increase tread life, help to maintain mud, snow
and wet traction levels and contribute to a
smooth, quiet ride.
Refer to the "Maintenance Plan" for the proper
maintenance intervals. More frequent rotation
is permissible if desired. The reasons for any
rapid or unusual wear should be corrected prior
to rotation being performed.
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 Rotation (Rearward Cross)
Dual Rear Wheels — If Equipped
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.
Tire Rotation
NOTE:
If your vehicle is equipped with a Tire Pressure
Information System (TPIS):
The Tire Pressure Information System (TPIS)

uses unique sensors in the inner rear wheels
to help identify them from the outer rear
wheels, because of this, the inner and outer
wheel locations can't be switched.
SERVICING AND MAINTENANCE
After a tire rotation is completed, as shown

below, the system can auto learn the loca-
tions of each sensor ID. Auto learning/local-
ization occurs when the vehicle ignition
status is changed from Off to On and speeds
of greater than 5 mph (8km/h) are obtained
and remain over 5 mph (8km/h) for at about
a 15 minute period. You may need to drive
for 20 minutes to account slower speeds and
stops.
If the tires are rotated incorrectly, The auto

localization of the TPIS sensors will fail to
locate correctly resulting in incorrect loca-
tions for the pressure values displayed in the
instrument cluster.
CAUTION!
3500 Dual Rear Tires may only have one

approved direction of rotation. This is to
accommodate the asymmetrical design
(tread pattern) of the On/Off-Road tire and
the use of Outline White Letter (OWL) tires.
