Replacing wheels/tires 
Unprofessional attempts by laymen to 
service tires can lead to damage and 
accidents.
Have this work performed by skilled pro-
fessionals only. The technicians at your 
BMW center will be glad to assist you with 
the required professional knowledge and 
specialized equipment.

The correct wheel and tire combination 
affects various systems whose function 
would otherwise be impaired, e.g. ABS or 
DSC.
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 retreaded tires, as otherwise driv-
ing safety may be reduced. Possible varia-
tions in the design and the age – which 
could be substantial  – of the carcasses 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 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 accidents. If non-
approved wheels and tires are used, BMW 
cannot evaluate their suitability, and there-
fore 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 manufacturer. 
After a flat tire, always remember to have 
the original wheel and tire combination 
remounted on the vehicle as soon as pos-
sible. 
Recommended tire brands
BMW tests certain tire brands for each tire 
size, classifies them as road-safe and 
approves them. You can find out about 
these at specialized dealers or at your 
BMW center. Observe any country-specific 
regulations, e.g. on making a correspond-
ing entry in the vehicle documents.
The factory-mounted tires have been spe-
cially selected to provide optimized perfor-
mance when installed on your vehicle; if 
properly cared for, they will provide a com-
bination of safety and excellent ride com-
fort.
Run-flat tires
If your BMW is equipped with run-flat tires, 
refer to Run-flat tires, only use these tires, 
as in the event of a breakdown there is no 
spare wheel available.
Special characteristics of winter 
tires 
BMW recommends winter tires for use in 
cold winter driving conditions. Although 
so-called all-season M+S tires provide bet-
ter winter traction than summer tires, they 
generally fail to provide the same levels of 
cold-weather performance as winter tires.
When switching to winter tires, observe the 
description at Tire condition, and Replac-
ing wheels/tires, refer to page 
Run-flat tires 
If your BMW is equipped with run-flat tires, 
refer to Run-flat tires, only use these tires, 
as in the event of a breakdown there is no 
spare wheel available.
Observing speed ratings
Never exceed the maximum speed 
for which the winter tires are rated. 
Unprofessional attempts by laymen to ser-
vice tires can lead to damage and acci-
dents. Have this work performed by skilled 
professionals only. The technicians at your 
BMW center will be glad to assist you with 
the required professional knowledge and 
specialized equipment.
