it is essential to comply with the follow-

the correct tire.
Rotate tires on the same side only,
since braking characteristics and road
grip could otherwise be adversely af-
fected.
Because of the high speeds this vehicle
can reach, the use of specific tire
brands, specifications and dimensions
is mandatory. Consult any BMW center

as ABS, ATC, ASC+T/DSC. The func-

used.
The speed rating indicates the ap-
proved maximum speed for the tire.
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.<

BMW recommends winter tires (M+S
radial tires) for driving in adverse winter
road conditions. While tires known as
all-season tires (M+S designation) pro-
vide better winter traction than summer
tires with load ratings H, V, W and ZR,
they generally do not achieve the per-
formance of winter tires.

In the interests of sure tracking and
safe steering response, mount winter

Mount only winter tires which have
been approved by BMW. Any BMW
center will be glad to provide you with
information on the best winter tires for
your particular driving conditions.
Protect valve inserts against dirt using
screw-on valve stem caps. Dirt in the
valves frequently leads to slow leaks.
