Wheels and tires
Tire inflation pressure
Safety information
The tire characteristics and tire inflation pres‐
sure influence the following:
▷
The service life of the tires.
▷ 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.
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.◀
After correcting the tire inflation pressure, rein‐
itialize the Tire Pressure Monitor.
Pressure specifications
The tire inflation pressure table, refer to
page 242, contains all pressure specifications
for the specified tire sizes at the ambient tem‐
perature. Pressure specifications apply to ap‐
proved tire sizes and recommended tire brands.
This information can be obtained from your
service center.
To identify the correct tire inflation pressure,
please note the following:
▷ Tire sizes of your vehicle.
▷ Vehicle load.
▷ Maximum allowable 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 val‐
ues in the tire inflation pressure table, refer to
page 242, and adjust as necessary. These pressure values can also be found on the
tire inflation pressure label on the driver's door
pillar.
Maximum permissible speed
Do not exceed 100 mph/160 km/h; other‐
wise, tire damage and accidents may result.

Recommendation
Regardless of wear, replace tires at least every
6 years.
Uniform Tire Quality Grading
Quality grades can be found where applicable
on the tire sidewall between tread shoulder and
maximum section width.
For example: Treadwear 200; Traction AA;

DOT Quality Grades
Treadwear
Traction AA A B C
Temperature A B C
All
passenger car tires must conform to Federal
Safety Requirements in addition to these
grades.
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 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.
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.
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.
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.
Temperature grade for this tire
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.
If necessary, have the vehicle towed.◀
RSC – Run-flat tires
Run-flat tires, refer to page 252, are labeled with
a circular symbol containing the letters RSC
marked on the sidewall.
M+S
Winter and all-season tires with better cold
weather performance than summer tires.
Tire tread
Summer tires
Do not drive with a tire tread depth of less than
0.12 in/3 mm.
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.
Below a tread depth of 0.16 in/4 mm, tires are
less suitable for winter operation. Seite 250
250 Online Edition for Part no. 01 40 2 606 469 - 03 11 490
Wheels and tires

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

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
