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.
Tire condition
Inspect your tires frequently for tread wear,
signs of damage and for foreign objects lodged
in the tread. Check the tread pattern depth.
Tire tread
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. As winter tires dis-
play a noticeable loss in their ability to cope with
cold-weather driving conditions once the tread
wears to below 0.16 in/4 mm, to ensure contin-ued safety you should always have such tires
replaced.
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. At a tread
depth of 0.063 in/1.6 mm these indicators, sig-
nal that the tires have reached the legally per-
missible wear limit.
Wheel/tire damage
Due to low-profile tires, please note that
wheels, tires and suspension parts are
more susceptible to road hazard and conse-
quential damages.<
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. Drive carefully to the next BMW
Sports Activity Vehicle Center or tire dealer, or
have the vehicle towed to one of these locations
if necessary.
Tire damage, extending to sudden and com-
plete loss of pressure in extreme cases, can
pose a potentially lethal safety hazard for the
vehicle's occupants and other road users
alike.<

Wheels and tires
86
New wheels and tires
Have new wheels and tires installed only
by your BMW Sports Activity Vehicle
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 danger of subsequent dam-
age and related safety hazards.<
Retreaded tires
BMW does not recommend the use of
retreaded tires, as otherwise driving
safety may be reduced. The causes for this
include the possibly different tire casing struc-
tures 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. If non-approved wheels and tires are
used, BMW cannot evaluate their suitability,
and therefore cannot be held liable for driving
safety.<
You can ask your BMW Sports Activity Vehicle
Center for the correct wheel-and-tire combina-
tion.
The correct wheel-and-tire combination affects
various systems whose function would other-
wise be impaired, e.g. ABS, DSC or xDrive.
To maintain good handling and vehicle
response, use only tires of a single tread config-
uration from a single manufacturer. After a flat
tire, always remember to have the specified
wheel-and-tire combination remounted on the
vehicle as soon as possible.
Recommended tire sizes and brands
BMW tests certain tire brands for each tire size,
classifies them as road-safe and approves
them. These are available at a specialized
dealer, preferably your BMW Sports Activity
Vehicle Center. Observe any country-specific
regulations, e.g. on making a corresponding
entry in the vehicle documents.
The factory-mounted tires have been specially
selected to provide optimized performance
when installed on your vehicle; if properly cared
for, they will provide a combination of safety and
excellent ride comfort.
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.
Observing speed ratings
Never exceed the maximum speed for
which the winter tires are rated. Unpro-
fessional attempts by laymen to service tires
can lead to damage and accidents. Have this
work performed by skilled professionals only.
The technicians at your BMW Sports Activity
V e h i c l e C e n t e r w i l l b e g l a d t o a s s i s t y o u w i t h t h e
required professional knowledge and special-
ized equipment.<
Storage
Store wheels or tires in a cool, dry place, pro-
tecting them against light whenever possible.
Protect the tires against contact with oil, grease
and fuel. Do not exceed the maximum tire infla-
tion pressure indicated on the side wall of the
tire.

Snow chains*
Only certain snow chains have been tested by
BMW and classified and approved as safe. You
can obtain a list of these from your BMW Sports
Activity Vehicle Center. BMW recommends the
use of approved narrow-link snow chains only.
These snow chains are approved exclusively for
use on summer or winter tires in pairs on the
rear wheels.
Observe the manufacturer's instructions when
installing snow chains.
Do not exceed a vehicle speed of 30 mph/
50 km/h with snow chains mounted.
Snow chains may not be mounted on the fol-
lowing tires:
>255/45 R 18
>255/40 R 19
After mounting snow chains, do not ini-
tialize the Flat Tire Monitor.
When you are driving with snow chains, it can
be beneficial to switch off DSC briefly, refer to
page48.<

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 jack and remove it 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
101lbft/140Nm.<
2.Stow the defective wheel in the cargo area.
3.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.<
4.Reinitialize the Flat Tire Monitor, refer to
page49.
Do not initialize the system when driv-
ing with the compact wheel.<
5.Replace the damaged tire with a new one as
soon as possible and have the new wheel
balanced.
Driving with compact wheel
Drive reservedly and do not exceed a
speed of 50 mph/80 km/h. Do not deacti-
vate DSC, as otherwise unstable driving condi-
tions may result.<
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. You should re-equip with
wheels and tires of the original size as quickly as
possible.<
Vehicle battery
Maintenance
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 happy to consult you on all questions
concerning the battery.
Warning lamp
The warning lamp lights up. The bat-
tery is no longer being charged. The
alternator V-belt is defective or there is
a malfunction in the charge current circuit of the
alternator. Have the system checked immedi-
ately.
Do not continue driving if the V-belt is
defective. The engine could be damaged
due to overheating.
Moreover, an increased amount of force is
required for steering if there is a sharp drop in
the onboard supply voltage.<
Charging battery
Charge the battery in the vehicle only when the
engine is not running. Use the connections pro-
vided in the engine compartment. For connec-
tions, refer to Jump starting on page104.
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 secure the
battery to prevent it from tipping over during
transport.<
