Replacing wheels/tires

Unprofessional attempts by lay-
men to service tires can lead to

damage and accidents.
Have this work performed by skilled
professionals only. The technicians at
your BMW Sports Activity Vehicle cen-
ter will be glad to assist you with the
required professional knowledge and
specialized equipment.

The correct wheel and tire combination
also affects various systems whose
function would otherwise be impaired,
e.g. ABS, DSC, xDrive.

Have the wheel and tire assemblies bal-
anced every time either a wheel or a tire
is replaced.

BMW does not recommend the
use of retread tires, as otherwise

driving safety may be reduced. Possible
variations in the design and the age –
which could be substantial – of the car-
casses can lead to unusually rapid
wear.

The right wheels and tires

BMW recommends that you use
only wheel and tire combinations

that BMW has tested and approved for
your particular vehicle. Variations in
factors such as manufacturing toler-
ances mean that even wheels and tires
with identical official size ratings could
actually have different dimensions than
the approved units – these differences
could lead to body contact, and with it
the risk of severe accidents. If non-
approved wheels and tires are used,
BMW cannot evaluate their suitability,
and therefore cannot be held liable for
driving safety.

To maintain good handling and vehicle
response, use only tires of a single
tread configuration from a single manu-
facturer. After a flat tire, always remem-
ber to have the original wheel and tire
combination remounted on the vehicle
as soon as possible.

Special features of winter tires

BMW recommends winter tires for use
in cold winter driving conditions.
Although all-season M+S tires provide
better winter traction than summer
tires, they generally fail to provide the

same levels of cold-weather perfor-
mance as winter tires.

When switching to winter tires, observe
the description under Wheel/tire condi-
tion, refer to page

138

, and Replacing

wheels/tires.

Observing speed ratings:

Never exceed the maximum
speed for which the winter tires

are rated. Unprofessional attempts by
laymen to service tires can lead to dam-
age and accidents. Have this work per-
formed by skilled professionals only.
The technicians at your BMW Sports
Activity Vehicle center will be glad to
assist you with the required profes-
sional knowledge and specialized
equipment.

Storage

Store wheels or tires in a cool, dry
place, protecting them against light
whenever possible. Always protect tires
against all contact with oil, grease and
fuels.
Do not exceed the maximum tire infla-
tion pressure indicated on the side wall
of the tire.
