Pressure specifications
Vehicle equipment
The tables below provide all the correct inflation
pressures for the specified tire sizes at ambient
temperature.
This chapter describes all series equipment as
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 sys‐
tems.
The inflation pressures apply to the tire sizes
approved and tire brands recommended by
BMW; a list of these is available from your serv‐
ice center.
For correct identification of the right tire inflation
pressures, observe the following:
▷
▷
Tire sizes of your vehicle.
Tire inflation pressure
Maximum allowable driving speed.
Safety information
Tire inflation pressures for driving up to
100 mph or 160 km/h
For normal driving up to 100 mph/160 km/h, ad‐
just 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.
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.
Checking the pressure
These tire inflation pressures can also be found
on the driver's side door pillar when the driver's
door is open.
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.
Check the tire inflation pressure regularly
Regularly check the tire inflation pressure
and correct it as needed: at least twice a month
and before a long trip. If you fail to observe this
precaution, you may be driving on tires with in‐
correct 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.◀
Do not exceed the maximum permissible
speed
The maximum permissible speed for these tire
pressures is 100 mph/160 km/h Do not exceed
this speed; otherwise, tire damage and acci‐
dents could occur.◀
After adjusting the tire inflation pressure, reset
the Tire Pressure Monitor, refer to page 90, or
reinitialize the Flat Tire Monitor, refer to
page 88.

Tire age
Tire identification marks
The tire manufacturing date is contained in the
tire identification mark: DOT ... 1012 means that
the tire was manufactured in the week 10 of
2012.
Knowledge of the labeling on the side of the tire
makes it easier to identify and choose the right
tires.
BMW recommends that you replace all tires af‐
ter 6 years at most, even if some tires may last
for 10 years.

Tire Identification Number
Tires with DOT codes meet the guidelines of the
U.S. Department of Transportation.
Treadwear
The treadwear 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 (1 1/2) 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,
however, and may depart significantly from the
norm due to variations in driving habits, service
practices and differences in road characteristics
and climate.
RSC – Run-flat tires
The symbol identifying run-flat tires is a circle
with the letters RSC on the sidewall, refer to
page 236.
M+S
Traction
Winter and all-season tires.
The traction grades, from highest to lowest, are
AA, A, B, and C.
These have better winter properties than
summer tires.
Those grades represent the tire’s ability to stop
on wet pavement as measured under controlled
conditions on specified government test surfa‐
ces of asphalt and concrete. A tire marked C may
have poor traction performance.
XL
Designation for specially reinforced tires.
The traction grade assigned to this tire is based
on straight-ahead braking traction tests, and
does not include acceleration, cornering, hydro‐
planing, or peak traction characteristics.
Tire tread
Summer tires
Do not drive with a tire tread depth of less than
0.12 in/3 mm.
Temperature
There is an increased danger of hydroplaning if
the tread depth is less than 0.12 in/3 mm.
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. Sus‐
tained 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 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.
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
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 pos‐
sible tire failure.◀
Wear indicators are distributed around the tire's
circumference and have the legally required
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
Changing wheels and tires
General information
Mounting
Inspect your tires often for damage, foreign ob‐
jects lodged in the tread, and tread wear.
Information on mounting tires
Have mounting and balancing performed
only by a service center or tire specialist.
Notes
If this work is not carried out properly, there is
the danger of subsequent damage and related
safety hazards.◀
Driving over rough or damaged road surfaces, as
well as debris, curbs and other obstacles can
cause serious damage to wheels, tires and sus‐
pension parts. This is more likely to occur with
low-profile tires, which provide less cushioning
between the wheel and the road. Be careful to
avoid road hazards and reduce your speed, es‐
pecially if your vehicle is equipped with low-pro‐
file tires.
Wheel and tire combination
Information on the right wheel and tire combi‐
nation and rim version for your vehicle can be
obtained from the service center.
Incorrect wheel and tire combinations impair the
function of a variety of systems such as ABS or
DSC.
Indications of tire damage or other vehicle de‐
fects:
▷
▷
Unusual vibrations during driving.
To maintain good handling and vehicle re‐
sponse, use only tires with a single tread con‐
figuration from a single manufacturer.
Unusual handling such as a strong tendency
to pull to the left or right.
Following tire damage, have the original wheel
and tire combination remounted on the vehicle
as soon as possible.
Damage can be caused by driving over curbs,
road damage and similar situations.
In case of tire damage
Approved wheels and tires
If there are indications of tire damage, re‐
duce your speed immediately and have the
wheels and tires checked right away; otherwise,
there is the increased risk of an accident.
The manufacturer of your vehicle recom‐
mends that you use only wheels and tires that
have been approved for your particular vehicle
model.
Drive carefully to the next service center or tire
shop.
For example, despite having the same official
size ratings, variations can lead to body contact
and with it, the risk of severe accidents.
If necessary, have the vehicle towed.
Otherwise, tire damage can present a life-
threatening hazard to vehicle occupants and
other road users.◀
The manufacturer of your vehicle cannot evalu‐
ate non-approved wheels and tires to determine
if they are suited for use, and therefore cannot
ensure the operating safety of the vehicle if they
are mounted.◀
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.◀
Wheels with electronics for TPM Tire
Pressure Monitor
When mounting new tires or changing from
summer to winter tires or vice versa, only use
wheels with TPM electronics; otherwise, the

will be glad to advise you.
vision. You can obtain this sign from the tire spe‐
cialist or from your service center.
Maximum speed for winter tires
Do not exceed the maximum speed for the
winter tires; otherwise, tire damage and acci‐
dents can occur.◀
Recommended tire brands
Run-flat tires
For your own safety, only use run-flat tires. Your
service center will be glad to advise you.
Rotating wheels between axles
The manufacturer of your vehicle advises
against swapping wheels between the front and
rear axles.
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.
This can impair the handling characteristics.
With proper use, these tires meet the highest
standards for safety and handling.
Rotating the tires is not permissible when using
different types of tires.
Storage
Retreaded tires
Store wheels and tires in a cool, dry place with
as little exposure to light as possible.
The manufacturer of your vehicle does not rec‐
ommend the use of retreaded tires.
Always protect tires against all contact with oil,
grease and fuels.
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.◀
Do not exceed the maximum tire inflation pres‐
sure indicated on the side wall of the tire.
Run-flat tires
Winter tires
Label
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 pro‐
vide better winter traction than summer tires,
they do not provide the same level of perform‐
ance 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
RSC label on the tire sidewall.
236
Wheels and tires
Mobility
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 re‐
main drivable to a restricted degree in the event
of a pressure loss.
Driving with a damaged tire:

service center will be glad to advise you.
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 manufacturer'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.
When driving with snow chains, it can be bene‐
ficial to temporarily activate DTC, refer to
page 95.
