Wheels and tires

120

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-sup-

porting 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 73.

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 75. Your BMW

center will be glad to advise you.

Recommended tire brands

Certain makes of tire are recommended by

BMW for each tire size. They are marked with a

clearly visible BMW designation on the sidewall

of the tire.
