For the proper maintenance intervals page 265.
More frequent rotation is permissible if desired. The
reasons for any rapid or unusual wear should be cor-
rected 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.
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.
NOTE:
If your vehicle is equipped with a Tire Pressure Informa-
tion 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.
•
After a tire rotation is completed, as shown, the sys-
tem can auto learn the locations of each sensor ID.
Auto learning/localization 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 min-
utes to account slower speeds and stops.
•
If the tires are rotated incorrectly, The auto localiza-
tion of the TPIS sensors will fail to locate correctly
resulting in incorrect locations for the pressure val-
ues 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.
•
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
remounted 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.
