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.

Tread
The portion of a tire that comes into contact
with the road.

Rotate front and rear wheels only if the tires
are of the same dimension.

to the tire manufacturer’s recommended
intervals in the tire manufacturer’s warranty

km), or sooner if necessary, according
to the degree of tire wear. The same rotation
(spinning) direction must be maintained.
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.
TWR (Tongue Weight Rating)
G Warning!
Maximum permissible weight on trailer
tongue.
Have the tightening torque checked after
changing a wheel. The wheels could come
loose if they are not tightened to a torque
of 110 lb-ft (150 Nm).
Only use genuine Mercedes-Benz wheel
bolts specified for your vehicle’s rims.
Uniform Tire Quality Grading Standards
A tire information system that provides
consumers with ratings for a tire’s traction,
temperature and treadwear. Ratings are
determined by tire manufacturers using U.S.
government testing procedures. The ratings
are molded into the sidewall of the tire.
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 front-to-rear rotation
pattern that will maintain the intended
