well as country-specific and special equipment
offered for this model series. Therefore, it also
describes equipment that may not be found in
your vehicle, for instance due to the selected
special equipment or the country version. This
also applies to safety-related functions and
systems.
When using the features and systems descri‐
bed here, adhere to local regulations.
Tire inflation pressure Information for your safety
It is not merely the tires' service life, but also
driving comfort and, to a great extent, driving
safety that depend on the condition of the tires
and the maintenance of the specified tire pres‐
sure.
Check the tire inflation pressure regularly
Regularly check the tire inflation pres‐
sure and correct it as needed: at least twice a
month and before a long trip. If you fail to ob‐
serve this precaution, you may be driving on
tires with incorrect tire pressures, a condition
that may not only compromise your vehicle's
driving stability, but also lead to tire damage
and the risk of an accident.◀
Checking the pressure Tires naturally lose pressure uniformly across
all four tires.
Only check the tire inflation pressure when the
tires are cold. This means after a maximum of
1.25 miles/2 km driving or when the vehicle
has been parked for at least 2 hours. When the
tires are warm, the tire inflation pressure is
higher.Tires warm up during driving and the tire infla‐
tion pressure increases as the temperature
rises. The tire inflation pressure specifications
apply to cold tires or tires at ambient tempera‐
ture.
Only check the tire inflation pressure when the
tires are cold. This means after a maximum of
1.25 miles/2 km driving or when the vehicle
has been parked for at least 2 hours.
The values displayed by tire inflation stations
may be up to 0.1 bar, 2 psi too low.
For the Flat Tire Monitor: after adjusting the
tire inflation pressure to a new value, reinitialize
the Flat Tire Monitor, refer to page 92.
For the Tire Pressure Monitor: after adjusting
the tire inflation pressure to a new value, reset
the Tire Pressure Monitor, refer to page 95.
Pressure specifications The tables below provide all the correct infla‐
tion pressures for the specified tire sizes at
ambient temperature.
The inflation pressures apply to the tire sizes
approved and tire brands recommended by
BMW; a list of these is available from your
service center.
For correct identification of the right tire infla‐
tion pressures, observe the following:▷Tire sizes of your vehicle.▷Maximum allowable driving speed.
Tire inflation pressures for driving up
to 100 mph or 160 km/h
For normal driving up to 100 mph/160 km/h,
adjust pressures to the respective tire inflation
pressures listed on the following pages in the
column for traveling speeds up to 100 mph/
160 km/h to achieve optimum driving comfort.

car tires must meet under the Federal Motor
Vehicle Safety Standard No. 109. Grades B
and 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
possible tire failure.◀
RSC – Run-flat tires The symbol identifying run-flat tires is a circle
with the letters RSC on the sidewall, refer to
page 232.
M+S
Winter and all-season tires.
These have better winter properties than
summer tires.
XL
Designation for specially reinforced 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 re‐
quired 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
Driving over rough or damaged road surfaces,
as well as debris, curbs and other obstacles can cause serious damage to wheels, tires and
suspension parts. This is more likely to occur
with low-profile tires, which provide less cush‐
ioning between the wheel and the road. Be
careful to avoid road hazards and reduce your
speed, especially if your vehicle is equipped
with low-profile tires.
Inspect your tires often for damage, foreign
objects lodged in the tread, and tread wear.
Indications of tire damage or other vehicle de‐
fects:
▷Unusual vibrations during driving.▷Unusual handling such as a strong ten‐
dency to pull to the left or right.
In case of tire damage
If there are indications of tire damage, re‐
duce your speed immediately and have the
wheels and tires checked right away; other‐
wise, there is the increased risk of an accident.
Drive carefully to the next service center or tire
shop.

If necessary, have the vehicle towed.◀Repair of tire damage
For safety reasons, the manufacturer of
your vehicle recommends that you do not have
damaged tires repaired; they should be re‐
placed. Otherwise, damage can occur as a re‐
sult.◀
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
remain drivable to a restricted degree in the
event of a pressure loss.
Driving can continue with a damaged tire, refer
to page 94.
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.
Changing wheels and tires
Mounting Information on mounting tires
Have mounting and balancing performed
only by a service center or tire specialist.
If this work is not carried out properly, there is
the danger of subsequent damage and related
safety hazards.◀
Wheel and tire combination
Information on the correct wheel-tire combina‐
tion and rim versions for your vehicle can be
obtained from your service center.
Incorrect wheel and tire combinations impair
the function of a variety of systems such as
ABS or DSC.
To maintain good handling and vehicle re‐
sponse, use only tires with a single tread con‐ figuration from a single manufacturer.
Following tire damage, have the original wheel
and tire combination remounted on the vehicle
as soon as possible.
Approved wheels and tires
The manufacturer of your vehicle recom‐
mends that you use only wheels and tires that have been approved for your particular vehicle
model.
For example, despite having the same official
size ratings, variations can lead to body con‐
tact and with it, the risk of severe accidents.
The manufacturer of your vehicle cannot eval‐
uate non-approved wheels and tires to deter‐
mine if they are suited for use, and therefore
cannot ensure the operating safety of the vehi‐
cle if they are mounted.◀Seite 232MobilityWheels and tires232
Online Edition for Part no. 01 40 2 957 403 - X/14

Recommended tire brands
For each tire size, the manufacturer of your ve‐
hicle recommends certain tire brands. These
can be identified by a star on the tire sidewall.
With proper use, these tires meet the highest
standards for safety and handling.
Retreaded tires The manufacturer of your vehicle does not rec‐
ommend the use of retreaded tires.
Retreaded tires
Possibly substantial variations in the de‐
sign and age of the tire casing structures can
limit service life and have a negative impact on
road safety.◀
Winter tires
The manufacturer of your vehicle recommends
winter tires for winter roads or at temperatures
below +45 ℉/+7 ℃.
Although so-called all-season M+S tires do
provide better winter traction than summer tires, they do not provide the same level of per‐
formance as winter tires.
Maximum speed of winter tires
If the maximum speed of the vehicle is higher
than the permissible speed for the winter tires,
then display a corresponding sign in the field
of vision. You can obtain this sign from the tire
specialist or from your service center.
Maximum speed for winter tires
Do not exceed the maximum speed for
the winter tires; otherwise, tire damage and ac‐
cidents can occur.◀
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.
Rotating wheels between axlesThe manufacturer of your vehicle advises
against swapping wheels between the front
and rear axles.
This can impair the handling characteristics.
Rotating the tires is not permissible when us‐
ing different types of tires.
Storage 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 pres‐
sure indicated on the side wall of the tire.
Snow chains Only certain fine-link snow chains have been
tested by BMW, classified as safe for use and
recommended. Consult your service center for
more information.
Snow chains must be mounted in pairs and on
the rear wheels only. Observe the manufactur‐
er's instructions when mounting snow chains.
Do not exceed a speed of 30 mph/50 km/h
when using snow chains.
Do not initialize the Flat Tire Monitor if snow
chains are mounted; otherwise, the instrument
might issue an incorrect reading.Seite 233Wheels and tiresMobility233
