Wheels and tires
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.
M+S
Winter and all-season tires with better cold
weather performance than summer tires.
Tire tread
Summer tires
Do not drive with a tire tread depth of less than
0.12 inches/3 mm.
Indications of tire damage or other vehicle mal‐
functions:
There is an increased risk of hydroplaning if
the tire tread depth is less than 0.12 in‐
ches/3 mm.
▷
▷
Unusual vibrations while driving.
Unusual handling such as a strong ten‐
dency to pull to the left or right.
Winter tires
Do not drive with a tire tread depth of less than
0.16 inches/4 mm.
Damage can, e.g., be caused by driving over
curbs, road damage, or similar things.
Safety information
Below a tread depth of 0.16 inches/4 mm, tires
are less suitable for winter operation.
WARNING
Damaged tires can lose tire inflation
pressure, which can lead to loss of vehicle
control. There is a risk of an accident. If tire
damage is suspected while driving, immedi‐
ately reduce speed and stop. Have wheels and
tires checked. For this purpose, drive carefully
to the nearest dealer’s service center or an‐
other qualified service center or repair shop.
Have vehicle towed or transported as
needed.◀
Minimum tread depth
WARNING
Wear indicators are distributed around the
tire's circumference and have the legally re‐
quired minimum height of 0.063 in‐
ches/1.6 mm.
Damaged tires can lose tire inflation
pressure, which can lead to loss of vehicle
control. There is a risk of an accident. Do not
repair damaged tires, but have them re‐
placed.◀
They are marked on the side of the tire with
TWI, Tread Wear Indicator.
Changing wheels and tires
Tire damage
Mounting
General information
Inspect your tires regularly for damage, foreign
objects lodged in the tread, and tread wear.
Have mounting and wheel balancing carried
out by a dealer’s service center or another
qualified service center or repair shop.

they achieve their full traction potential after a
break-in time.
Wheel and tire combination
You can ask the dealer’s service center or an‐
other qualified service center or repair shop
about the correct wheel/tire combination and
wheel rim versions for the vehicle.
Drive conservatively for the first
200 miles/300 km.
Retreaded tires
The manufacturer of your vehicle does not rec‐
ommend the use of retreaded tires.
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.
WARNING
Retreaded tires can have different tire
casing structures. With advanced age the serv‐
ice life can be limited. There is a risk of an acci‐
dent. The manufacturer of your vehicle does
not recommend the use of retreaded tires.◀
Following tire damage, have the original wheel
and tire combination remounted on the vehicle
as soon as possible.
WARNING
Winter tires
Winter tires are recommended for operating on
winter roads.
Wheels and tires which are not suitable
for your vehicle can damage parts of the vehi‐
cle, e.g., due to contact with the body due to
tolerances despite the same official size rating.
There is a risk of an accident. The manufac‐
turer of your vehicle strongly suggests that you
use wheels and tires that have been recom‐
mended by the vehicle manufacturer for your
vehicle type.◀
Although so-called all-season M+S tires 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 attach a corresponding information label/
sticker in the field of view. The label is available
from a dealer’s service center or another quali‐
fied service center or repair shop.
Recommended tire brands
With mounted winter tires, observe and adhere
to the permissible maximum speed.
Run-flat tires
If you are already using run-flat tires, for your
own safety you should replace them only with
the same kind. No spare tire is available in the
case of a flat tire. Further information is availa‐
ble from a dealer’s service center or another
qualified service center or repair shop.
For each tire size, BMW recommends certain
tire brands. These can be identified by a star
on the tire sidewall.
New tires
Tire traction is not optimal due to manufactur‐
ing circumstances when tires are brand-new;

Rotating wheels between axles
Changing run-flat tires
Different wear patterns can occur on the front
and rear axles depending on individual driving
conditions. The tires can be rotated between
the axles to achieve even wear. Further infor‐
mation is available from a dealer’s service cen‐
ter or another qualified service center or repair
shop. After rotating, check the tire pressure
and correct, if needed.
For your own safety, only use run-flat tires. No
spare tire is available in the case of a flat tire.
A dealer’s service center will be glad to answer
additional questions at any time.
Repairing a flat tire
Rotating the tires between the axes is not per‐
missible on vehicles with different tire sizes or
rim sizes on the front and rear axles.
Safety measures
▷
Park the vehicle as far away as possible
from passing traffic and on solid ground.
▷
▷
Switch on the hazard warning system.
Storage
Secure the vehicle against rolling away by
setting the parking brake.
Store wheels and tires in a cool, dry place with
as little exposure to light as possible.
▷
▷
Turn the steering wheel until the front
wheels are in the straight-ahead position
and engage the steering wheel lock.
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.
Have all vehicle occupants get out of the
vehicle and ensure that they remain out‐
side the immediate area in a safe place,
such as behind a guardrail.
Run-flat tires
▷
If necessary, set up a warning triangle at an
appropriate distance.
Label
Mobility System
Concept
With the Mobility System, minor tire damage
can be sealed temporarily to enable continued
travel. To accomplish this, sealant is pumped
into the tires, which seals the damage from the
inside.
RSC label on the tire sidewall.
The compressor can be used to check the tire
inflation pressure.
The wheels consist of tires that are self-sup‐
porting, to a limited degree, and possibly spe‐
cial rims.
General information
The support of the sidewall allows the tire to
remain drivable to a restricted degree in the
event of a tire inflation pressure loss.
▷
Follow the instructions on using the Mobi‐
lity System found on the compressor and
sealant container.
Follow the instructions for continued driving
with a flat tire.
