On new vehicles retightening is carried
out during the 1st inspection.
Retightening is also necessary 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:
110 ft. lb. (150 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
(identified by Mercedes star)
specified for the particular rim type.
Failure to do so can result in the
bolts loosening and possibly an
accident.
Rotating Wheels
Tire rotation is permissible only, if all
four wheel rims are of the same size.
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 maintenance
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 snow tires must always
be mounted with arrow on tire sidewall
pointing in direction of vehicle forward
movement.
Note:
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.
