Storage
Always store wheels and tires in a cool, dry
place with as little exposure to light as pos-
sible. Always protect tires against all con-

Special characteristics of
winter tires

Choosing the right tire
BMW recommends winter tires – M+S tires
for use in cold winter driving conditions.
Although all-season M+S tires provide
better winter traction than standard
summer tires with H, V, W and ZR speed
ratings, they generally fail to provide the
same levels of cold-weather performance
as winter tires.

When mounting, always install winter tires
of a single tread configuration and from a
single manufacturer on all four wheels to
ensure safe tracking and secure steering
response.

Observing speed ratings
Never exceed the maximum speed for
which the winter tires are rated.

Unprofessional attempts by laymen to ser-

Tire condition, tire pressure
Because winter tires display a noticeable
loss in their ability to cope with cold-wea-
ther driving conditions once the tread
wears to below 0.16 in (4 mm), to ensure
continued safety you should always have
such tires replaced.

Always maintain the specified inflation
pressures in all tires, and remember to
have the wheel and tire assemblies bal-
anced every time either a wheel or a tire is
replaced.

Snow chains*
BMW only tests certain snow chains, clas-
sifies them as road-safe and approves
them. Consult your BMW center for more
information. BMW recommends only using
these approved, narrow-link snow chains.
These snow chains are approved exclusi-
vely for use in pairs on the rear wheels, and
should only be mounted on tires with the
dimensions 245/50 R 18. Observe the
manufacturer's instructions when installing
snow chains. Do not exceed a vehicle
speed of 30 mph (50 km/h) with the chains
mounted.
