Tire replacement
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
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 age
The 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.
Wheel and tire combinations
The right choice
Never mount wheels and tires that
have not been specifically
approved by BMW for use on your par-
ticular 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 pos-
sible 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 tire, 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 con-
trol.<
Storage
Store tires in a cool, dry place, pro-
tecting them against light whenever
possible. Protect the tires against con-
tact with oil, grease and fuel.
