Tire age
DOT … 3510: the tire was manufactured in the
35th week in 2010.
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;
Temperature A
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.Seite 265Wheels and tiresMobility265

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 269, 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.
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.

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 102.
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 recommended.
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:
▷245/50 R 18.▷245/45 R 19.Follow the chain manufacturer's instructions.
Make sure that the snow chains are always suf‐
ficiently tight. Retighten as needed according 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.
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 allowable speed
with snow chains of 30 mph/50 km/h, the rear
axle steering is activated again automatically.

Automatic detection
If functioning properly:
▷Snow chains are mounted. The setting is not
activated
