NOTE:
On Canadian vehicles only, if your vehicle is equipped
with All-Season type tires on the front and On/Off Road
type tires mounted on the rear, do not use a front to
back rotation pattern. Instead, rotate your tires side to
side at the recommended intervals.
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.
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 below,
the system can auto learn the locations of each sen-
sor ID. Auto learning/localization occurs when the
vehicle ignition status is changed from Off to On and
speeds of greater than 5 mph (8 km/h) are
obtained and remain over 5 mph (8 km/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 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!
•
4500/5500 Dual Rear Tires may only have one
approved direction of rotation. This is to accommo-
date the asymmetrical design (tread pattern) of the
On/Off road tire.

CAUTION!
•
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 vehicle. 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 will maintain proper position.
DEPARTMENT OF TRANSPORTATION
UNIFORM TIRE QUALITY GRADES
The following tire grading categories
were established by the National High-
way Traffic Safety Administration. The
specific grade rating assigned by the
tire's manufacturer in each category is
shown on the sidewall of the tires on
your vehicle.
All passenger vehicle tires must con-
form to Federal safety requirements in
addition to these grades.
