Wheel and tire combinations
The right choice
Use only tires approved by BMW. Refer
to page 122.
Due to the high speeds this vehicle can
reach, the use of specific brands, spec-
ifications and sizes is mandatory.
Consult any BMW center for details.
Comply with local/national regulations.
The correct wheel-tire combina-
tion affects different systems such
as ABS, DSC, RDW.
The function of these systems is im-
paired if improper wheel-tire combina-
tions are used.
For this reason, use only tires of the
same brand and tread pattern. In the
event of a flat tire, for example, remount
the approved wheel-tire combination as
soon as possible.<
