The reasons for any rapid or unusual wear
should be corrected prior to rotation being
performed.
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, refer to "Recommended tire in-
flation pressure" (\2page 210).
Rotation pattern for single and dual rear
wheelsSingle rear wheels:
\1Rotate the tires by axle. Never change
the direction of rotation of your tires.
\1Make sure that on one axle just one
type of tire (same size, type construc-
tion, load and speed rating) is used.
!
CAUTION
If your vehicle is equipped with the tire
pressure monitor*, each wheel has an
electronic component.
Tire mounting tools should not be ap-
plied in the area of the valve, as this
could damage the electronic compo-
nents.
Have the tires changed only at an
authorized Sprinter Dealer.
Warning
G
In order to avoid loosing a wheel and in or-
der to reduce the risk of fatal or serious in-
juries or vehicle damage, please follow
these safety instructions:
\4Always replace wheel bolts that are
damaged or rusted.
\4Never apply oil or grease to wheel bolts.
\4If a wheel hub thread is damaged, you
must not drive the vehicle. Consult an
authorized Sprinter Dealer.
Only use genuine wheel bolts approved
by the vehicle manufacturer and speci-
fied for your vehicle’s rims. Check tight-
ness of wheel bolts or nuts regularly and
retighten with a torque wrench, if neces-
sary. Tighten wheel bolts or nuts in a
crisscross pattern. For information on
mounting bolts and tightening torques,
refer to "Installing a wheel"
(\2page 320).
\4After changing a wheel, the wheel bolts
or nuts must be retightened after the ve-
hicle has been driven for about 30 miles
(50 km).
\4If new or repainted rims are fitted, the
wheel bolts or nuts must be retightened
again after about 600 to 3000 miles
(about 1000 to 5000 km).

Wheels with centering by wheel bolts:
\1Screw in the wheel bolts and tighten
them finger-tight.

2Wheel bolt for steel wheelor wheels with wheel nuts:
For wheels with wheel nuts:
\1Center the wheel nut cover over the
wheel and push it onto the wheel.
\1Screw on the wheel nuts and tighten
them finger tight.
Lowering the vehicle
\1Slowly open the jack’s pressure release
screw one turn using the pump lever
(\2page 322) and lower the vehicle
slowly.
\1Put the jack to one side.Tightening torque pattern
1 – 6 Wheel bolts
\1Tighten all the wheel bolts and wheel
nuts evenly in the sequence indicated.
As an extension for the wheel wrench,
use the shaft from the jack’s 3-part
pump lever that has the largest diame-
ter.
iOn vehicles with light-alloy wheels, you
will find short wheel bolts suitable for
the steel spare wheel in the vehicle tool

CAUTION
The tightening torque is:
\4for wheel bolts 177 lb-ft (240 Nm)
(steel wheel)/133 lb-ft (180 Nm)
(light-alloy wheel).
\4for wheel nuts 133 lb-ft (180 Nm)
