Operation
Tires and wheels
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 3000 to 6000 miles 
(5000 to 10000 km), or sooner if neces-
sary, according to the degree of tire wear. 
The same rotation (spinning) direction 
must be maintained (
page 368).
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 469) and 
(
page 497).
Warning!
G
Have the tightening torque checked after 
changing a wheel. Wheels could become 
loose if not tightened with a torque of 
110 lb-ft (150 Nm).
Only use genuine Mercedes-Benz wheel 
bolts specified for your vehicle’s rims.
