Dodge 2008 Ram 4500 - Manual (Page 335)

Improper alignment will not cause vehicle vibration.
Vibration may be a result of tire and wheel out-of-
balance. Proper balancing will reduce vibration and
avoid tire cupping and spotty wear.
SUPPLEMENTAL TIRE PRESSURE
INFORMATION — IF EQUIPPED
A light load vehicle condition is defined as two passen-
gers [150 lbs (68 kg) each] plus 200 lbs (91 kg) of cargo.
Cold tire inflation pressures for a lightly loaded vehicle

TIRE CHAINS
Use “Class U” chains on 2500/3500 Ram Trucks, or other
traction aids that meet SAE Type “U” specifications.
NOTE: Chains must be the proper size for the vehicle,
as recommended by the chain manufacturer.
CAUTION!
To avoid damage to your vehicle, tires or chains, observe the
following precautions:
• Because of limited chain clearance between tires and other
suspension components, it is important that only chains in good
condition are used. Broken chains can cause serious vehicle
damage. Stop the vehicle immediately if noise occurs that could
suggest chain breakage. Remove the damaged parts of the chain
before further use.
• Install chains as tightly as possible and then retighten after
driving about 1/2 mile (0.8 km).
• Do not exceed 45 mph (72 km/h).
• Drive cautiously and avoid severe turns and large bumps,
especially with a loaded vehicle.
• Do not install tire chains on front wheels of 4x2 vehicles.
• Do not drive for a prolonged period on dry pavement.
• Observe the tire chain manufacturer’s instructions on method of
installation, operating speed, and conditions for usage. Always
use the lower suggested operating speed of the chain manufac-
turer if different than the speed recommended by the
manufacturer.
