STEERINGWhen the engine is not running, there is no power
assistance for the steering. Greater force will be
required to steer the vehicle.WHEELS AND TIRESCheck tires regularly for even tread wear, tread depth
(note legal requirements) and signs of external
damage.
Only use wheels and tires of the same size, make and
pattern.
Do not install tires that are not approved for the size
and type of wheel installed or the vehicle itself. Only
use those wheel sizes which were delivered to you by
your authorized Sprinter Dealer.
Use only wheels and tires which have been tested and
approved by the vehicle manufacturer. Break in new tires at moderate speeds for a distance of
about 65 miles (about 100 km).
CAUTION!
Power take off must not exceed 10 kW. Exceeding
the power take off may cause damage to the
auxiliary drive and/or ribbed V-belt.
WARNING!
Fitting other wheel sizes to the vehicle will change
the vehicle’s handling characteristics and may
lead to an accident resulting in severe personal in-
juries, death and property damage.
Only certain tires meeting the tire size/load/speed
rating specifications contained in the Tire
Pressure Tables at the end of this chapter are
certified to conform to FMVSS 120 for the Sprinter
vehicle at this time. Please check your side walls
of your originally equipped tires for specific
makes/sizes, and speed load ratings when you
need to replace your tires.
To prevent accident, injury or possible death, use
only the correct tires for your tire replacement.
Do not use retreaded/ remolded tires. This process
does not always permit previous damage to be
detected. Therefore vehicle safety cannot be
guaranteed if retreaded/remolded tires are fitted
.

208 WHAT TO DO IN EMERGENCIESCentering wheels with wheel bolts
If dual assemblies are used, before placement the inner wheel should be inspected to ensure that all
ball bearing rings are in proper position.
Install the wheel and snug the wheel bolts.
Slightly tighten wheel bolts.
Slowly open jack release va lve to lower vehicle until
tire is resting on ground.
Tighten the wheel bolts in a crosswise pattern to the specified torque with a torque wrench.
Tightening torque for 8,550 lbs (3,880 kgs)
(vehicle type 2500 C/HC/SHC):
Steel wheel – 177 lbf.ft ±7 lbf.ft (240 N.m ±10 N.m)
Light alloy wheel – 138 lbf.ft ±14 lbf.ft
(190 N.m ±20 N.m) Tightening torque for 9,990 lbs (4,530 kgs)
(vehicle type 3500 C/HC/SHC):
Steel wheel – 138lbf.ft ±14lbf.ft (190N.m ±20N.m)
Remove jack and stow it in the vehicle tool kit.
Check the tire pressure.
Re-tighten the wheel bolts to the specified torque with a torque wrench after a distance of 30 miles
(about 50 km).
WARNING!
Do not tighten the wheel bolts and wheel nuts
completely while the vehicle is still jacked up.
The vehicle could tip.
WARNING!
After changing a wheel, you must, for safety reasons, have the specified tightening torque checked. The
wheels could otherwise work loose.
check the tire pressure and correct it if necessary.
retighten the wheel bolts and wheel nuts to the specified tightening torque once the vehicle has
been driven for 30 miles (50 km).
have a reversed direction of tire rotation corrected as soon as possible at a qualified specialist
workshop. The vehicle handling characteristics
could otherwise be affected.
