BMW 2004 Z4 Roadster 3.0i Manual Do Proprietário

Unprofessional attempts by laymen to 
service tires can lead to damage and 

accidents. 
Have this work performed by skilled pro-
fessionals only. Any BMW center has the 
required technical knowledge and the 
proper equipment and will be happy to 
assist you.

<

The correct wheel and tire combination 
also affects various systems that would 
otherwise be impaired, for example ABS or 
DSC.

Have the wheels balanced after each tire or 
wheel replacement. 

BMW advises against using retreaded 
tires, since driving safety may be 

impaired. This is due to possible variations 
in casing structures and, in some cases, to 
their extreme age, factors which can lead 
to a decrease in their durability.

<

BMW recommends using only wheels 
and tires that have been tested and 

approved by BMW for your particular vehi-
cle model, as otherwise body contact and 
serious accidents can result despite the 
use of the same nominal size, e.g. due to 
manufacturing tolerances. If non-approved 
wheels and tires are used, BMW cannot 
evaluate their suitability, and therefore can-
not be held liable for driving safety.

<

To maintain good handling and vehicle 
response, use only tires of a single brand 
and tread configuration. In the event of a 
flat tire, remount the previous wheel and 
tire combination as soon as possible.

BMW tests certain tire brands for each tire 
size, classifies them as road-safe and 
approves them. You can best find out 
about these at a specialized shop, particu-
larly your BMW center. Observe any coun-
try-specific regulations, e.g. on making a 
corresponding entry in the vehicle docu-
ments.

The factory-approved radial-ply tires are 
matched to your vehicle and have been 
selected to provide optimum safety and 
driving comfort when used properly.

Use only Run Flat tires, since no spare 
wheel is available in the event of a flat.

BMW recommends the use of winter tires 
for operation under winter road conditions. 
While all-season tires, with M+S designa-
tion, provide better winter traction than 
summer tires, they generally do not achieve 
the full performance of winter tires. 

For mounting winter tires, refer to the 
descriptions under Tire condition and 
Wheel and tire replacement, pages 

.

Use only winter Run Flat tires, since no 
spare wheel is available in the event of a 
flat.

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 technicans at your 
BMW center will be glad to assist you with 
the required professional knowledge and 
specialized equipment.

<

Store tires in a cool, dry place, protecting 
them against light whenever possible. Pro-
tect the tires from contact with oil, grease 
and fuel. Do not exceed the maximum tire 
inflation pressures specified on the tire 
sidewall.
