Wheel and tire combinations

The right choice

Use only BMW-approved tires. Refer to
page

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. Com-
ply with local/national regulations.

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. In the
event of a flat tire, for example, remount
the approved wheel-tire combination as
soon as possible.

Codes on tires and wheels

The tire codes will aid you in selecting
the correct tire.

The codes on radial tires:

The speed rating indicates the approved
maximum speed for the tire.

= up to 150 mph (240 km/h)

W = up to 167 mph (270 km/h)
Y

= above 167 mph (270 km/h)

ZR = above 150 mph (240 km/h)
