Sometimes irregular tire wear can be corrected by rotating the tires.
Note:If your tires show uneven wear ask an authorized dealer to check
for and correct any wheel misalignment, tire imbalance or mechanical
problem involved before tire rotation.
Note:Your vehicle may be equipped with a dissimilar spare tire/wheel. A
dissimilar spare tire/wheel is defined as a spare tire and/or wheel that is
different in brand, size or appearance from the road tires and wheels. If
you have a dissimilar spare tire/wheel it is intended for temporary use
only and should not be used in a tire rotation.
Note:After having your tires rotated, check tire pressure and adjust to
the recommended inflation pressure.
WARNING:If the tire label shows different tire pressures for
the front and rear tires and the vehicle is equipped with TPMS
(tire pressure monitoring system), then the TPMS sensors need to be
reset after tire rotation. If the system is not reset, it may not provide a
low tire pressure warning when necessary. See the TPMS reset
procedure in this chapter.

TPMS reset procedure (if applicable)
The TPMS reset tool is ONLY provided for vehicles with different
front and rear tire pressures. The TPMS reset procedure needs to
be performed after tire rotation only on these vehicles.
WARNING:To determine if your vehicle has different
recommended pressures for the front and rear tires, refer to the
Safety Compliance Certification Label or Tire Label which is located on
the B-Pillar or the edge of the driver’s door. SeeVehicle Loadingin
this chapter for more information.
Overview
To provide the vehicle’s load carrying capability, some trucks require
different recommended tire pressures in the front tires as compared to
the rear tires. The Tire Pressure Monitoring System (TPMS) equipped on
these vehicles is designed to illuminate the Low Tire Pressure Warning
indicator at two different pressures; one for the front tires and one for
the rear tires.
Since tires need to be rotated to provide consistent performance and
maximum tire life, the Tire Pressure Monitoring System needs to know
when the tires are rotated to determine which set of tires are on the
front and which are on the rear. With this information, the system can
detect and properly warn of low tire pressures.
WARNING:Always perform the TPMS reset procedure after tire
rotation when recommended pressures are different for the front
and rear tires.
TPMS reset tool
A special TPMS reset tool to reset your TPMS after tire rotation is
provided with vehicles that have different front and rear tire pressures.
The tool is located with your Owner’s Guide materials.
