403 Operation
Tires and wheels
4
\1
Make sure that on one axle just one
type of tire (same size, type con-
struction, load and speed rating) is
used.
Dual rear wheels:
\1
Rotate front tires by axle and the out-
er rear tire side to side if there is no
approved direction of rotation.
The tires used on dual wheel assem-
blies should be matched for wear to
prevent overloading one tire in a set.
\1
To check if tires are even, lay a
straight edge across all four tires.
For information on wheel change, see
the “Practical hints” section
(
\2
page 548).
!
CAUTION
3500 dual rear tires have only one
approved direction of rotation. This is
to accommodate the asymmetrical
design (tread pattern) of the ON/OFF
road tire and the use of Outline White
Letter (OWL) tires.
When replacing a flat tire, the spare
tire may have to be remounted on the
rim or installed at a different location
to maintain the correct placement of
the tire on the wheel relative to the
tire/wheel position on the vehicle.
For example, if the spare is used to
replace an outer rear tire it will have
to remounted on the rim so that the
wheel is dished inward.
That way the tread design of asym-
metrical tires and the white writing of
the OWL tires will maintain proper
position.

405 Operation
Winter driving
4
For safe handling, make sure all winter
tires mounted are of the same make and
have the same tread design.
Always observe the speed rating of the
winter tires installed on your vehicle. If
the maximum speed for which your tires
are rated is below the speed rating of
your vehicle, you must place a notice to
this effect where it will be seen by the driver. Such notices are available at your
tire dealer or any authorized Sprinter
Dealer.
\1
Reactivate the tire pressure monitor.
While studded tires improve perfor-
mance on ice, skid and traction capabil-
ity on wet or dry surfaces may be poorer
than that of non-studded tires. Some
states prohibit studded tires; therefore,
local laws should be checked before us-
ing these tire types.
Warning
G
Winter tires with a tread depth under
1/6 in (4 mm) must be replaced. They are
no longer suitable for winter operation.
Warning
G
If you use your spare tire when winter
tires are fitted on the other wheels, be
aware that the difference in tire charac-
teristics may impair turning stability and
overall driving stability may be reduced.
Adapt your driving style accordingly.
Have the spare tire replaced with a winter
tire at the nearest authorized Sprinter
Dealer.

407 Operation
Winter driving
4
Apply the brakes regularly when making
longer journeys on gritted or salted
roads. This will have the effect of restor-
ing the brakes to their normal level of
performance.
When stopping the vehicle after travel-
ing on roads that have been salted,
check that the brakes are fully functional
before proceeding further.
Use "Class U" chains, or other traction
aids that meet SAE Type "U" specifica-
tions.Snow chai ns m us t be the p rope r si ze f or
the vehicle, as recommended by the
chain manufacturer. They should only be
driven on snow-covered roads at speeds
not to exceed 30 mph (50 km / h). Re-
move chains as soon as possible when
driving on roads without snow.Snow chains
!
CAUTION
Use snow chains on rear wheels only.
Some tire sizes do not leave ade-
quate clearance for snow chains. To
help avoid serious damage to your
vehicle or tires, use of snow chains is
not permissible with the spare wheel.
iWhen driving with snow chains, you
may wish to deactivate the ASR
(\2
page 73) before setting the vehi-
cle in motion. This will improve the
vehicle’s traction.

If you are replacing the tires on the vehi-
cle, you may use the spare wheel as a
road wheel provided that:
\4
the tires are no more than 6 years
old
\4
the wheel and tire have the same
specified design as the road wheels
The spare wheel is located in a spare
wheel bracket under the rear of the vehi-
cle.More information about tire inflation
pressures can be found in the "Opera-
tion" section (
