Notes on changing wheels
& WARNING Risk of injury through differ‐
ent wheel sizes
Interchanging the front and rear wheels if the
wheels or tyres have different dimensions
may severely impair the driving characteris‐
tics.
The disk brakes or wheel suspension compo‐
nents may also be damaged.
Rotate front and rear wheels only if the
#
wheels and tyres are of the same
dimensions.
Interchanging the front and rear wheels if the
wheels or tyres have different dimensions can
render the general operating permit invalid.
On vehicles with the same front and rear wheel
size, you can interchange the wheels every 5,000
to 10,000 km depending on the wear. Ensure the
direction of rotation is maintained for the wheels.
It is imperative to observe the instructions and
safety notes on "Changing a wheel" when doing
so.
Wheel size categories of wheels
The determined vehicle speed is displayed in the
instrument cluster and is important for control‐
ling the driving safety systems and driving sys‐
tems. The display accuracy of the speedometer
and the odometer is legally prescribed. Determin‐
ing the speed is dependent on the tyre size or the
rolling circumference of the tyres. The rim diame‐
ter is always specified in inches.
For this reason, the vehicle control units can be
coded for the following three wheel size catego‐
ries:
Wheel size category 1
195/75 R16C
R
205/75 R16C
R
225/65 R16C
R
235/65 R16C
R
235/60 R17C
R
Wheel size category 2
225/75 R16C
R
Wheel size category 3
225/75 R16C FA
R
285/65 R16C RA

Mercedes-Benz recommends that you stay
within a wheel size category when changing a
tyre. In this way, you avoid recoding the con‐
trol units.
If you change the wheel size of your vehicle, for
instance when changing wheels for winter opera‐
tion, check it is assigned to the correct wheel
size category. If the wheel size category changes,
you must have your vehicle's control units reco‐
ded at a qualified specialist workshop.
Otherwise, the display accuracy of the speedom‐
eter and the odometer will be outside the legally
prescribed tolerance. It may also be lower, i.e.
the current road speed is then higher than the
speed shown on the speedometer. If a deviation
is outside the range of tolerance, driving safety
systems and driving systems may be operation‐
ally impaired or may detect a malfunction and
switch themselves off.
Information on the direction of the tyres'
rotation
Tyres with a specified direction of rotation have
additional benefits, e.g. if there is a risk of aqua‐
planing. You will only gain these benefits if the
correct direction of rotation is observed.
An arrow on the sidewall of the tyre indicates its
correct direction of rotation.
You may also fit a spare wheel against the direc‐
tion of rotation. Observe the time restriction on
use as well as the speed limitation specified on
the spare wheel.
Information on storing wheels
Observe the following when storing wheels:
Wheels that have been removed should be
R
stored in a cool, dry and, if possible, dark
place.
Protect the tyres from oil, grease and fuel.
