Operation
Tires and wheels
Rotating wheels
On vehicles with the same wheel size all
around, wheels can be rotated every 3000
to 6 000 miles (5 000 to 10 000 km), or
sooner if necessary, according to the de-
gree of tire wear. The same direction of tire
rotation must be retained.
Rotate the wheels before the characteris-
tic tire wear pattern becomes visible
(shoulder wear on front wheels and tread
center wear on rear wheels).
Thoroughly clean the inner side of the
wheels after each rotation. Check and en-
sure proper tire inflation pressure, activat-
ing the tire inflation pressure monitor if
necessary.
For information on wheel change, see the
“Practical hints” section (
컄
page 323) and
(
컄
page 339).
Warning!
G
Rotate front and rear wheels only if they are
of the same size.
!
If your vehicle is equipped with a tire in-
flation pressure monitor*, there are
electronic components built into the
wheel.
Do not use mounting tools in the area
of the valve as they could damage the
electronic components.
To prevent damage or incorrect instal-
lation, have the tires changed at an au-
thorized Mercedes-Benz Center.
Warning!
G
Have the tightening torque checked after
changing a wheel. Wheels could become
loose if not tightened with a torque of
96 lb-ft (130 Nm).
Only use genuine Mercedes-Benz wheel
bolts specified for your vehicle's rims.
