For vehicles with twin tires with a GVW of
11,030 lbs or 12,125 lbs, only use tires with
the dimension LT 215/85 R16 which have
been approved for this vehicle by the manu‐
facturer. It is not permissible to use tires with
different dimensions; doing so may lead to a
general operating permit being rendered
invalid.

Vehicles with single tires:
For vehicles with single tires with a GVW less
than or equal to 9,480 lbs, only use tires with
the dimension LT 245/75 R16 which have
been approved for this vehicle by the manu‐
facturer. It is not permissible to use tires with
different dimensions; doing so may lead to a

Vehicles with Super Single tires:
For vehicles with single tires with a GVW of
11,030 lbs, only use tires with the dimen‐
sions 225/75 R16C (FA) and 285/65 R16C
(RA) which have been approved for this vehi‐
cle by the manufacturer. It is not permissible
to use tires with different dimensions; doing
so may lead to a general operating permit
being rendered invalid.

Notes on changing wheels
&
WARNING Risk of injury through differ‐
ent wheel sizes
Interchanging the front and rear wheels if the
wheels or tires have different dimensions may
severely impair the driving characteristics.
The wheel brakes or wheel suspension com‐
ponents may also be damaged.
#
Rotate front and rear wheels only if the
wheels and tires are of the same dimen‐
sions.
On vehicles that have the same size front and
rear wheels, rotate the wheels according to the
intervals in the tire manufacturer's warranty book
in your vehicle documents. If this is not available,
rotate the tires every 3,000 (5,000) to
6,000 miles (10,000 km), depending on the
degree of wear. Ensure that the direction of rota‐
tion is maintained.
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 tire size or the
rolling circumference of the tires. The rim diame‐
ter is always specified in inches.
For this reason, the vehicle control units can be
coded for the following wheel size categories:
Wheel size category 3
R
225/75 R16C FA
R
285/65 R16C RA
R
LT245/75 R16
R
LT215/85 R16

Mercedes-Benz recommends that you stay
within a wheel size category when changing a
tire. 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 that it is assigned to the correct
wheel size category. If the wheel size category
changes, you must have your vehicle's control
units recoded 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.
