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
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 thecase 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.
Run-flat tires
Label
RSC label on the tire sidewall.
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 99.
Continued driving with a damaged tire, refer to

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 deactivated
automatically.
At speeds above the maximum permitted speed
with snow chains of 30 mph/50 km/h, the rear
axle steering is activated again automatically.
