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
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 94.
For the Tire Pressure Monitor: after adjusting
the tire inflation pressure to a new value, reset
the Tire Pressure Monitor, refer to page 97.
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.
Seite 228MobilityWheels and tires228
Online Edition for Part no. 01 40 2 954 104 - II/15

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
following pages in the column for traveling
speeds including those exceeding 100 mph or
160 km/h. Otherwise, tire damage and acci‐
dents could occur.◀
Observe all national and local maximum speed
limits; otherwise, violations of the laws could
occur.

Tire Identification Number Tires with DOT codes meet the guidelines of
the U.S. Department of Transportation.
DOT code:
DOT xxxx xxx 0313
xxxx: manufacturer code for the tire brand
xxx: tire size and tire design
0313: tire age
Tire age The tire manufacturing date is contained in the
tire identification mark: DOT ... 0313 means
that the tire was manufactured in the week 3 of
2,013.
BMW recommends that you replace all tires af‐
ter 6 years at most, even if some tires may last
for 10 years.
Uniform Tire Quality Grading Quality grades can be found where applicable
on the tire sidewall between tread shoulder
and maximum section width. For example:
Treadwear 200 Traction AA
Temperature A
DOT Quality Grades
TreadwearTraction AA A B C
Temperature A B C
All passenger car tires must conform to
Federal Safety Requirements in addition
to these grades.◀
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
(11/2) 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 signifi‐
cantly from the norm due to variations in driv‐
ing 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 surfaces 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,
hydroplaning, 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.
Sustained high temperature can cause the ma‐
terial 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 passengerSeite 232MobilityWheels and tires232
Online Edition for Part no. 01 40 2 954 104 - II/15

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 234.
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.
