Wheels and tiresVehicle equipment
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.
Tire inflation pressure
Safety information
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
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.◀
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.Pressure specifications
The tables below provide all the correct inflation
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 serv‐
ice center.
For correct identification of the right tire inflation
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, 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.
These tire inflation pressures can also be found
on the driver's side door pillar when the driver's
door is open.
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.◀

Tire inflation pressures for driving
above 100 mph or 160 km/h
Adjust the tire inflation pressures
To drive at maximum speeds in excess of
100 mph/160 km/h, adjust pressures to the re‐
spective tire inflation pressures listed on the fol‐
lowing pages in the column for traveling speedsincluding those exceeding 100 mph or 160 km/
h. Otherwise, tire damage and accidents could
occur.◀
Observe all national and local maximum speed
limits; otherwise, violations of the laws could oc‐
cur.

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.
Traction
The traction grades, from highest to lowest, are
AA, A, B, and C.
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.
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.
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. 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.
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.◀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
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 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 Pressure Monitor will not be able to detect
a flat tire, refer to page 90. Your service center
will be glad to advise you.
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 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
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.◀
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.
This can impair the handling characteristics.
Rotating the tires is not permissible when using
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.

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:▷Flat Tire Monitor FTM, refer to page 88▷Tire Pressure Monitor TPM, refer to
page 90
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.
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.

Changing wheels
Notes
Your vehicle is equipped with run-flat tires, refer
to page 236, as standard equipment.
They do not need to be replaced immediately in
the event of a puncture.
No spare tire is available in the case of a flat tire.
When mounting new tires or changing from
summer to winter tires or vice versa, use run-flat
tires for your own safety.
The tools for changing wheels are available as
accessories from your service center.
