TWR (permissible trailer drawbar load)
The TWR is the maximum permissible weight
that may act on the ball coupling of the trailer tow hitch.
Wear indicator
Narrow bars (tread wear bars) that are dis-
tributed over the tire tread. If the tire tread is level with the bars, the wear limit of 00CDin
(1.6 mm) has been reached.
Distribution of the vehicle occupants
The distribution of vehicle occupants over
designated seat positions in a vehicle.
Maximum permissible payload weight
Nominal load and goods/luggage load plus
68 kg (150 lbs) multiplied by the number of
seats in the vehicle. Flat tire
General notes
If your vehicle is equipped with a spare wheel, the spare wheel is under the rear of the vehi-
cle (Y page 312).
Information about installing a wheel can be
found in the "Wheel change" section
(Y page 306).
When you replace a tire, we recommend that
you also replace the tire valve. Please observe
the safety-relevant information on tire valve
(Y page 290). Changing wheels

WARNING
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 loca-
ted in the wheel.
Tire-mounting tools should not be used
near the valve. This could damage the elec- tronic components.
Only have tires changed at a qualified spe-cialist workshop.
Always observe the instructions and safety
notes in the "Mounting a wheel" section
(Y page 306).
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 inter-
vals in the tire manufacturer's warranty book
in your vehicle documents. If no warranty
book is available, 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 rotated.
Check the tire pressure and reactivate the tire pressure monitor if necessary. Diagram showing tire rotation for single and dual

X Using the pump lever, slowly turn the low-
ering screw on the jack through approx-
imately one revolution and carefully lower
the vehicle (Y page 307).
X Put the jack aside.
X Pull the rod with the smallest diameter off
the pump lever.
The shortened pump lever serves as a lug
wrench extension.
X Starting with the middle rod, slide the lug
wrench extension as far as it will go onto
the lug wrench.
X Using the extended lug wrench, tighten the
wheel bolts evenly in a crosswise pattern in the sequence indicated (0043 to0084).
Tighten the wheel bolts to the following
tightening torques:
R Steel wheel 177 lb-ft(240 Nm)
R Alloy wheel 133 lb-ft(180 Nm)
Tighten the wheel nuts to a tightening tor-
que of 133 lb-ft (180 Nm).
X Push the piston on the hydraulic jack in
again and close the pressure release
screw.
X Stow the jack and the rest of the vehicle
tools in the vehicle again.
i You can now install the hub caps on steel
wheels with wheel bolts. The installing pro-
cedure depends on whether the hub cap
acts as a trim that covers the whole wheel,
or just covers the center. X
Wheel with hub cap: position the opening
for the tire valve in the hub cap over the tire
valve.
X Push the edge of the hub cap with both
hands against the wheel until it clicks into
place. Make sure the hub cap retaining
catches engage on the steel wheel.
X Wheel with central hub cap: position the
retaining lugs of the central hub cap over
the wheel bolts.
X Hit the middle of the hub cap to engage it on
the wheel.
X Secure the faulty wheel in the spare wheel
bracket (Y page 313).
X Vehicles with Super Single tires: transport
the defective rear wheel in the load area.
The rear wheel is too large for the spare
wheel bracket.
X Check the tire pressure of the newly moun-
ted wheel and adjust it if necessary.
Observe the recommended tire pressure
(Y page 288).
X Retighten the wheel bolts or wheel nuts to
the specified tightening torque after the
vehicle has been driven for 30 miles
(50 km).
When using a wheel/spare wheel with a new
or newly painted wheel rim, have the wheel
bolts/nuts retightened again after approx-
imately 600 to 3,000 miles (1,000 to
5,000 km). Observe the specified tightening
torque.
i Vehicles with the tire pressure monitor
system: all mounted wheels must be equip- ped with functioning sensors. Wheel and tire combination
General notes
! Retreaded tires are neither tested nor rec-
ommended for Sprinter vehicles, since pre-
vious damage cannot always be detected
on retreaded tires. We can therefore not
guarantee driving safety. Do not mount Wheel and tire combination
