Wheel and tire combinations
The right choice
Use only tires approved by BMW. Refer
to page 132.
Due to the high speeds this vehicle can
reach, the use of specific brands, spec-
ifications and sizes is mandatory. Con-
sult any BMW center for details.
Comply with all local/national regula-
tions.
The correct wheel-tire combina-
tion affects different systems such
as ABS, ATC and DSC. The function of
these systems is impaired if improper
wheel-tire combinations are used.
For this reason, use only tires of the
same brand and tread pattern. If you
have mounted winter tires and must use
the spare wheel following a flat tire, for
example, remount the approved wheel-
tire combination as soon as possible.<
