age and related safety hazards. Make sure that 
the new wheels are balanced.

Retreaded tires
BMW does not recommend the use of 
retreaded tires; otherwise, driving safety 
may be reduced. The causes for this include the 
possibly different tire casing structures and the 
often wide variations in their age, which can 
result in a limited service life.

Correct 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 manufac-
turing tolerances 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 acci-
dents. If non-approved wheels and tires are 
used, BMW cannot evaluate their suitability, 
and therefore cannot be held liable for driving 
safety.

You can ask your BMW Sports Activity Vehicle 
Center for the correct wheel-and-tire combina-
tion.
The correct wheel-and-tire combination affects 
various systems whose function would other-
wise be impaired, e.g. ABS, DSC or xDrive.
To maintain good handling and vehicle 
response, use only tires of a single tread config-
uration from a single manufacturer. After tire 
damage, always remember to have the original 
wheel and tire combination remounted on the 
vehicle as soon as possible.
Wheels equipped with electronics for 
TPM Tire Pressure Monitor
When installing new tires or when changing 
from summer tires to winter tires or vice versa, 
only use wheels equipped with TPM electron-
ics; otherwise, the Tire Pressure Monitor can-
not detect a flat tire, refer to page
. Your 
BMW Sports Activity Vehicle Center will be 
happy to advise you in this regard.
Recommended tire brands
BMW recommends particular tire brands for 
each tire size. You will recognize them by the 
clearly visible BMW identification on the tire 
sidewall.
With proper use, these tires meet the highest 
standards for safety and handling characteris-
tics.
Special characteristics of winter tires
BMW recommends winter tires for use on win-
ter road surfaces or at temperatures below 
+45
7/+76. Although all-season M+S tires do 
provide better winter traction than summer 
tires, they generally fail to provide the same lev-
els of cold-weather performance as winter tires.
Observing speed ratings
Never exceed the maximum speed for 
which the winter tires are rated.
<
Storage
Store wheels or tires in a cool, dry place, pro-
tecting them from light whenever possible. Pro-
tect the tires from contact with oil, grease and 
fuel. Do not exceed the maximum tire inflation 
pressure indicated on the side wall of the tire.
Changing wheels from one axle to 
another
BMW does not recommend changing the front 
wheels to the back or vice versa as this can 
impair handling characteristics.
