22 - 6 WHEELS AND TIRES
GENERAL INFORMATION
Original equipment wheels are designed for the
specified Maximum Vehicle Capacity.
All models use steel or cast aluminum drop center
wheels. The safety rim wheel (Fig. 1) has raised sec­
tions between the rim flanges and the rim well.
Fig. 1 Wheel Safety Rim
Initial inflation of the tire forces the bead over
these raised sections. In case of tire failure, the
raised sections hold the tire in position on the wheel
until the vehicle can be brought to a safe stop.
Cast aluminum wheels require special balance
weights and alignment equipment.
Ram Truck Models equipped with dual rear wheels
have eight-stud hole rear wheels. The wheels have a
flat mounting surface (Fig 2). The slots in the wheel
must be aligned to provide access to the valve stem
(Fig. 3).

circumstances substitute these lug nuts, use only
the factory specified lug nuts.
Before installing the wheel, be sure to remove any
build up of corrosion on the wheel mounting surfaces.
