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. <
RSC – run-flat tires
You will recognize run-flat tires by a circular
symbol containing the letters RSC on the side
of the tire, refer to page256.
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 freq uently 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 are
distributed over the ti
re's circumference and
are marked on the side of the tire with TWI –
Tread Wear Indicator. If the tire tread has been
driven down to the we ar indicators, a tread
depth of 0.063 in/1.6 mm has been reached.
Wheel/tire damage
Please note that low-pr ofile 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 indi cate 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 Sports Activity Vehicle Center or
tire shop that works ac cording to BMW repair
procedures with corres pondingly trained per-
sonnel. If necessary, have the vehicle towed
there. Otherwise, tire damage can be extremely
dangerous to vehicle occupants and other road
users. <

Run-flat tires
You will recognize run-flat tires by the circular
symbol containing the letters RSC on the side
of the tire.
Run-flat tires consist of partially self-contained
tires and special rims. The sidewall reinforce-
ment ensures that the tire retains some residual
safety in the event of pr essure drop and driving
remains possible to a restricted degree.
To continue driving with a damaged tire:
> With Flat Tire Monitor, refer to Indication of
a flat tire page 101
> With Tire Pressure Monitor, refer to Mes-
sage with low tire inflation pressure
page 103
New wheels and tires
Have new wheels and tires installed only
by your BMW Sports Activity Vehicle
Center or a tire shop that works according to
BMW repair procedures with correspondingly
trained personnel. If this work is not carried out
properly, there is a danger of subsequent dam-
age and related safety ha zards. Make sure that
the new wheels are balanced. <
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
When mounting new tires or changing over
from summer to winter tires and vice versa,
mount Run-Flat Tires for your own safety. Your
BMW Sports Activity Vehicle Center will be
happy to advise you.
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 offi cial 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. If non-approved wheels and tires are
used, BMW cannot evaluate their suitability,
and therefore cannot be held liable for driving
safety. <
When changing to larger wheels and tires,
it may be necessary to make changes to
the wheel-well trim piec e, as otherwise road
users could be endangered or the vehicle could
be damaged. Only have th is work carried out by
a BMW Sports Activity Vehicle Center or a
workshop that works in accordance with BMW
guidelines and uses appropriately trained per-
sonnel. <
You can ask your BMW Sp orts Activity Vehicle
Center for the correct wheel/tire combination.
The correct wheel/tire combination also affects
various systems whose function would other-
wise be impaired, e.g. ABS, DSC, xDrive,
Dynamic Performance Control in the BMW X6,
or Flat Tire Monitor.
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 or iginal wheel and tire
combination remounted on the vehicle as soon
as possible.

summer to winter tires or vice versa, only use
wheels with TPM electronics, otherwise the

this subject.
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 using winter tires for opera-
tion on winter road or at temperatures below
+45 7/+7 6. Although all-season M+S tires
provide better winter traction than summer
tires, they generally fail to provide the same lev-
els of cold-weather performance as winter tires.
Paying attention to speed
Always observe the maximum permissi-
ble speed for the winter tires, otherwise
tire damage may occur, wh ich can result in acci-
dents. <
Storage
Store wheels and tires in a cool, dry place with
as little exposure to lig ht as possible. Always
protect tires against all co ntact with oil, grease
and fuels. Do not exceed the maximum tire
inflation pressure indica ted on the side wall of
the tire.
Rotating wheels between axles
Even with tires of the same size, BMW
recommends that you not rotate the front
tires to the rear or vice versa as this can nega-
tively affect hand ling characteristics.
When the vehicle is equipped with different
tires sizes
*, rotating tires from one axle to the
other is not permitted. <
Snow chains*
BMW only tests certain fine-link snow chains,
classifies them as road-safe and recommends
them. Your BMW Sports Activity Vehicle Center
can provide you with this information.
BMW X5: use is only permitted in pairs on the
rear wheels with tires of the size:
> 255/55 R 18
> 255/50 R 19
BMW X6: it is only permissible to use snow
chains in pairs, on the 255/50 R 19 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. After mounting snow chains, do not ini-
tialize the Flat Tire Monitor
*, as otherwise
incorrect displays can occur.
When you are driving with snow chains, it can
be beneficial to activate DTC briefly, refer to
page 97.<

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 compact wheel.
Secure the wheel by sc rewing 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. Otherwis e, incorrectly tight-
ened lug bolts are a hidden safety risk. The
tightening torque is 101 lb ft/140 Nm. <
2. Stow the defective wheel in the cargo bay.
The defective wheel cannot be stored
under the floor panel flap due to its
size. < 3.
Check and correct the ti re inflation pressure
at the earliest opportunity.
Protect valve stems with valve screw
caps against dirt and contamination.
Dirt in valve stems is a frequent source of
gradual air loss. <
4. Initialize the Flat Tire Monitor, refer to
page 100, or reset the Tire Pressure Moni-
tor, refer to page 102.
5. Replace the damaged tire as soon as possi-
ble and have the new wheel/tire balanced.
Driving with compact wheel
Drive reservedly and do not exceed a
speed of 50 mph/80 km/h. Otherwise,
changes in the driving characteristics could
result, for example reduced track stability on
braking, extended brakin g distance, and altered
self-steering characterist ics in the limit range.
In conjunction with wint er tires, these charac-
teristics are more pronounced. <
Only one compact wheel may be
mounted. Restore the wheels and tires to
their original size as quickly as possible. Failure
to do so is a safety risk. <
Vehicle battery
Battery care
The battery is 100 % main tenance-free, i.e., the
electrolyte will last for the life of the battery
when the vehicle is operated in a temperate cli-
mate. Your BMW Sports Activity Vehicle Center
will be glad to advise in all matters concerning
the battery.
Charging battery
Only charge the battery in the vehicle via the
terminals in the engine compartment with the
engine switched off. Connections, refer to
Jump starting on page 280.
Disposal
Have old batteries disposed of following
