Tire Replacement
Front 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 approx. 60 miles (100 km) at
moderate speed.
It is imperative that the wheel
mounting bolts be fastened to a
tightening torque of 80 ft .lb. (110 Nm)
whenever wheels are mounted.
For rim and tire specifications, refer to
"Technical Data"
Warning!
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.
Rotating Wheels
Rotation of wheels does not apply to
model E 55 AMG with summer tires.
The wheels can be rotated according to
the degree of tire wear while retaining
the same direction of travel.
Rotating, however, should be carried
out at the scheduled service intervals,
before the characteristic tire wear
pattern (shoulder wear on front wheels
and tread center wear on rear wheels)
becomes visible, as otherwise the
driving properties deteriorate.
Important!
Unidirectional tires must always be
mounted with arrow on tire sidewall
pointing in direction of vehicle forward
movement.
Notes:
Thoroughly clean the inner side of the
wheels any time you rotate the wheels
or wash the vehicle underside.
The use of retread tires is not
recommended. Retread tires may
adversely affect the handling
characteristics and safety of the vehicle.
Dented or bent rims can cause tire
pressure loss and damage to the tire
beads. For this reason, check rims for
damage at regular intervals. The rim
flanges must be checked for wear
before a tire is mounted. Remove burrs,
if any.
Check and ensure proper tire inflation
pressure after rotating the wheels. For
Tire Inflation Pressure refer to Index.
