CAUTION
Chains on the tires of only one tandem
axle can damage the driveline U-joints
and the interaxle differential. Repairs
could be costly and time-consuming.
Failure to comply may result in equip-
ment damage.
Speed Restricted Tires
WARNING
This vehicle may be equipped with
speed restricted tires. Check each
tire’s sidewall for maximum rated
speed. The vehicle should not be op-
erated at sustained speed in excess of
maximum rated speed. Failure to com-
ply with these speed restrictions could
cause sudden tire failure which can re-
sult in death, personal injury or proper-
ty damage.
Greenhouse Gas Certified Tires
Verify if your vehicle is equipped with
Greenhouse Gas certified tires by checking
the Vehicle Emission Control label on the
driver's side door frame. If these tires were
installed at the factory, Lower Rolling
Resistance codes (LRR) identify which
tires are certified.
NOTE
The tires installed on this vehicle at the
factory as original equipment may be
certified for Greenhouse Gas and Fuel
Efficiency regulations. Replacement
tires must be of equal or lower rolling
resistance level (TRRL or Crr). Consult
with your tire supplier(s) for appropri-
ate replacement tires.
In order to limit the rolling resistance of the
tires and optimize fuel economy, the
maintenance procedures specified by the
tire manufacture must be followed. Please
see Vehicle Emissions Limited Express
Warranty for warranty on greenhouse gas
certified tires.
Wheels
Information on maintaining your vehicle's
wheels.
After the vehicle travels about 50 to 100
miles (80 to 160 km), wheel mountings
seat in and will lose some initial torque.
Check hub/wheel mountings after this
initial period and retighten. Threads should
be clean and dry. Do not lubricate wheel
nuts or studs.
WARNING
Never use oil or grease on studs or
nuts; improper torque readings will re-
sult, which could cause improper
wheel clamping and could lead to a
wheel failure resulting in an accident.
Failure to comply may result in death,
personal injury, equipment or property
damage.
