Tire and Loading Information Placard
This placard tells you important information about the,

2) the total weight your vehicle can carry
3) the tire size designed for your vehicle
4) the cold tire inflation pressures for the front, rear
and spare tires.

Dual Rear Wheels
The tires used on dual wheel assemblies should be
matched for wear to prevent overloading one tire in a set.
To check if tires are even, lay a straight edge across all
four tires. The straight edge should touch all the tires.
CAUTION!
3500 Dual Rear Tires have only one approved direc-
tion of rotation. This is to accommodate the asym-
metrical design (tread pattern) of the ON/OFF road
tire and the use of Outline White Letter (OWL) tires.
²When replacing a flat, 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 posi-
tion on the truck. For example, if the spare is used
to replace an outer rear tire it will have to be
remounted on the rim so that the wheel is dished
inward. That way the tread design of asymmetri-
cal tires and the white writing of the OWL tires
will maintain proper position.

Dual wheel models require a special heavy-duty lug nut
tightening adapter (included with the vehicle) to cor-
rectly tighten the lug nuts. Also, when it is necessary to
remove and install dual rear wheels, use a proper vehicle
lifting device.
NOTE:When installing a spare tire as part of a dual rear
wheel end combination, the tire diameter of the two
individual tires must be compared. If there is a significant
difference, the larger tire should be installed in a front
location. Correct direction of rotation for dual tire instal-
lations must also be observed.
These dual rear wheels should be tightened as follows:
