289 Operation
Tires and wheels
Rotating tires
Tire rotation can be performed on vehicles
with tires of the same dimension all
around. If your vehicle is equipped with
tires of the same dimension all around,
tires can be rotated, observing a a
front-to-rear rotation pattern that will
maintain the intended rotation (spinning)
direction of the tire (
page 287).
In some cases, such as when your vehicle
is equipped with mixed-size tires (different
tire dimension front vs. rear), tire rotation
is not possible.If applicable to your vehicle's tire configu-
ration, tires can be rotated according to
the tire manufacturer's recommended in-
tervals in the tire manufacturer's warranty
pamphlet located in your vehicle literature
portfolio. If none is available, tires should
be rotated every 3 000 to 6 000 miles
(5 000 to 10 000 km), or sooner if neces-
sary, according to the degree of tire wear.
The same rotation (spinning) direction
must be maintained (
page 287).
Rotate tires before the characteristic tire
wear pattern becomes visible (shoulder
wear on front tires and tread center wear
on rear tires).
Thoroughly clean the mounting face of
wheels and brake disks, i.e. the inner side
of the wheels/tires, during each rotation.
Check for and ensure proper tire inflation
pressure.For information on wheel change, see the
“Practical hints” section (
page 329) and
(
page 353).
Warning!
G
Rotate front and rear wheels only if the tires
are of the same dimension.
If your vehicle is equipped with mixed-size
tires (different tire dimensions front vs.
rear), tire rotation is not possible.
Warning!
G
Have the tightening torque checked after
changing a wheel. Wheels could become
loose if not tightened with a torque of
80 lb-ft (110 Nm).
Only use genuine Mercedes-Benz wheel
bolts specified for your vehicle's rims.

359 Practical hints
Flat tire
Lowering the vehicle
Lower vehicle by turning crank
counterclockwise until vehicle is
resting fully on its own weight.
Remove the jack.1 - 5Wheel bolts
Tighten the five wheel bolts evenly,
following the diagonal sequence
illustrated (1to5), until all bolts are
tight. Observe a tightening torque
of 80 lb-ft (110 Nm).Before storing the jack, it should be fully
collapsed, with handle folded in (storage
position) (
page 331).
Store the jack and the other vehicle
tools in the trunk.
Warning!
G
Vehicles with collapsible tire
(C 55 AMG only):
Inflate collapsible tire only after the wheel is
properly mounted.
Inflate the collapsible tire using the electric
pump (
page 357) before
lowering the ve-
hicle.
Warning!
G
Have the tightening torque checked after
changing a wheel. The wheels could come
loose if they are not tightened to a torque
of 80 lb-ft (110 Nm).
