More information can be found in the
“Technical data” section (
page 357).Spare wheel S 55 AMG and Sport
Package*
In case of a flat tire, you may temporarily
use the spare wheel when observing the
following restrictions:
Do not exceed a vehicle speed of
50 mph (80 km/h).
Drive to the nearest tire repair facility

Never operate the vehicle with more than
one spare wheel mounted.
The spare wheel rim is for temporary use
only. Use for over a total of 12 000 miles
(20 000 km) (aggregate of all uses) may
cause wheel rim failure leading to an acci-
dent and possible injuries.
The spare wheel should only be used tempo-
rarily and replaced with a regular road wheel
as quickly as possible.
Warning!

The dimensions of the spare wheel are dif-
ferent from those of the road wheels. As a
result, the vehicle handling characteristics
change when driving with a mounted spare
wheel. Adapt your driving style accordingly.
Never operate the vehicle with more than
one spare wheel mounted.
The spare wheel is for temporary use only.
When driving with spare wheel mounted, en-
sure proper tire pressure and do not exceed

364 Technical dataRims and tires
Rims and tiresUse only tires and rims which have been
specifically developed for your vehicle and
tested and approved by Mercedes-Benz.
Other tires and rims 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, ex-
hibit dimensional variations and differ-
ent tire deformation characteristics
that could cause them to come into
contact with the vehicle body or axle
parts. Damage to the tires or the vehi-
cle can be the result.
iFurther information on tires and rims is
available at any authorized
Mercedes-Benz Center. A tire inflation
pressure table is located on the fuel fill-
er cap of the vehicle. The tire pressure
should be checked regularly and
should only be adjusted on cold tires.
Follow tire manufacturer’s mainte-
nance recommendation included with
vehicle.
