occur.
Tire identification marks
Knowledge of the labeling on the side of the tire
makes it easier to identify and choose the right
tires.
Tire size
Speed letter
Q = up to 100 mph/160 km/h
T = up to 118 mph/190 km/h
H = up to 131 mph/210 km/h
V = up to 150 mph/240 km/h
W = up to 167 mph/270 km/h
Y = up to 186 mph/300 km/h
Z = over 150 mph/240 km/h
Tire Identification Number
Tires with DOT codes meet the guidelines of
the U.S. Department of Transportation.
DOT code:
Tire age
The manufacturing date of tires is contained in
the tire coding: DOT... 0806 indicates that the
tire was manufactured in week 8 of 2006.
BMW recommends that you replace all tires
after 6 years at most, even if some tires may last
for 10 years. This also concerns the tire of the
spare wheel.
Uniform Tire Quality Grading
Quality grades can be found where applicable
on the tire sidewall between tread shoulder and
maximum section width. For example:
Tread wear 200 Traction AA
Temperature A

DOT Quality Grades
Tread wear
Traction AA A B C
Temperature A B C
All passenger car tires must conform to
Federal Safety Requirements in addition
to these grades.<
Tread wear
The tread wear 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 (1γ) 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, how-
ever, and may depart significantly from the
norm due to variations in driving habits, service
practices and differences in road characteris-
tics 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 sur-
faces 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, cor-
nering, hydroplaning, or peak traction charac-
teristics.<
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
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 Vehi-
cle Safety Standard No. 109. Grades B and A
represent higher levels of performance on the
laboratory test wheel than the minimum
required by law.
The temperature grade for this tire is
established for a tire that is properly
inflated and not overloaded. Excessive speed,
underinflation, or excessive loading, either sep-
arately or in combination, can cause heat
buildup and possible tire failure.<
M+S
Winter and all-season tires.
These have better winter properties than sum-
mer tires.
XL
Indicates specially reinforced tires.
Tire condition
Inspect your tires frequently for tread wear,
signs of damage and for foreign objects lodged
in the tread. Check the tread depth.
Minimum tread depth
The tread depth should not drop below 0.12 in/
3 mm, although, for example, European legisla-
tion only specifies a minimum tread depth of
0.063 in/1.6 mm. At tread depths below 0.12 in/
3 mm there is an increased risk of high-speed
hydroplaning, even when only small amounts of
water are present on the road surface.
When winter tires wear down past a tread depth
of 0.16 in/4 mm, they become perceptibly less
suitable for winter conditions. For the sake of
safety, new tires should be installed.

Wear indicators at the tread-groove base, refer
to arrow, are distributed over the tire's circum-
ference and are marked on the side of the tire
with TWI – Tread Wear Indicator. If the tire tread
has been driven down to the wear indicators, a
tread depth of 0.063 in/1.6 mm has been
reached.
Wheel/tire damage
Please note that low-profile tires cause wheels,
tires and suspension parts to be more suscep-
tible to road hazards and consequential dam-
ages.
Unusual vibrations encountered during normal
vehicle operation can indicate tire failure or
some other vehicle defect. This can, for exam-
ple, be caused by driving over curbs. These
kinds of problems may also be signaled by other
changes in vehicle response, such as a strong
tendency to pull to the left or right.
In these cases, reduce speed immedi-
ately and have wheels and tires thor-
oughly checked. To do so, drive carefully to the
nearest BMW center or tire shop that works
according to BMW repair procedures with cor-
respondingly trained personnel. If necessary,
have the vehicle towed there. Tire damage can
be extremely dangerous for vehicle occupants
and other road users.<
New wheels and tires
Have new wheels and tires installed only
by your BMW center or tire shop that
works according to BMW repair procedures
with correspondingly trained personnel. If this
work is not carried out properly, there is a dan-
ger of subsequent damage and related safety
hazards. Make sure that the new wheels are bal-
anced.<
Retreaded tires
BMW does not recommend that you use
retreaded tires, as driving safety may be
impaired. The causes for this include the possi-
bly different tire casing structures and the often
wide variations in their age, which can result in a
limited service life.<
The right wheels and tires
BMW recommends that you use only
wheel and tire combinations that BMW
has tested and approved for your particular
vehicle. Variations in factors such as manufac-
turing tolerances mean that even wheels and
tires with identical official size ratings could
actually have different dimensions than the
approved units – these differences could lead to
body contact, and with it the risk of severe acci-
dents. When selecting the tires, also ensure
that they have a sufficient load-carrying capac-
ity. If non-approved wheels and tires are used,
BMW cannot evaluate their suitability, and
therefore cannot be held liable for driving
safety.<
You can inquire about the right wheel/tire com-
bination at your BMW center.
The correct wheel/tire combination also affects
various systems whose function would other-
wise be impaired, e.g. ABS or DSC.
To maintain good handling and vehicle
response, use only tires of a single tread config-
uration from a single manufacturer. Following
tire damage, have the original wheel and tire
combination remounted on the vehicle as soon
as possible.

Recommended tire brands
Certain tire makes are recommended by BMW
depending on the tire size. You can recognize
these from the clearly visible BMW marking on
the tire sidewall.
When used properly, these tires comply with
the most demanding standards for safety and
vehicle response.
Special characteristics of winter tires
BMW recommends winter tires for use in cold
winter driving conditions. Although all-season
M+S tires provide better winter traction than
summer tires, they generally fail to provide the
same levels of cold-weather performance as
winter tires.
Pay attention to speed
Always observe the maximum permissi-
ble speed for the winter tires, otherwise
tire damage may occur, which can result in acci-
dents.<
After changing wheels/tires
After changing tires or wheels, the slip detec-
tion of the Sequential Manual Transmission
must become familiar with the changed state.
Reinitialize the system for this purpose:
1.Move the selector lever into the idling
position N on a straight stretch of road at a
speed between 20 mph/30 km/h and
90 mph/150 km/h.
2.Pull both shift paddles for approx. 2 sec-
onds.If you do not carry out initialization, the system
will automatically learn the changed state grad-
ually during driving. This may be noticeable
from the clutch opening and closing briefly.
Storage
Always store wheels and tires in a cool, dry
place with as little exposure to light as possible.
Always protect tires against all contact with oil,
grease and fuels. Do not exceed the maximum
tire inflation pressure indicated on the side wall
of the tire.
Snow chains*
BMW only tests certain fine-link snow chains,
classifies them as road-safe and recommends
them. Consult your BMW center for more infor-
mation.
Use is only permitted in pairs, with winter tires
of the size 245/45 R 18 on the rear wheels.
Observe the manufacturer's instructions when
mounting snow chains. Do not exceed a speed
of 30 mph/50 km/h with the chains mounted.
Make sure that the snow chains are always suf-
ficiently tensioned. Retension in accordance
with the chain manufacturer's specifications if
necessary.
After mounting snow chains, do not ini-
tialize the Flat Tire Monitor, otherwise
incorrect displays can occur.
After mounting or removing snow chains, the
slip detection of the Sequential Manual Trans-
mission must become familiar with the altered
state. To do this, reinitialize the system, refer to
After changing wheels/tires.<

Replacing components
194 2.Guide the jack head into the rectangular
recess of the jacking point when cranking
up, refer to illustration detail.
3.Jack the vehicle up until the wheel you are
changing is raised from the ground.
Mounting a wheel
1.Unscrew the lug bolts and remove the
wheel.
2.Remove accumulations of mud or dirt from
the mounting surfaces of the wheel and
hub. Also clean the lug bolts.
3.Position the new wheel or spare wheel.
Secure the wheel by screwing at least two
lug bolts into opposite bolt holes.
When you mount wheels other than Genu-
ine BMW light-alloy wheels, different lug
bolts may also be required.
4.Screw in the remaining lug bolts. Tighten all
the bolts securely in a diagonal pattern.
5.Lower the vehicle and remove the jack from
beneath the vehicle.
After mounting
1.Tighten the lug bolts in a diagonal pattern.
To ensure safety, always have the
lug bolts checked with a calibrated
torque wrench as soon as possible to
ensure that they are tightened to the speci-
fied torque. The tightening torque is
88.5 lb ft/120 Nm.<
2.Check and correct the tire inflation pressure
at the earliest opportunity.
Protect valve stems and valve stem
seal caps against dirt and contamina-tion. Dirt in valve stems is a frequent source
of gradual air loss.<
3.Initialize the Flat Tire Monitor, refer to
page77, and the Sequential Manual Trans-
mission, refer to After changing wheels/
tires on page180.
4.Replace the damaged tire as soon as possi-
ble and have the new wheel/tire balanced.
Stowing wheel and tools
1.Lay the wheel in the tool mounting.
2.Lay the cover on the mounting.
3.Center the wheel and cover relative to the
lashing eyes5.
4.Hook the belt into the lashing eyes.
5.Completely open the tensioning lock.
6.Thread the belt3 through the axis6 of the
tensioning lock without twisting it and ten-
sion it by hand.
7.Tighten the belt firmly with the tensioning
lock by opening and closing the lock several
times.
8.Fold the tensioning lock closed and stow
the protruding belt end.
Driving with spare wheel
With certain wheel-and-tire combinations
the size of the spare wheel differs from
that of the other wheels. The spare wheel is
equivalent to them in all load and speed ranges.
However, to restore the original state, the nor-
mal wheel should be remounted as soon as
possible.<
