Wheels and tires  
Pressure specifications  
Vehicle equipment  
The tire inflation pressure table, refer to  
page 186, 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.  
All standard, country-specific and optional  
equipment that is offered in the model series is  
described in this chapter. Therefore, equip‐  
ment is also described that is not available in a  
vehicle, e. g., because of the selected optional  
equipment or country variant. This also applies  
for safety-related functions and systems.  
To identify the correct tire inflation pressure,  
please note the following:  
Tire sizes of your vehicle.  
Tire inflation pressure  
Maximum permitted driving speed.  
Safety information  
Tire inflation pressures up to  
100 mph/160 km/h  
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  
values in the tire inflation pressure table, refer  
to page 186, and adjust as necessary.  
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 pres‐  
sure, and correct it as needed: at least twice a  
month and before a long trip. If you fail to ob‐  
serve this precaution, you may be driving on  
tires with incorrect 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.◀  
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.◀  
After correcting the tire inflation pressure:  
Reinitialize the Flat Tire Monitor.  
Reinitialize the Tire Pressure Monitor.

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 signifi‐  
cantly from the norm due to variations in driv‐  
ing habits, service practices and differences in  
road characteristics and climate.

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 surfaces of asphalt and concrete. A tire  
marked C may have poor traction performance.  
Tires with DOT codes meet the guidelines of  
the U.S. Department of Transportation.  
Tire age  
DOT … 1013: the tire was manufactured in the  
10th week 2013.  
The traction grade assigned to this tire is  
based on straight-ahead braking traction tests,  
and does not include acceleration, cornering,  
hydroplaning, or peak traction characteristics.  
Recommendation  
Regardless of wear, replace tires at least every  
6 years.  
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.  
Sustained high temperature can cause the ma‐  
terial of the tire to degenerate and reduce tire  
life, and excessive temperature can lead to  
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;  
Temperature A

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 re‐  
quired by law.  
Minimum tread depth  
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  
possible tire failure.  
Wear indicators are distributed around the  
tire's circumference and have the legally re‐  
quired minimum height of 0.063 in/1.6 mm.  
They are marked on the side of the tire with  
TWI, Tread Wear Indicator.  
If necessary, have the vehicle towed.◀  
RSC – Run-flat tires  
Run-flat tires, refer to page 199, are labeled  
with a circular symbol containing the letters  
RSC marked on the sidewall.  
Tire damage  
General information  
Inspect your tires often for damage, foreign  
objects lodged in the tread, and tread wear.  
M+S  
Winter and all-season tires with better cold  
weather performance than summer tires.  
Notes  
Driving over rough or damaged road surfaces,  
as well as debris, curbs and other obstacles  
can cause serious damage to wheels, tires and  
suspension parts. This is more likely to occur  
with low-profile tires, which provide less cush‐  
ioning between the wheel and the road. Be  
careful to avoid road hazards and reduce your  
speed, especially if your vehicle is equipped  
with low-profile 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.  
Indications of tire damage or other vehicle de‐  
fects:  
Winter tires  
Do not drive with a tire tread depth of less than  
0.16 in/4 mm.  
Unusual vibrations during driving.  
Unusual handling such as a strong ten‐  
dency to pull to the left or right.  
Below a tread depth of 0.16 in/4 mm, tires are  
less suitable for winter operation.  
Damage can, e. g., be caused by driving over  
curbs, road damage, or similar things.

Wheels and tires  
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; other‐  
wise, 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 nearest service center. If  
necessary, have the vehicle towed.  
For example, despite having the same official  
size ratings, variations can lead to body con‐  
tact and with it, the risk of severe accidents.  
Otherwise, tire damage can be life-threatening  
for vehicle occupants and other traffic partici‐  
pants.◀  
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.◀  
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.  
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.  
If this work is not carried out properly, there is  
the danger of subsequent damage and related  
safety hazards.◀  
With proper use, these tires meet the highest  
standards for safety and handling.  
Wheel and tire combination  
New tires  
Information on the correct wheel-tire combina‐  
tion and rim versions for your vehicle can be  
obtained from your service center.  
Due to technical factors associated with their  
manufacture, tires do not achieve their full  
traction potential until after an initial breaking-  
in period.  
Incorrect wheel and tire combinations impair  
the function of a variety of systems such as  
ABS or DSC.  
Drive conservatively for the first  
200 miles/300 km.  
To maintain good handling and vehicle re‐  
sponse, use only tires with a single tread con‐  
figuration from a single manufacturer.  
Retreaded tires  
The manufacturer of your vehicle does not rec‐  
ommend the use of retreaded tires.  
Following tire damage, have the original wheel  
and tire combination remounted on the vehicle  
as soon as possible.

Wheels and tires  
Mobility  
Retreaded tires  
Always protect tires against all contact with oil,  
grease and fuels.  
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.◀  
Do not exceed the maximum tire inflation pres‐  
sure indicated on the side wall of the tire.  
Run-flat tires  
Winter tires  
The manufacturer of your vehicle recommends  
winter tires for winter roads or at temperatures  
below +45 ℉/+7 ℃.  
Label  
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.  
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 for winter tires  
The support of the sidewall allows the tire to  
remain drivable to a restricted degree in the  
event of a pressure loss.  
Do not exceed the maximum speed for  
the winter tires; otherwise, tire damage and ac‐  
cidents can occur.◀  
Continued driving with a damaged tire, refer to  
page 102.  
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.  
Continued driving with a damaged tire, refer to  
page 99.  
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.  
Rotating wheels between axles  
The manufacturer of your vehicle advises  
against switching wheels between the front  
and rear axles.  
Snow chains  
This can impair the handling characteristics.  
Fine-link snow chains  
Storage  
Only certain types of fine-link snow chains  
have been tested by the manufacturer of your  
vehicle, classified as road-safe and recom‐  
mended.  
Store wheels and tires in a cool, dry place with  
as little exposure to light as possible.
