Wheels and tiresVehicle features and options
This chapter describes all standard, country-
specific and optional features offered with the
series. It also describes features that are not
necessarily available in your car, e. g., due to
the selected options or country versions. This
also applies to safety-related functions and
systems. The respectively applicable country
provisions must be observed when using the
respective features and systems.
Tire inflation pressure Safety information
The tire characteristics and tire inflation pres‐
sure influence the following:▷The service life of the tires.▷Road safety.▷Driving comfort.
Checking the tire inflation pressure
WARNING
A tire with low or missing tire inflation
pressure impacts handling, such as steering
and braking response. There is risk of an acci‐
dent. Regularly check the tire inflation pres‐
sure, and correct it as needed, e.g. twice a
month and before a long trip.◀
Also check the tire inflation pressure of the
emergency wheel in the trunk regularly, and
correct it as needed.
Tires have a natural, consistent loss of tire in‐
flation pressure.
Tires heat up while driving, and the tire infla‐
tion pressure increases along with the tire's
temperature. The tire inflation pressure speci‐
fications relate to cold tires or tires with the
ambient temperature.
Only check the tire inflation pressure when the
tires are cold. This means after driving no more
than 1.25 miles/2 km or when the vehicle has
been parked for at least 2 hours.
The displays of inflation devices may under-
read by up to 0.1 bar, 2 psi.
For Flat Tire Monitor: after correcting the tire
inflation pressure, reinitialize the Flat Tire
Monitor.
For Tire Pressure Monitor: after correcting the
tire inflation pressure, reset the Tire Pressure
Monitor.
Tire inflation pressure specifications
The tire inflation pressure table, refer to
page 187, contains all tire inflation pressure
specifications for the specified tire sizes at the
ambient temperature. The tire inflation pres‐
sure values apply to tire sizes approved by the
manufacturer of the vehicle for the vehicle
type.
To identify the correct tire inflation pressure,
please note the following:▷Tire sizes of your vehicle.▷Maximum permitted driving speed.
Tire inflation pressures up to
100 mph/160 km/h
For speeds of up to 100 mph/160 km/h and for
optimum driving comfort, note the pressure
values in the tire inflation pressure table, refer
to page 187, and adjust as necessary.

3.Wrap the empty sealant container and con‐
nection hose in suitable material to avoid
dirtying the trunk.4.Stow the Mobility System back in the vehi‐
cle.
Distributing the sealant
Immediately drive approx. 5 miles/10 km to en‐
sure that the sealant is evenly distributed in the
tire.
Do not exceed a speed of 50 mph/80 km/h.
If possible, do not drive at speeds less than
12 mph/20 km/h.
To correct the tire inflation pressure
1.Stop at a suitable location.2.Screw the connection hose onto the tire
valve stem.3.Attach the connection hose directly to the
compressor.4.Insert the connector into a power socket
inside the vehicle.5.Correct the tire inflation pressure to
2.5 bar.▷Increase pressure: with the ignition
turned on or the engine running, switch
on the compressor.▷To reduce the pressure: press the but‐
ton on the compressor.
Continuing the trip
Do not exceed the maximum permissible
speed of 50 mph/80 km/h.
Reinitialize the Flat Tire Monitor.
Reinitialize the Tire Pressure Monitor.
Replace the nonworking tire and the sealant
container of the Mobility System as soon as
possible.
Snow chains
Fine-link snow chains
The manufacturer of your vehicle recommends
use of fine-link snow chains. Certain types of
fine-link snow chains have been tested by the
manufacturer of the vehicle and recommended
as road-safe and suitable.
Information regarding suitable snow chains is
available from a dealer’s service center or an‐
other qualified service center or repair shop.

InformationWARNING
The vehicle jack is optimized for lifting
the vehicle and for the jacking points on the
vehicle only. There is risk of injuries. Do not lift
any other vehicle or cargo using the vehicle
jack.◀
Removing the emergency wheel The emergency wheel and the tools are lo‐
cated in the trunk under the cargo floor panel.1.Unscrew the wing nut.2.Remove the cover.3.Remove tool holder.4.Remove emergency wheel.
Prepare wheel change
1.Follow the Safety instructions, refer to
page 214.2.With the wheel chock from the onboard ve‐
hicle tool kit, also secure the vehicle
against rolling away at the front wheel of
the opposite side. For this, place the wheel
chock behind the front wheel diagonally
across.3.Loosen the wheel lug bolts a half turn.
Jacking up the vehicle
1.Place the vehicle jack at the jacking point
closest to the wheel such that the vehicle
jack foot is vertically beneath the vehiclejacking point with the entire surface on the
ground.2.Insert the vehicle jack head in the rectan‐
gular recess of the jacking point for crank‐
ing it up.3.Crank it up until the wheel in question lifts
off of the ground.
Wheel mounting
Mount one emergency wheel only.
1.Unscrew the wheel lug bolts and remove
the wheel.2.Put the new wheel or emergency wheel on
and screw in at least two bolts.
If original BMW light alloy wheels are not
mounted, any accompanying lug bolts also
have to be used.3.Screw in the remaining the lug bolts and
tighten all bolts well in a crosswise pattern.4.Lower the vehicle and remove the vehicle
jack.
After the wheel change
1.Tighten the lug bolts crosswise. The tight‐
ening torque is 101 lb ft/140 Nm.2.Stow the nonworking wheel in the trunk.
The nonworking wheel cannot be stored
under the cargo floor panel because of its
size.3.Check tire inflation pressure at the next op‐
portunity and correct as needed.4.Reinitialize the Flat Tire Monitor.Seite 214MobilityReplacing components214
