tire pressure and correct if needed.
Drive conservatively for the first
200 miles/300 km.
Retreaded tires
The manufacturer of your vehicle does not rec‐
ommend the use of retreaded tires.
Rotating the tires is not permissible on vehi‐
cles with different tire sizes or rim sizes on the
front and rear axles.

inside.
Storage
Store wheels and tires in a cool, dry place with
as little exposure to light as possible.
The compressor can be used to check the tire
inflation pressure.
Always protect tires against all contact with oil,
grease and fuels.
Hints
Do not exceed the maximum tire inflation pres‐
sure indicated on the side wall of the tire.
▷
▷
Follow the instructions on using the Mobi‐
lity System found on the compressor and

▷
The use of a sealant can damage the TPM
wheel electronics. In this case, have the
electronics checked at the next opportu‐
nity and have them replaced if needed.

areas, since breathing in exhaust fumes may
lead to loss of consciousness and death. The
exhaust gases contain carbon monoxide, an
odorless and colorless but highly toxic gas.◀
Follow the instructions for continued driving
with a flat tire.
Storage
Changing run-flat tires
The Mobility System is located under the
cargo floor panel.
For your own safety, only use run-flat tires. No
spare tire is available in the case of a flat tire.
Your service center will be glad to advise you.
Mobility System
The concept
With the Mobility System, minor tire damage
can be sealed quickly to enable continued
travel. To accomplish this, sealant is pumped

4. Insert the sealant container on the com‐
pressor housing in an upright position.
7. With the ignition turned on or the engine
running, reel on the compressor.
Switch off the compressor after 10 mi‐
nutes
5. Screw the filling hose of the sealant con‐
tainer onto the tire valve of the defective
wheel.
Do not allow the compressor to run longer than
10 minutes; otherwise, the device will overheat
and may be damaged.◀
Let the compressor run for approx. 3 to 8 mi‐
nutes to fill the tire with sealant and achieve a
tire inflation pressure of approx. 2.5 bar.
While the tire is being filled with sealant, the
tire inflation pressure may sporadically reach
approx. 5 bar. Do not reel off the compressor at
this point.
6. With the compressor switched off, insert
the plug into the power socket inside the
vehicle.
If a tire inflation pressure of 2 bar is not
reached:
1. Switch off the compressor.
2. Unscrew the filling hose from the wheel.
3. Drive 33 ft/10 m forward and back to dis‐
tribute the sealant in the tire.
4. Inflate the tire again using the compressor.
If a tire inflation pressure of 2 bar cannot be
reached, contact your service center.
Stowing the Mobility System
1. Unscrew the filling hose of the sealant con‐
tainer from the wheel.
2. Unscrew the connection hose of the com‐
pressor from the sealant container.
3. Connect the filling hose of the sealant con‐
tainer previously connected to the tire
valve with the available connector on the
sealant container.

This prevents leftover sealant from escap‐
ing from the container.
Snow chains
4. Wrap the empty sealant container in suita‐
ble material to avoid dirtying the cargo
area.
Fine-link snow chains
Only certain types of fine-link snow chains
have been tested by the manufacturer of the
vehicle, classified as road-safe and approved.
5. Stow the Mobility System back in the vehi‐
cle.
Information about the approved snow chains
are available from the service center.
Distributing the sealant
Immediately drive approx. 5 miles/10 km to en‐
sure that the sealant is evenly distributed in the
tire.
Use
Use only in pairs on the rear wheels, equipped
with the tires of the following size:
Do not exceed a speed of 50 mph/80 km/h.
▷
▷
▷
225/55 R 17.
245/45 R 18.
245/40 R 19.
If possible, do not drive at speeds less than
12 mph/20 km/h.
Follow the snow chain manufacturer's instruc‐
tions.
To correct the tire inflation pressure
1. Stop at a suitable location.
Make sure that the snow chains are always
sufficiently tight. Retighten as needed accord‐
ing to the chain manufacturer's instructions.
2. Screw the connection hose of the com‐
pressor directly onto the tire valve stem.
3. Insert the connector into the power socket
inside the vehicle.
Do not initialize the Flat Tire Monitor after
mounting snow chains, as doing so may result
in incorrect readings.
4. Correct the tire inflation pressure to
2.5 bar.
Do not initialize the Tire Pressure Monitor after
mounting snow chains, as doing so may result
in incorrect readings.
▷
Increase pressure: with the ignition
turned on or the engine running, reel
on the compressor.
When driving with snow chains, briefly activate
Dynamic Traction Control if needed.
▷
To reduce the pressure: press the but‐
ton on the compressor.
Maximum speed with snow chains
Do not exceed a speed of 30 mph/50 km/h
when using snow chains.
Continuing the trip
Do not exceed the maximum permissible
speed of 50 mph/80 km/h.
Reinitialize the Flat Tire Monitor.
Snow chain detection
The concept
When using snow chains, settings should be
made via the iDrive for the snow chains being
applied.
Reinitialize the Tire Pressure Monitor.
Replace the defective tire and the sealant con‐
tainer of the Mobility System as soon as possi‐
ble.
The snow chain detection system supports
you by automatically showing the detected
state on the Control Display.
