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 con‐
tact and with it, the risk of severe accidents.
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 ensure the operating safety of the vehi‐
cle if they are mounted.◀
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
traction potential until after an initial breaking-
in period.
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
provide better winter traction than summer tires, they do not provide the same level of per‐
formance 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
specialist or from your service center.
Maximum speed for winter tires
Do not exceed the maximum speed for
the winter tires; otherwise, tire damage and ac‐
cidents 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 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 switching wheels between the front
and rear axles.
This can impair the handling characteristics.
StorageStore wheels and tires in a cool, dry place with
as little exposure to light as possible.Seite 193Wheels and tiresMobility193

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
remain drivable to a restricted degree in the
event of a pressure loss.
Continued driving with a damaged tire, refer to
page 104.
Continued driving with a damaged tire, refer to
page 101.
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 recom‐
mended.
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:▷205/60 R 16.▷225/55 R 16.▷225/50 R 17.▷225/45 R 18.
Follow the chain manufacturer's instructions.
Make sure that the snow chains are always
sufficiently tight. Retighten as needed accord‐
ing to the chain manufacturer's instructions.
Do not initialize the Flat Tire Monitor after
mounting snow chains, as doing so may result
in incorrect readings.
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.
