Minimum tread depth
Wear indicators are distributed around the tire's
circumference and have the legally required
minimum height of 0.063 in/1.6 mm.
They
are marked on the side of the tire with TWI,
Tread Wear Indicator.
Tire damage
General information
Inspect your tires often for damage, foreign ob‐
jects lodged in the tread, and tread wear.
Notes
Indications of tire damage or other vehicle de‐
fects:
▷ Unusual vibrations during driving.
▷ Unusual handling such as a strong tendency
to pull to the left or right.
In case of tire damage
If there are indications of tire damage, re‐
duce your speed immediately and have the
wheels

and tires checked right away; otherwise,
there is the increased risk of an accident.
Drive carefully to the next service center or tire
shop.
If necessary, have the vehicle towed.◀
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.◀ Changing wheels and tires
Mounting
Information on mounting tires
Have mounting and balancing performed
only by a service center or tire specialist.
If this work is not carried out properly, there is
the danger of subsequent damage and related
safety hazards.◀
Wheel and tire combination
Information on the correct wheel-tire combina‐
tion

and rim versions for your vehicle can be ob‐
tained from your service center.
Incorrect wheel and tire combinations impair the
function of a variety of systems such as ABS or
DSC.
To maintain good handling and vehicle re‐
sponse, use only tires with a single tread con‐
figuration from a single manufacturer.
Following tire damage, have the original wheel
and tire combination remounted on the vehicle
as soon as possible.
Approved wheels and tires
The manufacturer of your vehicle recom‐
mends that you use only wheels and tires that
have been approved for your particular vehicle
model.
For example, despite having the same official
size ratings, variations can lead to body contact
and with it, the risk of severe accidents.
The manufacturer of your vehicle cannot evalu‐
ate non-approved wheels and tires to determine
if they are suited for use, and therefore cannot
ensure the operating safety of the vehicle if they
are mounted.◀ Seite 251

Recommended tire brands
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.
With proper use, these tires meet the highest
standards for safety and handling.
New tires
Due to technical factors associated with their
manufacture,
tires do not achieve their full trac‐
tion potential until after an initial breaking-in pe‐
riod.
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.
Retreaded tires
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 recommends
winter tires for winter roads or at temperatures
below +45 ℉/+7 ℃.
Although so-called all-season M+S tires do pro‐
vide better winter traction than summer tires,
they do not provide the same level of perform‐
ance 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 display a corresponding sign in the field of
vision.

You can obtain this sign from the tire spe‐
cialist or from your service center.
Maximum speed for winter tires
Do not exceed the maximum speed for the
winter tires; otherwise, tire damage and acci‐
dents can occur.◀
Run-flat tires
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.
Rotating wheels between axles
The manufacturer of your vehicle advises
against swapping wheels between the front and
rear axles.
This can impair the handling characteristics.
Storage
Store wheels and tires in a cool, dry place with
as little exposure to light as possible.
Always protect tires against all contact with oil,
grease and fuels.
Do not exceed the maximum tire inflation pres‐
sure indicated on the side wall of the tire.

252 Online Edition for Part no. 01 40 2 606 469 - 03 11 490
Wheels and tires

The wheels are composed of special rims and
tires that are self-supporting, to a limited de‐
gree.
The
support of the sidewall allows the tire to re‐
main drivable to a restricted degree in the event
of a pressure loss.
Continued driving with a damaged tire., refer to
page 90
Changing run-flat tires
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.
Snow chains
Fine-link snow chains
Only certain types of fine-link snow chains have
been tested by the manufacturer of your vehicle,
classified as road-safe and recommended.
Consult your service center for more informa‐
tion.
Use
Use only in pairs on the rear wheels, equipped
with the tires of the following size:
▷ 225/55 R 17.
▷ 245/45 R 18.
Follow the chain manufacturer's instructions.
Make
sure that the snow chains are always suf‐
ficiently tight. Retighten as needed according to
the chain manufacturer's instructions.
Do not initialize the Tire Pressure Monitor after
mounting snow chains, as doing so may result
in incorrect readings.
When driving with snow chains, briefly activate
Dynamic Traction Control if necessary.
Maximum speed with snow chains
Do not exceed a speed of 30 mph/50 km/h when
using snow chains. Snow chain detection*
The concept
When using snow chains, you should set
whether you are driving with or without snow
chains via the iDrive.
The

snow chain detection system supports you
by automatically showing the detected state on
the Control Display.
When snow chains are in use, the rear axle steer‐
ing of the Integral Active Steering* is deacti‐
vated automatically.
At speeds above the maximum allowable speed
with snow chains of 30 mph/50 km/h, the rear
axle steering is activated again automatically.
Activating the status
1. "Settings"
2. "Tire chains"
3. "Tire chains installed"
Automatic detection
If functioning properly:
▷ Snow chains are mounted. The setting is not
activated .
After you drive a short distance, a Check
Control message is shown and the state is
activated automatically.
Confirm the automatic activation.
▷ Snow chains are not mounted. The setting
is activated .
At speeds above 30 mph/50 km/h, a Check
Control message is displayed. Deactivate
the status manually.
If not functioning properly:
▷ Snow chains are mounted. The setting is not
activated .
A Check Control message is not displayed.
The

automatic detection system is malfunc‐
tioning. Activate the status manually.
