DOT, Tire Identification Number (TIN)
U.S. tire regulations stipulate that every tire
manufacturer or retreader must imprint a TIN in
or on the sidewall of each tire produced.
The TIN is a unique identification number. The
TIN enables the tire manufacturers or retreaders
to inform purchasers of recalls and other safety-
relevant matters. It makes it possible for the
purchaser to easily identify the affected tires.
The TIN is made up of manufacturer identifica-
tion code ;, tire size =, tire type code ?and
manufacturing date A.
DOT (Department of Transportation): tire
symbol :indicates that the tire complies with
the requirements of the U.S. Department of
Transportation.
Manufacturer identification code: manufac-
turer identification code ;provides details on
the tire manufacturer. New tires have a code
with two symbols. Retreaded tires have a code
with four symbols.
Further information about retreaded tires
(
Ypage 247).
Tire size: identifier=describes the tire size.
Tire type code: tire type code?can be used by
the manufacturer as a code to describe specific
characteristics of the tire.
Date of manufacture: date of manufactureA
provides information about the age of a tire. The first and second positions represent the week of
manufacture, starting with "01" for the first cal-
endar week. Positions three and four represent
the year of manufacture. For example, a tire that

General notes
If your vehicle is equipped with a spare wheel,
the spare wheel is under the rear of the vehicle
(
Ypage 272).
Information about installing a wheel can be
found in the "Wheel change" section
(
Ypage 267).
Changing wheels
Rotating the wheels
GWARNING
Interchanging the front and rear wheels may
severely impair the driving characteristics if
the wheels or tires have different dimensions. The wheel brakes or suspension components
may also be damaged. There is a risk of acci-
dent.
Rotate front and rear wheels only if the wheels and tires are of the same dimensions.
!On vehicles equipped with a tire pressure
monitor, electronic components are located
in the wheel.
Tire-mounting tools should not be used near
the valve. This could damage the electronic
components.
Only have tires changed at a qualified spe-
cialist workshop.
Always observe the instructions and safety
notes in the "Mounting a wheel" section
(
Ypage 267).
The wear patterns on the front and rear tires
differ, depending on the operating conditions.
Rotate the wheels before a clear wear pattern
has formed on the tires. Front tires typically
wear more on the shoulders and the rear tires in
the center.
If your vehicle's tire configuration allows, you
can rotate the wheels according to the intervals
in the tire manufacturer's warranty book in your
vehicle documents. If no warranty book is avail-
able, the tires should be rotated every 3,000 to
6,000 miles (5,000 to 10,000 km), or earlier if
tire wear requires. Do not change the direction
of rotation.
Clean the contact surfaces of the wheel and the brake disc thoroughly every time a wheel is rota-
ted.
Check the tire pressure and reactivate the tire
pressure monitor if necessary.
Diagram showing tire rotation for single and dual
tires
Single tires: if the tires are of identical dimen-
sions, you can rotate both wheels on both the
front and rear axles so that the tires' original
direction of rotation is maintained. On unidirec-
266Changing wheels
Wheels and tires

tional tires, an arrow on the sidewall shows the
prescribed direction of rotation of the tire.
Twin rear tires:if the tires are of identical
dimensions, you can rotate the wheels on the
front axle and the inner wheels on the rear axle
in pairs such that the original direction of tire
rotation is retained. With unidirectional tires,
you may rotate the outside wheels at the rear
axle from one side to the other.
Direction of rotation
Tires with a specified direction of rotation have
additional benefits, e.g. if there is a risk of hydro-
planing. You will only gain these benefits if the
correct direction of rotation is observed.
An arrow on the sidewall of the tire indicates its
correct direction of rotation.
You may mount 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.
Storing wheels
Store wheels that are not being used in a cool,
dry and preferably dark place. Protect the tires
from contact with oil, grease and fuel.

Raising the vehicle
GWARNING
If you do not position the jack correctly at the
appropriate jacking point of the vehicle, the
jack could tip over with the vehicle raised.
There is a risk of injury.
Only position the jack at the appropriate jack-
ing point of the vehicle. The base of the jack
must be positioned vertically, directly under
the jacking point of the vehicle.
GWARNING
On uphill and downhill slopes, the jack could
tip over with the vehicle raised. There is a risk
of injury.
Do not change wheels on uphill or downhill
gradients. Notify a qualified specialist work-
shop.
!Only position the jack on the jacking points
intended for this purpose. You could other-
wise damage the vehicle.
Observe the following when raising the vehicle:
RWhen raising the vehicle, only use the jack
which Mercedes-Benz has specifically
approved for your vehicle.
RThe vehicle's jack is intended only to raise the
vehicle for a short time when changing a
wheel. It is not suited for performing mainte-
nance work under the vehicle.
RAvoid changing the wheel on uphill and down- hill slopes.
RBefore raising the vehicle, secure it from roll-
ing away by applying the parking brake and
inserting wheel chocks. Never disengage the
parking brake while the vehicle is raised.
RThe jack must be placed on a firm, flat and
non-slip surface. On a loose surface, a large,
load-bearing underlay must be used. On a
slippery surface, a non-slip underlay must be
used, e.g. rubber mats.
RMake sure that the distance between the
underside of the tires and the ground does not
exceed 1.2 in(3 cm).
RNever place your hands or feet under the
ra
ised vehicle.
RNever lie under the raised vehicle.
RNever start the engine when the vehicle is
raised.
RNever open or close a door when the vehicle
is raised.
RMake sure that no persons are present in the
vehicle when the vehicle is raised.
!Only use the jack pump lever middle rod and
the rod with the largest diameter as a lug
wrench extension. Only slide the middle rod
as far as it will go onto the lug wrench. The
rods may otherwise bend and be distorted to
such an extent that they can no longer be
used as a pump lever for the jack.

immediately.
!Vehicles with Super Single tires:if you
install the spare wheel, do not exceed the
maximum speed of 40 mph (60 km/h) and do
not drive further than 65 miles(100 km).
The transmission could otherwise be dam-
aged by the difference in wheel rotation
speeds.
On vehicles with Super Single tires, you must
attach the narrow spare wheel to the rear axle by
means of an adapter. The adapter is bolted to
the spare wheel using the adapter bolts for
transportation.
The handling characteristics of your vehicle are affected when driving with a spare wheel instal-
led. After changing a wheel, drive to the nearest
specialist workshop and have the spare wheel
replaced with a wheel and tire assembly that hasa Super Single tire.
XClean the wheel and wheel hub contact sur-
faces.
XUnscrew the six adapter bolts on the spare
wheel and remove the adapter.
XTighten the adapter with the six adapter boltsevenly in a crosswise pattern through the
outer holes on the wheel hub.

XPush the wheel onto the adapter and attach it.
Mounting a new wheel
GWARNING
Oiled or greased wheel bolts or damaged
wheel bolts/hub threads can cause the wheel bolts to come loose. As a result, you could
lose a wheel while driving. There is a risk of
accident.
Never oil or grease wheel bolts. In the event of
damage to the threads, contact a qualified
specialist workshop immediately. Have the
damaged wheel bolts or hub threads
replaced/renewed. Do not continue driving.
GWARNING
If you tighten the wheel bolts or wheel nuts
when the vehicle is raised, the jack could tip
over. There is a risk of injury.
Only tighten the wheel bolts or wheel nuts
when the vehicle is on the ground.
Always observe the instructions and safety
notes on "Changing a wheel" (
Ypage 266).
Only use wheel bolts or wheel nuts that have
been designed for the wheel and the vehicle. For safety reasons, we recommend that you only
use wheel bolts or wheel nuts which have been
approved for Sprinter vehicles and the respec-
tive wheel.
!For a steel wheel, only use the short wheel
bolts to mount the steel spare wheel. Using
other wheel bolts to mount the steel spare
wheel could damage the brake system.
!On vehicles equipped with a tire pressure
monitor, electronic components are located
in the wheel.
Tire-mounting tools should not be used near
the valve. This could damage the electronic
components.
