Safety information
The tire characteristics and tire inflation pres‐
sure influence the following:
For speeds of up to 100 mph/160 km/h and for
optimum driving comfort, note the pressure val‐
ues in the tire inflation pressure table, refer to
page 244, and adjust as necessary.

Road safety.
Driving comfort.
Checking the pressure
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. When the tires
are warm, the tire inflation pressure is higher.
These pressure values can also be found on the
tire inflation pressure label on the driver's door
pillar.
Check the tire inflation pressure regularly
Regularly check the tire inflation pressure
and correct it as needed: at least twice a month
and before a long trip. If you fail to observe this
precaution, you may be driving on tires with in‐
correct 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 permissible speed
Do not exceed 100 mph/160 km/h; other‐
wise, tire damage and accidents may result.◀

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 significantly from the norm due
to variations in driving habits, service practices
and differences in road characteristics and cli‐
mate.

Traction
The traction grades, from highest to lowest, are
AA, A, B, and C.
248
Online Edition for Part no. 01 40 2 606 497 - 03 11 490
Those grades represent the tire's ability to stop
on wet pavement as measured under controlled
conditions on specified government test surfa‐
ces 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, hydro‐
planing, or peak traction characteristics.
There is an increased danger of hydroplaning if
the tread depth is less than 0.12 in/3 mm.
Winter tires
Do not drive with a tire tread depth of less than
0.16 in/4 mm.
Temperature
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. Sus‐
tained high temperature can cause the material
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 required by law.
Below a tread depth of 0.16 in/4 mm, tires are
less suitable for winter operation.
Minimum tread depth
Temperature grade for this tire
Wear indicators are distributed around the tire's
circumference and have the legally required
minimum height of 0.063 in/1.6 mm.
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 pos‐
sible tire failure.
They are marked on the side of the tire with TWI,
Tread Wear Indicator.
If necessary, have the vehicle towed.◀
Tire damage
RSC – Run-flat tires
General information
Run-flat tires, refer to page 251, are labeled with
a circular symbol containing the letters RSC
marked on the sidewall.
Inspect your tires often for damage, foreign ob‐
jects lodged in the tread, and tread wear.
Notes
M+S
Indications of tire damage or other vehicle de‐
fects:
Winter and all-season tires with better cold
weather performance than summer tires.
▷
▷
Unusual vibrations during driving.
Unusual handling such as a strong tendency
to pull to the left or right.
249
Online Edition for Part no. 01 40 2 606 497 - 03 11 490
In case of tire damage
Approved wheels and tires
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.
The manufacturer of your vehicle recom‐
mends that you use only wheels and tires that
have been approved for your particular vehicle
model.
Drive carefully to the next service center or tire
shop.
For example, despite having the same official
size ratings, variations can lead to body contact
and with it, the risk of severe accidents.
If necessary, have the vehicle towed.◀
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.◀
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.◀
Recommended tire brands
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.◀
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.
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.
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.
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.
Drive conservatively for the first 200 miles/
300 km.
Following tire damage, have the original wheel
and tire combination remounted on the vehicle
as soon as possible.
Retreaded tires
The manufacturer of your vehicle does not rec‐
ommend the use of retreaded tires.

Retreaded tires
Run-flat 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.◀
Label
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.
RSC label on the tire sidewall.
The wheels are composed of special rims and
tires that are self-supporting, to a limited de‐
gree.
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.
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 93
Maximum speed for winter tires
Do not exceed the maximum speed for the
winter tires; otherwise, tire damage and acci‐
dents can occur.◀
Changing run-flat tires
For your own safety, only use run-flat tires. No

Snow chains
Fine-link snow chains
Rotating wheels between axles
Only certain types of fine-link snow chains have
been tested by the manufacturer of your vehicle,
classified as road-safe and recommended.
The manufacturer of your vehicle advises
against swapping wheels between the front and
rear axles.
Consult your service center for more informa‐
tion.
This can impair the handling characteristics.
Use
Storage
Use only in pairs on the rear wheels, equipped
with the tires of the following size:
Store wheels and tires in a cool, dry place with
as little exposure to light as possible.
