Wheels and tires
238
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 page239.
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 Sports Activity Vehicle Center or
tire shop that works according to BMW repair
procedures with correspondingly 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 pressure 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 page93
>With Tire Pressure Monitor, refer to Mes-
sage with low tire inflation pressure page95
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 hazards. 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.
For safety reasons, BMW recommends
that you do not have damaged run-flat
tires repaired; they should be replaced. Other-
wise it is not possible to rule out occurrences of
consequential damage.<
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. 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 piece, as otherwise road
users could be endangered or the vehicle could
be damaged. Only have this 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 Sports 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 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 original wheel and tire
combination remounted on the vehicle as soon
as possible.

Changing wheels
Your BMW is equipped with run-flat tires as
standard. As a result, it is not necessary to
change the wheel immediately in the case of air
loss in the event of a breakdown.
To continue driving with a damaged tire:
>With Flat Tire Monitor, refer to Indication of
a flat tire page93
>With Tire Pressure Monitor, refer to Mes-
sage with low tire inflation pressure page95
You will recognize run-flat tires by a circular
symbol containing the letters RSC on the side
of the tire, refer to Run-flat tires, page239.
When mounting new tires, or changing from
summer to winter tires or vice versa, use run-flat
tires for your own safety. No spare tire is avail-
able in case of a flat tire. Your BMW Sports
Activity Vehicle Center will be happy to advise
you. Also refer to New wheels and tires,
page239.
Suitable tools for changing tires are avail-
able as accessories at your BMW Sports
Activity Vehicle Center.<
Jacking points for vehicle jack
The jacking points for the vehicle jack are
located in the positions shown.
Compact wheel*
Safety precautions in the event of a flat
tire or wheel change: park the vehicle as
far as possible from passing traffic and on solid
ground. Switch on the hazard warning flashers.
Set the parking brake and engage transmission
position P.
Have all vehicle occupants get out of the vehicle and ensure that they remain outside the imme-
diate area in a safe place, such as behind a
guardrail.
If a warning triangle

appropriate distance from the rear of the vehi-
cle. Comply with all safety guidelines and regu-
lations.
Change the wheel only on a level, firm surface
which is not slippery. The vehicle or the jack
could slip to the side if you attempt to raise the
vehicle on a soft or slippery surface such as
snow, ice, tiles, etc.
Position the jack on a firm support surface.
Do not use a wooden block or similar object as a
support base for the jack, as this would prevent
it from extending to its full support height and
reduce its load-carrying capacity.
To avoid serious or fatal injury: never lie under
the vehicle, and never start the engine while it is
supported by the jack.<
What you will need
To avoid rattling noises later on, note the posi-
tions of the tools before removing them, then
return them to their initial positions after com-
pleting work.
The tools are located in the mount under the
floor panel flap.

Removing compact wheel
The compact wheel is located in the cargo bay
under the floor panel.
1.Remove the tool mount.
2.Unscrew the wing nut 1.
3.Remove the washer 2 laterally.
4.Remove the compact wheel.
Preparing wheel change
1.Observe the safety precautions above.
2.Loosen the lug bolts a half turn.
Jacking up vehicle
1.Position the vehicle jack at the jacking point
closest to the wheel so that the entire sur-
face of the jack base rests on the ground
perpendicularly beneath the jacking point.
The vehicle jack is designed for
changing wheels only. Do not attempt
to raise another vehicle model with it or to
raise any load of any kind. To do so could
cause accidents and personal injury.<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 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. Otherwise, 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 tire 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
page92, or reset the Tire Pressure Monitor,
refer to page94.
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.
The driving characteristics change, for example
reduced track stability on braking, extended
braking distance, and altered self-steering
characteristics in the limit range. In conjunction
with winter tires, these characteristics 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 % maintenance-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 page256.
Disposal
Have old batteries disposed of following
replacement at your BMW Sports Activity
Vehicle Center or bring them to a collection
point. Maintain the battery in an upright position
for transport and storage. Always restrain the
battery to prevent it from tipping over during
transport.<
Power failure
After a temporary power loss, the functioning of
some equipment may be limited and require
reinitialization. Individual settings are also lost
and must be updated:
>Seat, mirror and steering wheel memory
The positions must be stored again, refer to
page44.
>Time and Date
The values must be updated, refer to
pages81, 82.
>Radio
Stations must be stored again if necessary,
refer to page168.
>Navigation system
Wait until the system starts, refer to
page159.
Fuses
Never attempt to repair a blown fuse and
do not replace a defective fuse with a sub-
stitute of another color or amperage rating, as
this could lead to a circuit overload, ultimately
resulting in a fire in the vehicle.<
Spare fuses, a pair of plastic tweezers and infor-
mation on the fuse assignment are located near
the fuses in the cargo bay.
