Tire Pressure Monitor System (Tpms) - RAM 2013 Cargo Van Owner's Manual

The suggested rotation method is the "rearward cross"
shown in the following diagram. This rotation pattern
does not apply to some directional tires that must not be
reversed.

TIRE PRESSURE MONITOR SYSTEM (TPMS)

The TPMS will warn the driver of a low tire pressure
based on the cold inflation tire placard pressure require-
ments found on the tire placard label located on the
driver's-side B-pillar.
The tire pressure will vary with temperature by about 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 - and in outside ambient temperature. Refer
to "Tires – General Information" in "Starting and
Operating" for information on how to properly inflate
the vehicle's tires. The tire pressure will also increase as
the vehicle is driven - this is normal and there should be
no adjustment for this increased pressure.
