Tires and wheels
190
Operation
For these reasons, they wear at unequal
rates, and develop irregular wear patterns.
These effects can be reduced by timely ro-
tation of tires.
The benefits of rotation are especially
worthwhile with aggressive tread designs
such as those on ON/OFF road type tires.
Rotation will increase tread life, help to
maintain mud, snow, and wet traction lev-
els, and contribute to a smooth ride.
If applicable to your vehicle's tire configu-
ration, tires can be rotated according to
the tire manufacturer's recommended in-
tervals in the tire manufacturer's warranty
pamphlet located in your vehicle literature
portfolio. If none is available, tires should
be rotated every 10000 miles (16000 km),
or sooner if necessary, according to the
degree of tire wear.
The same rotation (spinning) direction
must be maintained when mounted; see
"Direction of rotation" (
e page 169).
Rotate tires before the characteristic tire
wear pattern becomes visible (shoulder
wear on front tires and tread center wear
on rear tires).
The reasons for any rapid or unusual wear
should be corrected prior to rotation being
performed.
! If your vehicle is equipped with the tire pres-
sure monitor, each wheel has an electronic com-
ponent.
Tire mounting tools should not be applied in the
area of the valve, as this could damage the elec-
tronic components.
Have the tires changed only at an authorized
Sprinter Dealer.
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" (e page 174).

G Warning
In order to avoid losing a wheel and in order
to reduce the risk of fatal or serious injuries
or vehicle damage, please follow these safety
instructions:
Always replace wheel bolts that are damaged
or rusted.
Never apply oil or grease to wheel bolts.
If a wheel hub thread is damaged, you must
not drive the vehicle. Consult an authorized
Sprinter Dealer.
Only use genuine wheel bolts approved and
specified for your vehicle's rims. Check tight-
ness of wheel bolts or nuts regularly and re-
tighten with a torque wrench, if necessary.
Tighten wheel bolts or nuts in a crisscross
pattern.
For information on mounting bolts and tight-
ening torques, refer to "Installing a wheel"
(
e page 252).
After changing a wheel, the wheel bolts or
nuts must be retightened after the vehicle
has been driven for about 30 miles (50 km)
If 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).
