OverviewControlsMaintenanceRepairsDataIndex
Tire replacement Wheel and tire combinationsUniform Tire Quality GradingQuality 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
Do not use retreaded tires, since
driving safety may be impaired.
This is due to the possible variations in
casing structures and, in some cases,
to their extreme age, which can lead to
a decrease in their durability.< Tire ageThe date on which the tire was manu-
factured is indicated by the code on the
sidewall:
DOT ... 2601 indicates that the tire was
manufactured in Week 26 of the year
2001.
Although tires may have a theoretical
service life of up to 10 years, BMW
strongly recommends that you replace
all tires after an absolute maximum of
6 years.
The right choice
Never mount wheels and tires that
have not been specifically
approved by BMW for use on your
particular model. Although other wheels
and tires may theoretically have the
same dimensions, variations in factors
such as manufacturing tolerances can
result in contact between tire and body-
work, ultimately leading to serious acci-
dents. If non-approved wheels and tires
are used, BMW cannot evaluate their
suitability, and therefore cannot be held
liable for driving safety.<
BMW has tested certain tires for each
tire size, rated them according to road
safety and approved them. Your BMW
center can inform you which tires have
been tested in this way. Observe
possible national guidelines, e.g.
regarding entry into vehicle documents.
The correct wheel and tire combi-
nation affects different systems
such as ABS, ATC, ASC+T/DSC. The
function of these systems is impaired if
improper wheel and tire combinations
are used.
Always ensure that all of the tires
mounted on the vehicle are the same
series, from the same manufacturer and
with the same tread pattern. If you have
to mount the spare tire in response to a
flat, etc., you should remount a tire of
the correct specifications as soon as
possible.<
The use of rims and wheel bolts
that do not meet the specifica-
tions of the original factory-installed
equipment will affect the safe operation
of your vehicle and may cause an acci-
dent and personal injury.
Never mix tires of different design, such
as steel-belted radials with radial bias-
belted or bias-ply tires, etc. Mixing tire
types will adversely affect roadholding
and can lead to loss of vehicle
control.< Storage Store tires in a cool, dry place,
protecting them against light whenever
possible. Protect the tires against
contact with oil, grease and fuel.

Engine oil
Continuous exposure to used oil
has caused cancer in laboratory
testing. For this reason, any skin areas
that come into contact with oil should
be thoroughly washed with soap and
water.
Always store oil, grease, etc., out of
reach of children. Comply with all
warning labels and information on lubri-
cant containers.<
Comply with the applicable envi-
ronmental laws regulating the
disposal of used oil.<
Specified engine oilsThe quality of the engine oil selected
has critical significance for the opera-
tion and service life of an engine.
Based on extensive testing, BMW has
approved only certain engine oils.
Use only approved "BMW High
Performance Synthetic Oil."
If you are unable to obtain "BMW High
Performance Synthetic Oil," you can
add small amounts of synthetic oil in
between oil changes. Only use oils with
the API SH specification or higher.
Ask your BMW center for details
concerning the specific "BMW
High Performance Synthetic Oil" or
"synthetic oils" which have been
approved.<
You can also call BMW of North
America at 1-800-831-1117 or visit the
website: www.bmwusa.com to obtain
this information.
Viscosity ratingsViscosity is the oilflow rating as estab-
lished in SAE classes.
The selection of the correct SAE class
depends on the climatic conditions in
the area where you typically drive your
BMW.
Approved oils are in SAE classes
5W-40 and 5W-30.<
These oils may be used for driving in all
ambient temperatures.
