Rims and tires
Rims and tires
!For safety reasons, only use tires and rims
which have been tested and approved by
Mercedes-Benz for use on SLR vehicles. Tires
approved by Mercedes-Benz are developed to
provide best possible performance in conjunc-
tion with the driving safety systems on your
vehicle such as ABS or ESP
®.
!Using tires and rims other than those ap-
proved by Mercedes-Benz can have detrimental
effects, such as

Poor handling characteristics

Increased noise

Increased fuel consumption
Moreover, tires and rims not approved by
Mercedes-Benz may, under load, exhibit dimen-
sional variations and different tire deformation
characteristics that could cause them to come
into contact with the vehicle body or axle parts.
This may result in damage to the tires or the
vehicle.
iFurther information on tires and rims is
available at any authorized Mercedes-Benz Cen-
ter. A placard with the recommended tire infla-
tion pressures is located on the driver’s door
B-pillar. Some vehicles may have supplemental
tire pressure information for driving at high
speeds (
page 268) or for vehicle loads less
than the maximum loaded vehicle condition. If
such information is provided, it can be found on
the placard located on the inside of the fuel filler
flap. The tire pressure should be checked regu-
larly and should only be adjusted on cold tires.
Follow tire manufacturer’s maintenance
recommendation included with vehicle.
