Wheels and tires<br />
Tire age<br />
For various reasons, such as the development<br />
of brittleness, <strong>BMW</strong> recommends tire replacement<br />
after no more than 6 years, regardless of<br />
the actual wear of the tires.<br />
The manufacturing date of tires is contained in<br />
the tire coding:<br />
DOT ... 1010 means that the tire was<br />
manufactured in week 10 of 2010.<br />
Run-flat tires<br />
The symbol identifying run-flat tires is a circle<br />
with the letters RSC on the sidewall.<br />
Run-flat tires comprise a conditionally self-supporting<br />
tire and a special rim. The reinforcement<br />
in the sidewalls ensures that the tire can<br />
continue to be used subject to certain restrictions,<br />
even if depressurized.<br />
For information on continuing to drive with a flat<br />
tire, refer to Indication of a flat tire, page 84.<br />
New wheels and tires<br />
Have new wheels and tires installed only<br />
by your <strong>BMW</strong> center or tire shop that<br />
works according to <strong>BMW</strong> repair procedures<br />
with correspondingly trained personnel. If this<br />
work is not carried out properly, there is a danger<br />
of subsequent damage and related safety<br />
hazards. Make sure that the new wheels are balanced.<<br />
Retreaded tires<br />
<strong>BMW</strong> recommends that you do not use<br />
retreaded tires, since driving safety may<br />
be impaired. The causes for this include potentially<br />
different tire casing structures and often<br />
wide variations in tire age, which can result in<br />
a limited service life.<<br />
Correct wheels and tires<br />
When mounting new tires or changing over<br />
from summer to winter tires and vice versa,<br />
mount run-flat tires for your own safety. In the<br />
event of a flat, no spare wheel is available. Your<br />
<strong>BMW</strong> center will be glad to advise you.<br />
<strong>BMW</strong> recommends that you use only<br />
wheel and tire combinations that <strong>BMW</strong><br />
has tested and approved for your particular<br />
vehicle. Variations in factors such as manufacturing<br />
tolerances mean that even wheels and<br />
tires with identical official size ratings could<br />
actually have different dimensions, which could<br />
lead to body contact and thus to severe accidents.<br />
If non-approved wheels and tires are<br />
used, <strong>BMW</strong> cannot evaluate their suitability,<br />
and therefore cannot guarantee their driving<br />
safety.<<br />
You can inquire about the right wheel/tire combination<br />
at your <strong>BMW</strong> center.<br />
The correct combination of wheels and tires is<br />
also necessary to ensure reliable operation of<br />
various vehicle systems such as ABS, DSC or<br />
FTM.<br />
To maintain good handling and vehicle<br />
response, use only tires of a single brand and<br />
tread configuration. After a tire has been damaged,<br />
mount the previous wheel and tire combination<br />
again as soon as possible.<br />
Wheels with Tire Pressure Monitor<br />
TPM electronics<br />
When mounting new tires or changing over<br />
from summer to winter tires, or vice versa, only<br />
use wheels with TPM electronics; otherwise,<br />
the Tire Pressure Monitor may not be able to<br />
detect a puncture, refer to page 84. Your<br />
<strong>BMW</strong> center will be glad to advise you.<br />
