2014 BMW X1 SDRIVE28I tire size

Because the possible driving distance de‐
pends on how the vehicle is used during the
trip, the actual distance may be smaller or
greater depending on the driving speed, road
conditions, external temperature, cargo load,
etc.
Continued driving with a flat tire
Drive moderately and do not exceed a
speed of 50 mph/80 km/h.
A loss of tire inflation pressure results in a
change in the handling characteristics, e.g., re‐
duced lane stability during braking, a longer
braking distance and altered self-steering
properties.◀
Final tire failure
Vibrations or loud noises while driving
can indicate the final failure of the tire. Reduce
speed and stop; otherwise, pieces of the tire
could come loose and cause an accident. Do
not continue driving, and contact your service
center.◀
Message when the system was not
reset
The yellow warning lamp lights up. A
message appears on the Control Dis‐
play.
The system detected a wheel change but was
not reset.
Warnings regarding the current tire inflation
pressure are not reliable.
Check the tire inflation pressure and reset the
system.
Malfunction The small warning lamp flashes in
yellow and then lights up continu‐
ously; the larger warning lamp comes
on in yellow. On the Control Display,
the tires are shown in gray and a message ap‐
pears. No flat tire can be detected.Display in the following situations:▷A wheel without TPM electronics is fitted:

Declaration according to NHTSA/
FMVSS 138 Tire Pressure Monitoring
Systems
Each tire, including the spare (if provided)
should be checked monthly when cold and in‐
flated to the inflation pressure recommended
by the vehicle manufacturer on the vehicle
placard or tire inflation pressure label (If your
vehicle has tires of a different size than the size
indicated on the vehicle placard or tire inflation
pressure label, you should determine the
proper tire inflation pressure for those tires.).
As an added safety feature, your vehicle has
been equipped with a tire pressure monitoring
system (TPMS) that illuminates a low tire pres‐
sure telltale when one or more of your tires is
significantly under-inflated. Accordingly, when
the low tire pressure telltale illuminates, you
should stop and check your tires as soon as
possible, and inflate them to the proper pres‐
sure. Driving on a significantly under-inflated
tire causes the tire to overheat and can lead to
tire failure. Under-inflation also reduces fuel ef‐

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 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.◀
After adjusting the tire inflation pressure, reset
the Tire Pressure Monitor, refer to page 93, or
reinitialize the Flat Tire Monitor, refer to
page 91.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.
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 ex‐
ceed this speed; otherwise, tire damage and
accidents may occur.◀

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 Treadwear
Traction AA A B C
Temperature A B C
Conform to Federal Safety Requirements
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
(1 1/2) times as well on the government course
as a tire graded 100. The relative performanceSeite 237Wheels and tiresMobility237

Tire damage
General information Inspect your tires often for damage, foreign
objects lodged in the tread, and tread wear.
Notes 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.
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.
Damage can be caused by driving over curbs,
road damage and similar situations.
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.
If necessary, have the vehicle towed.
Otherwise, tire damage can present a life-
threatening hazard to vehicle occupants and
other road users.◀
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.◀
Changing wheels and tires
Mounting Information on mounting tires
Have mounting and balancing performed
only by a service center or tire specialist.
If this work is not carried out properly, there is
the danger of subsequent damage and related
safety hazards.◀
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.
To maintain good handling and vehicle re‐
sponse, use only tires with a single tread con‐
figuration from a single manufacturer.
Following tire damage, have the original wheel
and tire combination remounted on the vehicle
as soon as possible.
Approved wheels and tires
The manufacturer of your vehicle recom‐
mends that you use only wheels and tires that have been approved for your particular vehicle
model.
For example, despite having the same official
size ratings, variations can lead to body con‐
tact and with it, the risk of severe accidents.
The manufacturer of your vehicle cannot eval‐
uate non-approved wheels and tires to deter‐
mine if they are suited for use, and therefore
cannot ensure the operating safety of the vehi‐
cle if they are mounted.◀
