Tire Pressure Monitor System (Tpms) - Dodge Ram 2010 Owner's Manual

410 STARTING AND OPERATING
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.
• When 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 position
on the truck. For example, if the spare is used to
replace an outer rear tire it will have to be re-
mounted on the rim so that the wheel is dished
inward. That way the tread design of asymmetrical
tires and the white writing of the OWL tires will
maintain proper position.

TIRE PRESSURE MONITOR SYSTEM (TPMS)

The Tire Pressure Monitoring System (TPMS) will warn
the driver of a low tire pressure based on the vehicle
recommended cold tire inflation placard pressure. The
placard pressure is defined on the Tire and Loading
Information label. The Tire and Loading Information
label is located on the drivers side B-pillar.
The tire pressure will vary with temperature by approxi-
mately 1 psi (6.9 kPa) for every 12°F (6.5°C). This means
that when the outside temperature decreases, the tire
pressure will decrease. Tire pressure should always be set
based on cold inflation tire pressure. This is defined as
the tire pressure after a vehicle has not been driven for
more than three hours, or driven less than one mile after
a three hour period. For information on how to properly
inflate the vehicle's tires, refer to "Tire Pressure" under
"Tires – General Information" in this section. The tire
