Use only tires approved by BMW. 
Refer to the information beginning on 
page 

.

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, ATC and ASC+T/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. In the 
event of a flat tire, for example, remount 
the approved wheel-tire combination as 
soon as possible.
