Wheels and tires
112
Tire age
For various reasons, such as the development
of brittleness, BMW recommends tire replace-
ment after no more than 6 years, regardless of
the actual wear of the tires.
The manufacturing date of tires is contained in
the tire coding:
DOT ... 3408 means that the tire was manufac-
tured in week 34 of 2008.
Run-Flat Tires
The symbol identifying Run-Flat Tires is a circle
with the letters RSC on the sidewall.
Run-Flat Tires comprise a conditionally self-
supporting tire and a special rim. The reinforce-
ment in the sidewalls ensures that the tire can
continue to be used subject to certain restric-
tions, even if depressurized.
For information on continuing to drive with a flat
tire, refer to Indication of a flat tire on page
67
.
New wheels and tires
Have new wheels and tires installed only
by your BMW center or tire shop that
works according to BMW repair procedures
with correspondingly trained personnel. If this
work is not carried out properly, there is a dan-
ger of subsequent damage and related safety
hazards. Make sure that the new wheels are bal-
anced.
<
Retreaded tires
BMW recommends that you do not use
retreaded tires, since driving safety may
be impaired. The causes for this include poten-
tially different tire casing structures and often
wide variations in tire age, which can result in a
limited service life.
<
Correct wheels and tires
When mounting new tires or changing over
from summer to winter tires and vice versa,
mount Run-Flat Tires for your own safety. In the
event of a flat, no spare wheel is available. Your
BMW center will be glad to advise you.
BMW recommends that you use only
wheel and tire combinations that BMW
has tested and approved for your particular
vehicle. Variations in factors such as manufac-
turing tolerances mean that even wheels and
tires with identical official size ratings could
actually have different dimensions, which could
lead to body contact and thus to severe acci-
dents. If non-approved wheels and tires are
used, BMW cannot evaluate their suitability,
and therefore cannot guarantee their driving
safety.
<
You can inquire about the right wheel/tire com-
bination at your BMW center.
The correct combination of wheels and tires is
also necessary to ensure reliable operation of
various vehicle systems such as ABS, DSC or
FTM.
To maintain good handling and vehicle
response, use only tires of a single brand and
tread configuration. After a tire has been dam-
aged, mount the previous wheel and tire combi-
nation again as soon as possible.
Wheels with Tire Pressure Monitor
TPM electronics
When mounting new tires or changing over
from summer to winter tires, or vice versa, only
use wheels with TPM electronics; otherwise the
Tire Pressure Monitor may not be able to detect
a puncture, refer to page
69
. Your BMW center
will be glad to advise you.
