Tire Replacement
Front and rear tires should be replaced in sets. Rims
and tires must be of the correct size and type. For
dimensions, see “Technical Data”.
We recommend that you break in new tires for
approximately 60 miles (100 km) at moderate speed.It is imperative that the wheel mounting bolts be
fastened to a tightening torque of 110 ft.lb. (150 Nm)
whenever wheels are mounted.
For rim and tire specifications, refer to “Technical Data”.
Wa r n i n g !
Worn, old tires can cause accidents. If the tire tread
is badly worn, or if the tires have sustained
damage, replace them.When replacing rims, use only genuine
Mercedes-Benz wheel bolts specified for the
particular rim type. Failure to do so can result in
the bolts loosening and possibly an accident.

immediately.Incorrect mounting bolts or improperly tightened
mounting bolts can cause the wheel to come off.
This could cause an accident. Be sure to use the
correct mounting bolts.Wa r n i n g !
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 accident and possible injuries.The spare wheel should only be used temporarily,
and replaced with a regular road wheel as quick as
possible.S 55 AMG and Sport Package:
The dimensions of the spare wheel are different
from those of the road wheels. As a result, the
vehicle handling characteristics change when
driving with a mounted spare wheel.
