Tire Replacement; Rotating Wheels - Mercedes-Benz E320 Operator's Manual

Tire Replacement

Front tires should be replaced in sets.
Furthermore - in the event of tire
replacement - the spare wheel (except
model E 420 with Sport Package), if
possible, should be used on the rear
axle. 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 retightened after approximately
60-300 miles (100-500 km) whenever
wheels are fitted, e.g. when the spare
wheel is used for the first time or when a
set of wheels with M+S tires is installed.
Tightening torque:
80 ft.lb. (110 Nm).
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

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.
